This complexity was causing bugs, making the app hard to maintain, and preventing incremental feature development HOW: Deleted all complex state management components including AppStateProvider, ServiceLocator, and multi-responsibility UI widgets. Removed unnecessary services and models not needed for core audio functionality. This creates a clean foundation where services own their data and UI components directly consume service streams without intermediary coordinators --- lib/core/utils/constants.dart | 190 - lib/core/utils/logging_service.dart | 407 -- lib/models/analysis_result.dart | 474 -- lib/models/analysis_result.freezed.dart | 3537 --------------- lib/models/analysis_result.g.dart | 371 -- lib/models/conversation_model.dart | 339 -- lib/models/conversation_model.freezed.dart | 1801 -------- lib/models/conversation_model.g.dart | 182 -

Each feature must work before adding the next, ensuring the app is always functional and eliminating the bugs caused by over-engineering HOW: Implemented RecordingScreen as a simple StatefulWidget that directly integrates with AudioServiceImpl streams for real-time updates. Added timer display consuming recordingDurationStream, audio level indicator consuming audioLevelStream, and FileManagementScreen for playback.

Too many permissions (Bluetooth, Speech, Location) were causing initialization failures when only microphone permission was needed for basic audio recording HOW: Simplified Info.plist to only request microphone permission, cleaned Podfile to remove unused permission handlers, and reduced pubspec.yaml dependencies to only flutter_sound, permission_handler, and freezed for data models. This eliminates potential permission-related crashes and reduces app complexity --- ios/Flutter/AppFrameworkInfo.plist | 2 +- ios/Podfile | 13 +- ios/Podfile.lock | 40 +- ios/Runner.xcodeproj/project.pbxproj | 6 +- .../xcshareddata/xcschemes/Runner.xcscheme | 6 +- .../xcshareddata/xcschemes/debug.xcscheme | 87 +++++ .../xcshareddata/IDEWorkspaceChecks.plist | 8 -

Subject: [PATCH 89/99] prompt(docs): Update documentation to reflect proven clean architecture approach * Architecture.md - Documents actual implemented patterns: - Direct service-to-UI communication via StatefulWidget + Streams - Eliminates complex state management (AppStateProvider removed) - Phase 1 completion proven with working audio foundation * TechnicalSpecs.md - Updated with real Dart/Flutter implementation: - Concrete code examples from actual working implementation - flutter_sound integration patterns - StatefulWidget with StreamSubscription approach * SLA.md - Changed from service uptime to development process SLA: - Phase delivery schedule with Phase 1 marked complete - Quality gates for each incremental step - Proven audio foundation as baseline for future phases * README.md - Updated to reflect current minimal dependencies: - Removed references to complex state management - Updated project structure to match clean implementation - Simplified setup instructions These docs now accurately represent the working foundation built following Linus Torvalds principles: good taste, simplicity, elimination of special cases, and clear data ownership. --- .gitignore | 3

It does not rely on any bit reservoir, + * a frame will be strictly encoded in the bytes budget given by + * the user (or transport layer). + * + * However, the bitrate (bytes budget for encoding a frame) can be + * freely changed at any time. But will not rely on signal complexity, + * it can follow a temporary bandwidth increase or reduction. + * + * - Unlike classic codecs, the LC3 codecs does not run on fixed amount + * of samples as input. It operates only on fixed frame duration, for + * any supported samplerates (8 to 48 KHz). Two frames duration are + * available 7.5ms and 10ms. + * + * + * --- About 44.1 KHz samplerate --- + * + * The Bluetooth specification reference the 44.1 KHz samplerate, although + * there is no support in the core algorithm of the codec of 44.1 KHz. + * We can summarize the 44.1 KHz support by "you can put any samplerate + * around the defined base samplerates". Please mind the following items : + * + * 1. The frame size will not be 7.5 ms or 10 ms, but is scaled + * by 'supported samplerate' / 'input samplerate' + * + * 2. The bandwidth will be hard limited (to 20 KHz) if you select 48 KHz. + * The encoded bandwidth will also be affected by the above inverse + * factor of 20 KHz. + * + * Applied to 44.1 KHz, we get : + * + * 1. About 8.16 ms frame duration, instead of 7.5 ms + * About 10.88 ms frame duration, instead of 10 ms + * + * 2. The bandwidth becomes limited to 18.375 KHz + * + * + * --- How to encode / decode --- + * + * An encoder / decoder context needs to be setup. This context keeps states + * on the current stream to proceed, and samples that overlapped across + * frames. + * + * You have two ways to setup the encoder / decoder : + * + * - Using static memory allocation (this module does not rely on + * any dynamic memory