AudioMass
A real waveform audio editor with zero install and zero upload.
AudioMass is an open source audio editor that runs entirely in the browser: trim, fade, normalize, apply effects and export, all on a proper waveform view. Your audio never leaves your device, which makes it a rare thing among online editors.
Best for: Use this when you need to trim or clean up an audio clip privately without installing an editor.
Pros
- Fully client-side, audio files are never uploaded
- Real editing features: effects, fades, normalization
- Open source and genuinely free
Cons
- Single track editing, it is not a multitrack DAW
- Very large files can strain the browser tab
