-# Audio Peak Measurement Fix Summary
-
-## Issues Found and Fixed
-
-### Issue #1: Peak Measured at Wrong Time (❌ FIXED)
-**Problem:** Peak was measured when audio was written to ring buffer (~400ms before playback), causing visual effects to trigger 400ms early.
-
-**Solution:**
-- Added `get_realtime_peak()` to AudioBackend interface
-- Implemented real-time peak measurement in audio callback when samples are actually played
-- Updated main.cc and test_demo.cc to use `audio_get_realtime_peak()` instead of `synth_get_output_peak()`
-
-**Files Modified:**
-- src/audio/audio_backend.h
-- src/audio/miniaudio_backend.h/cc
-- src/audio/mock_audio_backend.h/cc
-- src/audio/wav_dump_backend.h/cc
-- src/audio/jittered_audio_backend.h/cc
-- src/audio/audio.h/cc
-- src/main.cc
-- src/test_demo.cc
-- src/tests/test_audio_backend.cc
-
-### Issue #2: Peak Decay Too Slow (❌ FIXED)
-**Problem:** Peak decay rate of 0.95 per callback meant visual effects stayed bright for ~6 seconds after a drum hit, causing constant flashing.
-
-**Root Cause Analysis:**
-- Decay rate: 0.95 per callback
-- Callback interval: ~128ms
-- Time to decay to 10%: **~5.76 seconds** (45 callbacks)
-- Result: Screen stays white for 6+ seconds after each drum hit
-
-**Solution:**
-- Changed decay rate from 0.95 to 0.7
-- New decay timing:
-  - 50% intensity: ~256ms (2 callbacks)
-  - 10% intensity: ~1.15 seconds (9 callbacks)
-- Result: Quick flash with smooth fade, proper visual sync
-
-**Decay Comparison:**
-```
-Old (0.95):  ████████████████████████████ (6 seconds to fade)
-New (0.7):   ████ (1 second to fade)
-```
-
-**File Modified:**
-- src/audio/miniaudio_backend.cc (line 164)
-
-## Verification
-
-✅ All 27 tests pass
-✅ demo64k builds successfully
-✅ test_demo builds successfully
-✅ Peak decay timing verified mathematically
-✅ Audio-visual sync should now be accurate
-
-## Testing Instructions
-
-Run test_demo to verify the fix:
-```bash
-./build/test_demo
-```
-
-Expected behavior:
-- Screen should flash white on drum hits (every ~0.5 seconds)
-- Flash should fade quickly (~1 second)
-- No constant white screen
-- Audio and visual should be synchronized
-
-## Known Build Issues (Pre-existing)
-
-The following tests have linker errors (unrelated to peak measurement fix):
-- test_effect_base (missing WebGPUTestFixture)
-- test_post_process_helper (missing main)
-- test_texture_manager (missing main)
-- test_demo_effects (missing main)
-
-These appear to be incomplete test implementations and should be addressed separately.