allocation). The types `lc3_xxcoder_mem_16k_t`, + * and `lc3_xxcoder_mem_48k_t` have size of the memory needed for + * encoding up to 16 KHz or 48 KHz. + * + * - Using dynamic memory allocation. The `lc3_xxcoder_size()` procedure + * returns the needed memory size, for a given configuration. The memory + * space must be aligned to a pointer size. As an example, you can setup + * encoder like this : + * + * | enc = lc3_setup_encoder(frame_us, samplerate, + * | malloc(lc3_encoder_size(frame_us, samplerate))); + * | ... + * | free(enc); + * + * Note : + * - A NULL memory adress as input, will return a NULL encoder context. + * - The returned encoder handle is set at the address of the allocated + * memory space, you can directly free the handle. + * + * Next, call the `lc3_encode()` encoding procedure, for each frames. + * To handle multichannel streams (Stereo or more), you can proceed with + * interleaved channels PCM stream like this : + * + * | for(int ich = 0; ich < nch: ich++) + * | lc3_encode(encoder[ich], pcm + ich, nch, ...); + * + * with `nch` as the number of channels in the PCM stream + * + * --- + * + * Antoine SOULIER, Tempow / Google LLC + * + */ + +#ifndef __LC3_H +#define __LC3_H + +#ifdef __cplusplus +extern "C" { +#endif + +#include +#include + +#include "lc3_private.h" + + +/** + * Limitations + * - On the bitrate, in bps, of a stream + * - On the size of the frames in bytes + * - On the number of samples by frames + */ + +#define LC3_MIN_BITRATE 16000 +#define LC3_MAX_BITRATE 320000 + +#define LC3_MIN_FRAME_BYTES 20 +#define LC3_MAX_FRAME_BYTES 400 + +#define LC3_MIN_FRAME_SAMPLES __LC3_NS( 7500, 8000) +#define LC3_MAX_FRAME_SAMPLES __LC3_NS(10000, 48000) + + +/** + * Parameters check + * LC3_CHECK_DT_US(us) True when frame duration in us is suitable + * LC3_CHECK_SR_HZ(sr) True when samplerate in Hz is suitable + */ + +#define LC3_CHECK_DT_US(us) \ + ( ((us) == 7500) || ((us) == 10000) ) + +#define LC3_CHECK_SR_HZ(sr) \ + ( ((sr) == 8000) || ((sr) == 16000) || ((sr) == 24000) || \ + ((sr) == 32000) || ((sr) == 48000) ) + + +/** + * PCM Sample Format + * S16 Signed 16 bits, in 16 bits words (int16_t) + * S24 Signed 24 bits, using low three bytes of 32 bits words (int32_t). + * The high byte sign extends (bits 31..24 set to b23). + * S24_3LE Signed 24 bits packed in 3 bytes little endian + * FLOAT Floating point 32 bits (float type), in range -1 to 1 + */ + +enum lc3_pcm_format { + LC3_PCM_FORMAT_S16, + LC3_PCM_FORMAT_S24, + LC3_PCM_FORMAT_S24_3LE, + LC3_PCM_FORMAT_FLOAT, +}; + + +/** + * Handle + */ + +typedef struct lc3_encoder *lc3_encoder_t; +typedef struct lc3_decoder *lc3_decoder_t; + + +/** + * Static memory of encoder context + * + * Propose types suitable for static memory allocation, supporting + * any frame duration, and maximum samplerates 16k and 48k respectively + * You can customize your type using the `LC3_ENCODER_MEM_T` or + * `LC3_DECODER_MEM_T` macro. + */ + +typedef LC3_ENCODER_MEM_T(10000, 16000) lc3_encoder_mem_16k_t; +typedef LC3_ENCODER_MEM_T(10000, 48000) lc3_encoder_mem_48k_t; + +typedef LC3_DECODER_MEM_T(10000, 16000) lc3_decoder_mem_16k_t; +typedef LC3_DECODER_MEM_T(10000, 48000) lc3_decoder_mem_48k_t; + + +/** + * Return the number of PCM samples in a frame + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * return Number of PCM samples, -1 on bad parameters + */ +int lc3_frame_samples(int dt_us, int sr_hz); + +/** + * Return the size of frames, from bitrate + * dt_us Frame duration in us, 7500 or 10000 + * bitrate Target bitrate in bit per second + * return The floor size in bytes of the frames, -1 on bad parameters + */ +int lc3_frame_bytes(int dt_us, int bitrate); + +/** + * Resolve the bitrate, from the size of frames + * dt_us Frame duration in us, 7500 or 10000 + * nbytes Size in bytes of the frames + * return The according bitrate in bps, -1 on bad parameters + */ +int lc3_resolve_bitrate(int dt_us, int nbytes); + +/** + * Return algorithmic delay, as a number of samples + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * return Number of algorithmic delay samples, -1 on bad parameters + */ +int lc3_delay_samples(int dt_us, int sr_hz); + +/** + * Return size needed for an encoder + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * return Size of then encoder in bytes, 0 on bad parameters + * + * The `sr_hz` parameter is the samplerate of the PCM input stream, + * and will match `sr_pcm_hz` of `lc3_setup_encoder()`. + */ +unsigned lc3_encoder_size(int dt_us, int sr_hz); + +/** + * Setup encoder + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * sr_pcm_hz Input samplerate, downsampling option of input, or 0 + * mem Encoder memory space, aligned to pointer type + * return Encoder as an handle, NULL on bad parameters + * + * The `sr_pcm_hz` parameter is a downsampling option of PCM input, + * the value `0` fallback to the samplerate of the encoded stream `sr_hz`. + * When used, `sr_pcm_hz` is intended to be higher or equal to the encoder + * samplerate `sr_hz`.

