AudioMass
AudioMass is an open-source audio and waveform editor that runs in a web browser.
What AudioMass is
AudioMass is an open-source audio and waveform editor that runs in a web browser. It supports recording and editing audio, including cutting, copying, pasting, trimming, silencing, reversing, and inverting selected regions. Effects include gain, fades, compression, normalization, reverb, delay, distortion, pitch shifting, pitch and speed profiles, and repair tools. A loop editor offers crossfade preview, silence trimming, zero-crossing adjustment, repetition, and the option to open a loop in another editor tab. Multitrack mode lets users arrange clips across tracks, record, use track controls, and mix down; overlapping clips can receive automatic crossfades. Sessions can be saved and reopened as .amss files, and finished mixes exported as WAV or MP3. AudioMass works locally in the browser without a backend and can continue offline after loading. It is free, with a free plan, and MIT licensed; bundled libraries have separate licenses, including an LGPL license for the MP3 encoder. The maker says mobile use is not particularly well optimized, and very large files can consume resources while decoding.

Who it suits
AudioMass suits people looking for a free browser-based editor with waveform, loop, and multitrack tools. It may be less suitable for mobile use or work with very large files.
Verdict
AudioMass combines waveform editing, effects, looping, and multitrack work in a browser editor that can keep working offline after loading. Consider its stated mobile and large-file limitations before choosing it.
