Professional desktop audio editor built with Electron, React, TypeScript, and the Web Audio API.

Version

• Open multiple audio files simultaneously (WAV, MP3, OGG, FLAC, AIFF, AAC)
• Save / Save As / Export as 16-bit WAV
• Native OS file dialogs via Electron IPC

• Multi-track synchronized playback with per-track gain and stereo pan
• Master volume control and real-time level metering (L/R)
• Solo/Mute logic with automatic track routing
• Loop playback support

• Record from microphone via getUserMedia
• WebM/Opus capture with auto-track creation

Apply to a selected region or the entire track:

• AI Voice Removal — Remove vocals from stereo or mono audio using machine learning
  • NMF (Non-negative Matrix Factorization) — Unsupervised learning algorithm that decomposes the spectrogram into vocal and instrumental spectral templates
  • Neural Network Mask Refinement — 3-layer feed-forward network (Dense → ReLU → Dense → Sigmoid) that refines separation masks
  • Mid/Side Coherence Analysis — Stereo field analysis to identify center-panned vocals
  • Accessible from toolbar AI dropdown, right-click context menu, AI menu bar, and Effects panel
  • Progress UI with phase indicators and animated progress bar

Generate Silence, Tones, White Noise, DTMF Tones, and Frequency Sweeps with configurable parameters.

• Copy / Cut / Paste / Delete with AudioBuffer clipboard
• Mix Paste — Insert, Overwrite, or Mix modes with volume, fade, and loop options
• Crossfade — Linear, Equal Power, or S-Curve fade curves
• Split at Cursor, Duplicate, Trim to Selection
• Undo/Redo — Up to 50 levels

• Add, remove, rename, and color-code tracks
• Per-track volume (0–200%) and pan (L100–R100)
• Mute/Solo per track
• Mix Down all tracks into a single stereo track

• Stereo ↔ Mono conversion
• Swap Channels
• Extract Left / Right channel

• Resample to any target rate (presets: 22050 – 192000 Hz)
• Linear interpolation with before/after duration preview

• Frequency Analysis — FFT spectrum analyzer (4096-point, Hann window, averaged)
• Audio Statistics — Peak amplitude, RMS, DC offset, dynamic range, zero crossings, estimated fundamental frequency, crest factor, and more

• Add markers at cursor position with visual pins on the timeline

• Waveform — Min/max envelope with gradient fill
• Spectral — FFT-based spectrogram with color-mapped magnitude
• Split — Waveform + Spectral combined

• Zoom in/out (slider + buttons), Zoom to Selection, Fit to Window
• Auto-scroll during playback with cursor lookahead
• Transport controls: Skip to Start/End, Rewind/Forward ±5s

• Electron — Desktop shell with frameless window
• React 18 — UI components
• TypeScript — Type-safe codebase
• Zustand — State management
• Web Audio API — Audio engine, effects, and analysis
• Vite — Build tooling
• Tailwind CSS — Styling

• Node.js >= 18
• npm