It does not rely on any bit reservoir, + * a frame will be strictly encoded in the bytes budget given by + * the user (or transport layer). + * + * However, the bitrate (bytes budget for encoding a frame) can be + * freely changed at any time. But will not rely on signal complexity, + * it can follow a temporary bandwidth increase or reduction. + * + * - Unlike classic codecs, the LC3 codecs does not run on fixed amount + * of samples as input. It operates only on fixed frame duration, for + * any supported samplerates (8 to 48 KHz). Two frames duration are + * available 7.5ms and 10ms. + * + * + * --- About 44.1 KHz samplerate --- + * + * The Bluetooth specification reference the 44.1 KHz samplerate, although + * there is no support in the core algorithm of the codec of 44.1 KHz. + * We can summarize the 44.1 KHz support by "you can put any samplerate + * around the defined base samplerates". Please mind the following items : + * + * 1. The frame size will not be 7.5 ms or 10 ms, but is scaled + * by 'supported samplerate' / 'input samplerate' + * + * 2. The bandwidth will be hard limited (to 20 KHz) if you select 48 KHz. + * The encoded bandwidth will also be affected by the above inverse + * factor of 20 KHz. + * + * Applied to 44.1 KHz, we get : + * + * 1. About 8.16 ms frame duration, instead of 7.5 ms + * About 10.88 ms frame duration, instead of 10 ms + * + * 2. The bandwidth becomes limited to 18.375 KHz + * + * + * --- How to encode / decode --- + * + * An encoder / decoder context needs to be setup. This context keeps states + * on the current stream to proceed, and samples that overlapped across + * frames. + * + * You have two ways to setup the encoder / decoder : + * + * - Using static memory allocation (this module does not rely on + * any dynamic memory allocation). The types `lc3_xxcoder_mem_16k_t`, + * and `lc3_xxcoder_mem_48k_t` have size of the memory needed for + * encoding up to 16 KHz or 48 KHz. + * + * - Using dynamic memory allocation. The `lc3_xxcoder_size()` procedure + * returns the needed memory size, for a given configuration. The memory + * space must be aligned to a pointer size. As an example, you can setup + * encoder like this : + * + * | enc = lc3_setup_encoder(frame_us, samplerate, + * | malloc(lc3_encoder_size(frame_us, samplerate))); + * | ... + * | free(enc); + * + * Note : + * - A NULL memory adress as input, will return a NULL encoder context. + * - The returned encoder handle is set at the address of the allocated + * memory space, you can directly free the handle. + * + * Next, call the `lc3_encode()` encoding procedure, for each frames. + * To handle multichannel streams (Stereo or more), you can proceed with + * interleaved channels PCM stream like this : + * + * | for(int ich = 0; ich < nch: ich++) + * | lc3_encode(encoder[ich], pcm + ich, nch, ...); + * + * with `nch` as the number of channels in the PCM stream + * + * --- + * + * Antoine SOULIER, Tempow / Google LLC + * + */ + +#ifndef __LC3_H +#define __LC3_H + +#ifdef __cplusplus +extern "C" { +#endif + +#include +#include + +#include "lc3_private.h" + + +/** + * Limitations + * - On the bitrate, in bps, of a stream + * - On the size of the frames in bytes + * - On the number of samples by frames + */ + +#define LC3_MIN_BITRATE 16000 +#define LC3_MAX_BITRATE 320000 + +#define LC3_MIN_FRAME_BYTES 20 +#define LC3_MAX_FRAME_BYTES 400 + +#define