AudioMass: browser audio editor. Edit audio and waveforms directly in your web browser.

In simple English

You can cut, record and change audio files right in your web browser. You do not need to install any heavy software on your computer. It handles single tracks and multiple layers of sound at the same time. You can use it to edit podcasts, music clips or voice notes. The code is free to run on your own machine.

What it is

AudioMass is a web-based audio editor built with JavaScript. It gives you a visual waveform view to edit sounds without leaving your browser window.

What it is good for

Solo builders who need to trim a podcast recording, mix a few sound effects or boost audio volume without paying for professional desktop software.
