📄 Description

Add FLAC Audio Quality Analyzer with Spectrum Visualization

🎯 What's New

Audio quality analyzer that verifies true lossless quality of FLAC files with detailed technical metrics and frequency spectrum visualization.

Key Features:

📊 Technical analysis: sample rate, bit depth, channels, dynamic range, peak/RMS levels
🎨 Real-time spectrogram with enhanced color gradient visualization
🔍 Support for 44.1kHz to 384kHz+ sample rates
💾 File selection dialog integrated into header

🔧 Technical Details

Backend:

Custom FFT implementation (Cooley-Tukey, 8192 samples, Hann windowing)
New files: backend/analysis.go, backend/spectrum.go
Efficient processing: 10M sample limit for memory optimization

Frontend:

New components: AudioAnalysisDialog, AudioAnalysis, SpectrumVisualization
Canvas-based 1600x800 spectrogram with dynamic frequency scaling
Custom useAudioAnalysis hook for state management

📦 Dependencies

Added: github.com/mewkiz/flac v1.0.13
Auto-resolved: icza/bitio, mewkiz/pkg, mewpkg/term

📝 Files Changed

Added: 7 files (~1025 lines)
Modified: app.go, backend/folder.go, Header.tsx, types/api.ts

Parent: ddf1844 (v6.2)
