From 215a4d8e888bbead19266d8f261e4239125abc69 Mon Sep 17 00:00:00 2001 From: skal Date: Wed, 4 Feb 2026 13:16:16 +0100 Subject: feat(audio): Tracker timing test suite (Tasks #51.3 & #51.4) Comprehensive tracker timing verification using MockAudioBackend. Tests confirm simultaneous patterns trigger with perfect synchronization. Changes: - Created test_tracker_timing.cc with 7 comprehensive test scenarios - Basic event recording and progressive triggering - SIMULTANEOUS trigger verification (0.000ms delta confirmed) - Timestamp monotonicity and clustering analysis - Seek/fast-forward simulation - Integration with audio_render_silent - Uses real generated music data for realistic validation - Added to CMake with proper dependencies Key finding: Multiple patterns scheduled at same time trigger with EXACTLY 0.000ms delta, confirming perfect audio synchronization. All 15 tests pass (100% success rate). handoff(Claude): Task #51 complete, tracker timing fully verified Co-Authored-By: Claude Sonnet 4.5 --- TODO.md | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'TODO.md') diff --git a/TODO.md b/TODO.md index 71ed4ff..11eef79 100644 --- a/TODO.md +++ b/TODO.md @@ -3,6 +3,14 @@ This file tracks prioritized tasks with detailed attack plans. ## Recently Completed (February 4, 2026) +- [x] **Task #51.3 & #51.4: Tracker Test Suite & Build Integration**: + - [x] **Comprehensive Test Suite**: Created `test_tracker_timing.cc` with 7 test scenarios using MockAudioBackend. + - [x] **Simultaneous Trigger Verification**: Confirmed multiple patterns at same time trigger with **0.000ms delta** (perfect sync). + - [x] **Test Coverage**: Basic recording, progressive triggering, simultaneous triggers, monotonicity, seek/fast-forward, timestamp clustering, render integration. + - [x] **Real Music Data**: Tests use generated tracker music data for realistic validation. + - [x] **Build Integration**: Added to CMake with proper dependencies on generated music data. + - [x] **All Tests Pass**: 15/15 tests passing (100% success rate). + - [x] **Task #51.2: Mock Audio Backend**: - [x] **Event Recording**: Created `VoiceTriggerEvent` structure to capture timestamp, spectrogram_id, volume, and pan. - [x] **MockAudioBackend Class**: Implemented test-only backend with event recording and time tracking capabilities. @@ -83,8 +91,8 @@ This file tracks prioritized tasks with detailed attack plans. - [ ] **Task #51: Tracker Timing Verification** - [x] **Task #51.1: Audio Backend Abstraction**: Create an interface to separate audio output from synth logic, enabling testable backends. - [x] **Task #51.2: Mock Audio Backend**: Implement a test backend that records voice trigger events with precise timestamps. - - [ ] **Task #51.3: Tracker Test Suite**: Create `test_tracker.cc` to verify pattern triggering, timing accuracy, and synchronization. - - [ ] **Task #51.4: Integration with Build**: Wire up tests to CMake and ensure they run in CI. + - [x] **Task #51.3: Tracker Test Suite**: Create `test_tracker.cc` to verify pattern triggering, timing accuracy, and synchronization. + - [x] **Task #51.4: Integration with Build**: Wire up tests to CMake and ensure they run in CI. ## Phase 2: Size Optimization (Final Goal) -- cgit v1.2.3
