Frequently Asked Questions
Is this multi-track audio editor completely free?
Yes, 100% free with no trial limits, subscriptions, or paywalls. All processing runs entirely inside your web browser using modern Web Audio API and WebAssembly.
Does my audio get uploaded to any servers?
No. Your audio files and recordings never leave your device. All playback, DSP effects, waveform generation, and export rendering happen locally on your computer's CPU and GPU.
What is Auto Ducking and how does it work?
Auto Ducking automatically lowers the volume of background music whenever speech or voiceover is detected on another track. It creates clean, broadcast-ready podcasts and video voiceovers without tedious manual automation.
What does non-destructive editing mean?
Non-destructive editing preserves your original audio file completely untouched. Every effect (EQ, noise removal, reverb, pitch change) is applied dynamically as a removable tag. You can turn effects off, adjust parameters, or remove them at any time without degrading the original recording.
Can I save my multi-track session and reopen it later?
Yes. Projects are saved directly into your browser's IndexedDB storage. You can close your tab, return later, and pick up right where you left off, or export a project file for backup.
Which audio export formats are supported?
You can export your final multi-track master mixdown as lossless 16-bit, 24-bit, or 32-bit float WAV, with custom sample rates (44.1 kHz or 48 kHz) in stereo or mono.