LC3_MIN_FRAME_SAMPLES __LC3_NS( 7500, 8000) +#define LC3_MAX_FRAME_SAMPLES __LC3_NS(10000, 48000) + + +/** + * Parameters check + * LC3_CHECK_DT_US(us) True when frame duration in us is suitable + * LC3_CHECK_SR_HZ(sr) True when samplerate in Hz is suitable + */ + +#define LC3_CHECK_DT_US(us) \ + ( ((us) == 7500) || ((us) == 10000) ) + +#define LC3_CHECK_SR_HZ(sr) \ + ( ((sr) == 8000) || ((sr) == 16000) || ((sr) == 24000) || \ + ((sr) == 32000) || ((sr) == 48000) ) + + +/** + * PCM Sample Format + * S16 Signed 16 bits, in 16 bits words (int16_t) + * S24 Signed 24 bits, using low three bytes of 32 bits words (int32_t). + * The high byte sign extends (bits 31..24 set to b23). + * S24_3LE Signed 24 bits packed in 3 bytes little endian + * FLOAT Floating point 32 bits (float type), in range -1 to 1 + */ + +enum lc3_pcm_format { + LC3_PCM_FORMAT_S16, + LC3_PCM_FORMAT_S24, + LC3_PCM_FORMAT_S24_3LE, + LC3_PCM_FORMAT_FLOAT, +}; + + +/** + * Handle + */ + +typedef struct lc3_encoder *lc3_encoder_t; +typedef struct lc3_decoder *lc3_decoder_t; + + +/** + * Static memory of encoder context + * + * Propose types suitable for static memory allocation, supporting + * any frame duration, and maximum samplerates 16k and 48k respectively + * You can customize your type using the `LC3_ENCODER_MEM_T` or + * `LC3_DECODER_MEM_T` macro. + */ + +typedef LC3_ENCODER_MEM_T(10000, 16000) lc3_encoder_mem_16k_t; +typedef LC3_ENCODER_MEM_T(10000, 48000) lc3_encoder_mem_48k_t; + +typedef LC3_DECODER_MEM_T(10000, 16000) lc3_decoder_mem_16k_t; +typedef LC3_DECODER_MEM_T(10000, 48000) lc3_decoder_mem_48k_t; + + +/** + * Return the number of PCM samples in a frame + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * return Number of PCM samples, -1 on bad parameters + */ +int lc3_frame_samples(int dt_us, int sr_hz); + +/** + * Return the size of frames, from bitrate + * dt_us Frame duration in us, 7500 or 10000 + * bitrate Target bitrate in bit per second + * return The floor size in bytes of the frames, -1 on bad parameters + */ +int lc3_frame_bytes(int dt_us, int bitrate); + +/** + * Resolve the bitrate, from the size of frames + * dt_us Frame duration in us, 7500 or 10000 + * nbytes Size in bytes of the frames + * return The according bitrate in bps, -1 on bad parameters + */ +int lc3_resolve_bitrate(int dt_us, int nbytes); + +/** + * Return algorithmic delay, as a number of samples + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * return Number of algorithmic delay samples, -1 on bad parameters + */ +int lc3_delay_samples(int dt_us, int sr_hz); + +/** + * Return size needed for an encoder + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * return Size of then encoder in bytes, 0 on bad parameters + * + * The `sr_hz` parameter is the samplerate of the PCM input stream, + * and will match `sr_pcm_hz` of `lc3_setup_encoder()`. + */ +unsigned lc3_encoder_size(int dt_us, int sr_hz); + +/** + * Setup encoder + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * sr_pcm_hz Input samplerate, downsampling option of input, or 0 + * mem Encoder memory space, aligned to pointer type + * return Encoder as an handle, NULL on bad parameters + * + * The `sr_pcm_hz` parameter is a downsampling option of PCM input, + * the value `0` fallback to the samplerate of the encoded stream `sr_hz`. + * When used, `sr_pcm_hz` is intended to be higher or equal to the encoder + * samplerate `sr_hz`.

