Changed level calculation from RMS to peak detection to show more realistic and responsive meter values. The Problem: - RMS calculation produced values typically in 0-30% range - Audio signals have low average RMS (0.1-0.3 for music) - Meters appeared broken, never reaching higher levels The Solution: - Switched to peak detection (max absolute value) - Peaks now properly show 0-100% range - More responsive to transients and dynamics - Matches typical DAW meter behavior Algorithm Change: Before (RMS): rms = sqrt(sum(normalized²) / length) After (Peak): peak = max(abs(normalized)) Applied to Both: - Recording input level monitoring (useRecording) - Playback output level monitoring (useMultiTrackPlayer) Benefits: ✅ Full 0-100% range utilization ✅ More responsive visual feedback ✅ Accurate representation of audio peaks ✅ Consistent with professional audio software 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
