The philosophy

01

Built by audio people

These tools came from real frustrations — normalising a hundred SFX files before a deadline, checking loudness targets before a delivery, hunting for that click in a recording. We built what we needed.

02

Your files stay yours

Every tool runs entirely in your browser. Nothing is uploaded to any server. Your audio never leaves your machine — not even temporarily. We don't have a server to send it to.

03

No friction

No account, no subscription, no trial period, no export limit. Open a tool, do the work, close the tab. That's it. The tools should get out of your way.

04

We're building a desktop app for heavier workflows — batch processing entire libraries, full format support, offline use. The web tools will always be free.