It does not rely on any bit reservoir, - * a frame will be strictly encoded in the bytes budget given by - * the user (or transport layer). - * - * However, the bitrate (bytes budget for encoding a frame) can be - * freely changed at any time. But will not rely on signal complexity, - * it can follow a temporary bandwidth increase or reduction. - * - * - Unlike classic codecs, the LC3 codecs does not run on fixed amount - * of samples as input. It operates only on fixed frame duration, for - * any supported samplerates (8 to 48 KHz). Two frames duration are - * available 7.5ms and 10ms. - * - * - * --- About 44.1 KHz samplerate --- - * - * The Bluetooth specification reference the 44.1 KHz samplerate, although - * there is no support in the core algorithm of the codec of 44.1 KHz. - * We can summarize the 44.1 KHz support by "you can put any samplerate - * around the defined base samplerates". Please mind the following items : - * - * 1. The frame size will not be 7.5 ms or 10 ms, but is scaled - * by 'supported samplerate' / 'input samplerate' - * - * 2. The bandwidth will be hard limited (to 20 KHz) if you select 48 KHz. - * The encoded bandwidth will also be affected by the above inverse - * factor of 20 KHz. - * - * Applied to 44.1 KHz, we get : - * - * 1. About 8.16 ms frame duration, instead of 7.5 ms - * About 10.88 ms frame duration, instead of 10 ms - * - * 2. The bandwidth becomes limited to 18.375 KHz - * - * - * --- How to encode / decode --- - * - * An encoder / decoder context needs to be setup. This context keeps states - * on the current stream to proceed, and samples that overlapped across - * frames. - * - * You have two ways to setup the encoder / decoder : - * - * - Using static memory allocation (this module does not rely on - * any dynamic memory allocation). The types `lc3_xxcoder_mem_16k_t`, - * and `lc3_xxcoder_mem_48k_t` have size of the memory needed for - * encoding up to 16 KHz or 48 KHz. - * - * - Using dynamic memory allocation. The `lc3_xxcoder_size()` procedure - * returns the needed memory size, for a given configuration. The memory - * space must be aligned to a pointer size. As an example, you can setup - * encoder like this : - * - * | enc = lc3_setup_encoder(frame_us, samplerate, - * | malloc(lc3_encoder_size(frame_us, samplerate))); - * | ... - * | free(enc); - * - * Note : - * - A NULL memory adress as input, will return a NULL encoder context. - * - The returned encoder handle is set at the address of the allocated - * memory space, you can directly free the handle. - * - * Next, call the `lc3_encode()` encoding procedure, for each frames. - * To handle multichannel streams (Stereo or more), you can proceed with - * interleaved channels PCM stream like this : - * - * | for(int ich = 0; ich < nch: ich++) - * | lc3_encode(encoder[ich], pcm + ich, nch, ...); - * - * with `nch` as the number of channels in the PCM stream - * - * --- - * - * Antoine SOULIER, Tempow / Google LLC - * - */ - -#ifndef __LC3_H -#define __LC3_H - -#ifdef __cplusplus -extern "C" { -#endif - -#include -#include - -#include "lc3_private.h" - - -/** - * Limitations - * - On the bitrate, in bps, of a stream - * - On the size of the frames in bytes - * - On the number of samples by frames - */ - -#define LC3_MIN_BITRATE 16000 -#define LC3_MAX_BITRATE 320000 - -#define LC3_MIN_FRAME_BYTES 20 -#define LC3_MAX_FRAME_BYTES 400 - -#define LC3_MIN_FRAME_SAMPLES __LC3_NS( 7500, 8000) -#define LC3_MAX_FRAME_SAMPLES __LC3_NS(10000, 48000) - - -/** - * Parameters check - * LC3_CHECK_DT_US(us) True when frame duration in us is suitable - * LC3_CHECK_SR_HZ(sr) True when samplerate in Hz is suitable - */ - -#define LC3_CHECK_DT_US(us) \ - ( ((us) == 7500) || ((us) == 10000) ) - -#define LC3_CHECK_SR_HZ(sr) \ - ( ((sr) == 8000) || ((sr) == 16000) || ((sr) == 24000) || \ - ((sr) == 32000) || ((sr) == 48000) ) - - -/** - * PCM Sample Format - * S16 Signed 16 bits, in 16 bits words (int16_t) - * S24 Signed 24 bits, using low three bytes of 32 bits words (int32_t). - * The high byte sign extends (bits 31..24 set to b23). - * S24_3LE Signed 24 bits packed in 3 bytes little endian - * FLOAT Floating point 32 bits (float type), in range -1 to 1 - */ - -enum lc3_pcm_format { - LC3_PCM_FORMAT_S16, - LC3_PCM_FORMAT_S24, - LC3_PCM_FORMAT_S24_3LE, - LC3_PCM_FORMAT_FLOAT, -}; - - -/** - * Handle - */ - -typedef struct lc3_encoder *lc3_encoder_t; -typedef struct lc3_decoder *lc3_decoder_t; - - -/** - * Static memory of encoder context - * - * Propose types suitable for static memory allocation, supporting - * any frame duration, and maximum samplerates 16k and 48k respectively - * You can customize your type using the `LC3_ENCODER_MEM_T` or - * `LC3_DECODER_MEM_T` macro. - */ - -typedef LC3_ENCODER_MEM_T(10000, 16000) lc3_encoder_mem_16k_t; -typedef