+# Logging Reduction Implementation Summary
+
+## Changes Made
+
+### 1. AudioService Logging Reduction (`web/src/services/audioService.ts`)
+
+**Change 1: Reduced default log level**
+- **Before**: `private logLevel: LogLevel = LogLevel.WARN;`
+- **After**: `private logLevel: LogLevel = LogLevel.ERROR;`
+- **Impact**: Eliminates all DEBUG, INFO, and WARN logging by default, keeping only ERROR logs
+
+**Change 2: Removed high-frequency event logging**
+- **Before**: DEBUG logging for play, pause, and finish events
+- **After**: No logging for these routine events
+- **Impact**: Eliminates 3 debug log calls per playback state change
+
+### 2. useWaveform Hook Logging Reduction (`web/src/hooks/useWaveform.ts`)
+
+**Changes**: Removed all `console.debug()` calls
+- Removed debug logging for container null checks
+- Removed debug logging for URL validation
+- Removed debug logging for initialization
+- Removed debug logging for audio service usage
+- Removed debug logging for playback state restoration
+- Removed debug logging for cleanup
+- Removed debug logging for play/pause/seek operations
+- **Total removed**: 8 `console.debug()` calls
+- **Impact**: Eliminates all routine debug logging from the waveform hook
+
+## Expected Results
+
+### Before Changes:
+- **AudioService**: DEBUG/INFO/WARN logs for every event (play, pause, finish, audioprocess)
+- **useWaveform**: Multiple console.debug calls for initialization, state changes, and operations
+- **Console spam**: High volume of logging during normal playback
+- **Performance impact**: Console I/O causing UI jank
+
+### After Changes:
+- **AudioService**: Only ERROR-level logs by default (can be adjusted via `setLogLevel()`)
+- **useWaveform**: No debug logging (error logging preserved)
+- **Console output**: Minimal - only errors and critical issues
+- **Performance**: Reduced console I/O overhead, smoother UI
+
+## Debugging Capabilities Preserved
+
+1. **Dynamic log level control**: `audioService.setLogLevel(LogLevel.DEBUG)` can re-enable debugging when needed
+2. **Error logging preserved**: All error logging remains intact
+3. **Reversible changes**: Can easily adjust log levels back if needed
+
+## Testing Recommendations
+
+1. **Playback test**: Load a song and verify no debug logs appear in console
+2. **State change test**: Play, pause, seek - should not produce debug logs
+3. **Error test**: Force an error condition to verify ERROR logs still work
+4. **Debug mode test**: Use `setLogLevel(LogLevel.DEBUG)` to verify debugging can be re-enabled
+
+## Files Modified
+
+- `web/src/services/audioService.ts` - Reduced log level and removed event logging
+- `web/src/hooks/useWaveform.ts` - Removed all console.debug calls
+
+## Risk Assessment
+
+- **Risk Level**: Low
+- **Reversibility**: High (can easily change log levels back)
+- **Functional Impact**: None (logging-only changes)
+- **Performance Impact**: Positive (reduced console overhead)
