Multi-Track DAW

A fully client-side digital audio workstation & reverse speech playground. Record, upload, trim, denoise, reverse, play-along, and mixdown up to four stereo tracks — all in the browser with no server round-trips.

Features

Record.* Arm a track by clicking its red dot, then hit Rec. A VU meter shows live levels. Upload.* Click the folder icon on a track, or drag-and-drop audio files onto the DAW. Play-along.* Arm a track and record while playing back existing tracks — perfect for overdubs. Trim.* Use the trim sliders to set start and end points. Waveform shows trim markers in yellow. Denoise.* Click DN to apply noise gating on a track. Quiet samples below the noise floor are suppressed. Reverse.* Click the reverse button to flip a clip backwards. Orange waveform indicates reversed. Mute / Solo.* Mute silences a track. Solo isolates one or more tracks while muting all others. Mixdown.* Click Mixdown to collapse all unmuted tracks into a stereo WAV, normalized to prevent clipping. Download triggers automatically. BPM.* Set the tempo (used as a reference for recording timing — metronome support planned). Clear All.* Wipes all tracks and resets to two fresh stereo tracks.

Usage

1. Arm a track (click 🔴), hit Rec, and record your first take. 2. Upload or drag audio files onto empty tracks. 3. Adjust volume, pan, and trim per track. 4. Hit Play to hear the mix. Arm another track and record while playing to layer parts. 5. Press Stop, then Mixdown to export as WAV.