LC3_ENCODER_MEM_T(10000, 48000) lc3_encoder_mem_48k_t; - -typedef LC3_DECODER_MEM_T(10000, 16000) lc3_decoder_mem_16k_t; -typedef LC3_DECODER_MEM_T(10000, 48000) lc3_decoder_mem_48k_t; - - -/** - * Return the number of PCM samples in a frame - * dt_us Frame duration in us, 7500 or 10000 - * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 - * return Number of PCM samples, -1 on bad parameters - */ -int lc3_frame_samples(int dt_us, int sr_hz); - -/** - * Return the size of frames, from bitrate - * dt_us Frame duration in us, 7500 or 10000 - * bitrate Target bitrate in bit per second - * return The floor size in bytes of the frames, -1 on bad parameters - */ -int lc3_frame_bytes(int dt_us, int bitrate); - -/** - * Resolve the bitrate, from the size of frames - * dt_us Frame duration in us, 7500 or 10000 - * nbytes Size in bytes of the frames - * return The according bitrate in bps, -1 on bad parameters - */ -int lc3_resolve_bitrate(int dt_us, int nbytes); - -/** - * Return algorithmic delay, as a number of samples - * dt_us Frame duration in us, 7500 or 10000 - * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 - * return Number of algorithmic delay samples, -1 on bad parameters - */ -int lc3_delay_samples(int dt_us, int sr_hz); - -/** - * Return size needed for an encoder - * dt_us Frame duration in us, 7500 or 10000 - * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 - * return Size of then encoder in bytes, 0 on bad parameters - * - * The `sr_hz` parameter is the samplerate of the PCM input stream, - * and will match `sr_pcm_hz` of `lc3_setup_encoder()`. - */ -unsigned lc3_encoder_size(int dt_us, int sr_hz); - -/** - * Setup encoder - * dt_us Frame duration in us, 7500 or 10000 - * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 - * sr_pcm_hz Input samplerate, downsampling option of input, or 0 - * mem Encoder memory space, aligned to pointer type - * return Encoder as an handle, NULL on bad parameters - * - * The `sr_pcm_hz` parameter is a downsampling option of PCM input, - * the value `0` fallback to the samplerate of the encoded stream `sr_hz`. - * When used, `sr_pcm_hz` is intended to be higher or equal to the encoder - * samplerate `sr_hz`.

From 964323880772ccccbd41835ff45c074fc228d981 Mon Sep 17 00:00:00 2001 From: Art Jiang Date: Thu, 6 Nov 2025 21:39:37 -0800 Subject: [PATCH 98/99] Epic/2 ai integration (#16) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * prompt(architecture): Clean slate refactoring - remove complex state management WHAT: Remove AppStateProvider god object, service locator pattern, and complex UI hierarchy to implement clean direct service-to-UI communication architecture WHY: The previous architecture had become over-engineered with a 428-line AppStateProvider managing all state, service locator pattern creating hidden dependencies, and 1000+ line UI components violating single responsibility principle. This complexity was causing bugs, making the app hard to maintain, and preventing incremental feature development HOW: Deleted all complex state management components including AppStateProvider, ServiceLocator, and multi-responsibility UI widgets. Removed unnecessary services and models not needed for core audio functionality. This creates a clean foundation where services own their data and UI components directly consume service streams without intermediary coordinators * prompt(audio): Implement minimal working audio foundation with direct service integration WHAT: Create minimal Flutter app with working audio recording, real-time timer, audio level visualization, and file management using direct service-to-UI communication WHY: Prove that simple architecture works better than complex state management by building incrementally from a clean foundation. Each feature must work before adding the next, ensuring the app is always functional and eliminating the bugs caused by over-engineering HOW: Implemented RecordingScreen as a simple StatefulWidget that directly integrates with AudioServiceImpl streams for real-time updates. Added timer display consuming recordingDurationStream, audio level indicator consuming audioLevelStream, and FileManagementScreen for playback. No state managers, no service locators, just direct data flow from service to UI via Dart streams * prompt(ios): Simplify iOS configuration and remove unnecessary dependencies WHAT: Clean up iOS configuration to only include essential permissions and reduce Flutter dependencies to minimum required for audio recording WHY: The app was crashing on device due to complex permission configurations and unnecessary dependencies. Too many permissions (Bluetooth, Speech, Location) were causing initialization failures when only microphone permission was needed for basic audio recording HOW: Simplified Info.plist to only request microphone