Audiomass adds multitrack editing to its browser-based open-source audio suite

Audiomass, a free and open-source audio editor that runs entirely in the browser, has expanded beyond single-track waveform editing to support multitrack sessions. The tool requires no installation or account and handles editing locally in the client, sidestepping the upload-and-process model common to web-based media tools.

The project sits in a niche long dominated by desktop software like Audacity, and its move into multitrack territory pushes it closer to feature parity with traditional DAWs for basic mixing and arrangement work. For developers and hobbyists, it is a useful demonstration of what modern Web Audio APIs and JavaScript can sustain without server-side processing.
