AudioMass is a browser-based audio and waveform editor that processes files locally without a backend service. It can record audio or open existing tracks, and provides cut, copy, paste, trim and effect-processing tools for editing complete files or selected regions.
Its multitrack mode arranges audio as movable clips across multiple channels, with volume, pan, mute, solo, record-arm and mixdown controls. Sessions can be saved in AudioMass’s own compressed project format and reopened later.
This is free and open source software.