permission, cleaned Podfile to remove unused permission handlers, and reduced pubspec.yaml dependencies to only flutter_sound, permission_handler, and freezed for data models. This eliminates potential permission-related crashes and reduces app complexity * prompt(docs): Update documentation to reflect proven clean architecture approach * Architecture.md - Documents actual implemented patterns: - Direct service-to-UI communication via StatefulWidget + Streams - Eliminates complex state management (AppStateProvider removed) - Phase 1 completion proven with working audio foundation * TechnicalSpecs.md - Updated with real Dart/Flutter implementation: - Concrete code examples from actual working implementation - flutter_sound integration patterns - StatefulWidget with StreamSubscription approach * SLA.md - Changed from service uptime to development process SLA: - Phase delivery schedule with Phase 1 marked complete - Quality gates for each incremental step - Proven audio foundation as baseline for future phases * README.md - Updated to reflect current minimal dependencies: - Removed references to complex state management - Updated project structure to match clean implementation - Simplified setup instructions These docs now accurately represent the working foundation built following Linus Torvalds principles: good taste, simplicity, elimination of special cases, and clear data ownership. * feat: add G1 integration with LC3 codec and BLE services * feat: add LC3 codec implementation with core audio processing modules * WORKING EDITION feat: implement Bluetooth and speech recognition functionality for iOS * Working Edition * feat: add iOS deployment target and bluetooth debugging documentation * Logo and screen modifications for better UI * feat: add iOS and macOS app configurations with Flutter sound integration * Remoevd redudancy * feat(models): add core data models with Freezed for Phase 1.1 Implement immutable data models following "Good Taste" principles: - Data structures define architecture - Clear ownership and lifecycle - Comprehensive test coverage Models added: - GlassesConnection: BLE connection state with battery/quality - ConversationSession: Recording session with transcript segments - TranscriptSegment: Individual speech recognition results - AudioChunk: Audio data with duration calculation All models include: - Freezed immutable classes with copyWith - JSON serialization (requires code generation) - Factory constructors for common states - Extension methods for computed properties Tests provide 100% coverage: - Serialization/deserialization - Factory constructors - Extension methods - Edge cases This establishes the data structure foundation for the entire application. Services and UI will build on these models.

It does not rely on any bit reservoir, + * a frame will be strictly encoded in the bytes budget given by + * the user (or transport layer). + * + * However, the bitrate (bytes budget for encoding a frame) can be + * freely changed at any time. But will not rely on signal complexity, + * it can follow a temporary bandwidth increase or reduction. + * + * - Unlike classic codecs, the LC3 codecs does not run on fixed amount + * of samples as input. It operates only on fixed frame duration, for + * any supported samplerates (8 to 48 KHz). Two frames duration are + * available 7.5ms and 10ms. + * + * + * --- About 44.1 KHz samplerate --- + * + * The Bluetooth specification reference the 44.1 KHz samplerate, although + * there is no support in the core algorithm of the codec of 44.1 KHz. + * We can summarize the 44.1 KHz support by "you can put any samplerate + * around the defined base samplerates". Please mind the following items : + * + * 1. The frame size will not be 7.5 ms or 10 ms, but is scaled + * by 'supported samplerate' / 'input samplerate' + * + * 2. The bandwidth will be hard limited (to 20 KHz) if you select 48 KHz. + * The encoded bandwidth will also be affected by the above inverse + * factor of 20 KHz. + * + * Applied to 44.1 KHz, we get : + * + * 1. About 8.16 ms frame duration, instead of 7.5 ms + * About 10.88 ms frame duration, instead of 10 ms + * + * 2. The bandwidth becomes limited to 18.375 KHz + * + * + * --- How to encode / decode --- + * + * An encoder / decoder context needs to be setup. This context keeps states + * on the current stream to proceed, and samples that overlapped across + * frames. + * + * You have two ways to setup the encoder / decoder : + * + * - Using static memory allocation (this module does not rely on + * any dynamic memory allocation). The types `lc3_xxcoder_mem_16k_t`, + * and `lc3_xxcoder_mem_48k_t` have size of the memory needed for + * encoding up to 16 KHz or 48 KHz. + * + * - Using dynamic memory allocation. The `lc3_xxcoder_size()` procedure + * returns the needed memory size, for a given configuration. The memory + * space must be aligned to a pointer size. As an example, you can setup + * encoder like this : + * + * | enc = lc3_setup_encoder(frame_us, samplerate, + * | malloc(lc3_encoder_size(frame_us, samplerate))); + * | ... + * | free(enc); + * + * Note : + * - A NULL memory adress as input, will return a NULL encoder context. + * - The returned encoder handle is set at the address of the allocated + * memory space, you can directly free the handle. + * + * Next, call the `lc3_encode()` encoding procedure, for each frames. + * To handle multichannel streams (Stereo or more), you can proceed with + * interleaved channels PCM stream like this : + * + * | for(int ich = 0; ich < nch: ich++) + * | lc3_encode(encoder[ich], pcm + ich, nch, ...); + * + * with `nch` as the number of channels in the PCM stream + * + * --- + * + * Antoine SOULIER, Tempow / Google LLC + * + */ + +#ifndef __LC3_H +#define __LC3_H + +#ifdef __cplusplus +extern "C" { +#endif + +#include +#include + +#include "lc3_private.h" + + +/** + * Limitations + * - On the bitrate, in bps, of a stream + * - On the size of the frames in bytes + * - On the number of samples by frames + */ + +#define LC3_MIN_BITRATE 16000 +#define LC3_MAX_BITRATE 320000 + +#define LC3_MIN_FRAME_BYTES 20 +#define LC3_MAX_FRAME_BYTES 400 + +#define LC3_MIN_FRAME_SAMPLES __LC3_NS( 7500, 8000) +#define LC3_MAX_FRAME_SAMPLES __LC3_NS(10000, 48000) + + +/** + * Parameters check + * LC3_CHECK_DT_US(us) True when frame duration in us is suitable + * LC3_CHECK_SR_HZ(sr) True when samplerate in Hz is suitable + */ + +#define LC3_CHECK_DT_US(us) \ + ( ((us) == 7500) || ((us) == 10000) ) + +#define LC3_CHECK_SR_HZ(sr) \ + ( ((sr) == 8000) || ((sr) == 16000) || ((sr) == 24000) || \ + ((sr) == 32000) || ((sr) == 48000) ) + + +/** + * PCM Sample Format + * S16 Signed 16 bits, in 16 bits words (int16_t) + * S24 Signed 24 bits, using low three bytes of 32 bits words (int32_t). + * The high byte sign extends (bits 31..24 set to b23). + * S24_3LE Signed 24 bits packed in 3 bytes little endian + * FLOAT Floating point 32 bits (float type), in range -1 to 1 + */ + +enum lc3_pcm_format { + LC3_PCM_FORMAT_S16, + LC3_PCM_FORMAT_S24, + LC3_PCM_FORMAT_S24_3LE, + LC3_PCM_FORMAT_FLOAT, +}; + + +/** + * Handle + */ + +typedef struct lc3_encoder *lc3_encoder_t; +typedef struct lc3_decoder *lc3_decoder_t; + + +/** + * Static memory of encoder context + * + * Propose types suitable for static memory allocation, supporting + * any frame duration, and maximum samplerates 16k and 48k respectively + * You can customize your type using the `LC3_ENCODER_MEM_T` or + * `LC3_DECODER_MEM_T` macro. + */ + +typedef LC3_ENCODER_MEM_T(10000, 16000) lc3_encoder_mem_16k_t; +typedef LC3_ENCODER_MEM_T(10000, 48000) lc3_encoder_mem_48k_t; + +typedef LC3_DECODER_MEM_T(10000, 16000) lc3_decoder_mem_16k_t; +typedef LC3_DECODER_MEM_T(10000, 48000) lc3_decoder_mem_48k_t; + + +/** + * Return the number of PCM samples in a frame + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * return Number of PCM samples, -1 on bad parameters + */ +int lc3_frame_samples(int dt_us, int sr_hz); + +/** + * Return the size of frames, from bitrate + * dt_us Frame duration in us, 7500 or 10000 + * bitrate Target bitrate in bit per second + * return The floor size in bytes of the frames, -1 on bad parameters + */ +int lc3_frame_bytes(int dt_us, int bitrate); + +/** + * Resolve the bitrate, from the size of frames + * dt_us Frame duration in us, 7500 or 10000 + * nbytes Size in bytes of the frames + * return The according bitrate in bps, -1 on bad parameters + */ +int lc3_resolve_bitrate(int dt_us, int nbytes); + +/** + * Return algorithmic delay, as a number of samples + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * return Number of algorithmic delay samples, -1 on bad parameters + */ +int lc3_delay_samples(int dt_us, int sr_hz); + +/** + * Return size needed for an encoder + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * return Size of then encoder in bytes, 0 on bad parameters + * + * The `sr_hz` parameter is the samplerate of the PCM input stream, + * and will match `sr_pcm_hz` of `lc3_setup_encoder()`. + */ +unsigned lc3_encoder_size(int dt_us, int sr_hz); + +/** + * Setup encoder + * dt_us Frame duration in us, 7500 or 10000 + * sr_hz Samplerate in Hz, 8000, 16000, 24000, 32000 or 48000 + * sr_pcm_hz Input samplerate, downsampling option of input, or 0 + * mem Encoder memory space, aligned to pointer type + * return Encoder as an handle, NULL on bad parameters + * + * The `sr_pcm_hz` parameter is a downsampling option of PCM input, + * the value `0` fallback to the samplerate of the encoded stream `sr_hz`. + * When used, `sr_pcm_hz` is intended to be higher or equal to the encoder + * samplerate `sr_hz`.
