Why this exists

The purpose

Someone needs the first thirty seconds of a song for a video. A teacher wants a backing track a tone lower so a class can sing along. A researcher has an interview with a fan humming through it. A musician wants to slow a passage down to learn it, or lay a guitar part over a beat.

These are ordinary, useful jobs. None of them should need an install, an account, a watermark or a queue. That is what this is for: practical audio editing, done properly, for people who are not audio engineers.

What you can do here

• Edit a track: cut, change speed or pitch, volume, fades, and reverse.
• Clean up a recording: repair clicks and clipping, remove background noise and hum, and normalize the level.
• Combine files: join them end to end, or mix them in layers and record your own tracks.

The three commitments

Your audio stays yours

Every tool runs in your browser. Your file is never uploaded, so there is no copy of it on anyone else’s computer. This isn’t a policy that could change next quarter: there is no server that could receive your audio even if we wanted it.

Nothing is dressed up as something it is not

The repair tools are signal processing, and the site says so rather than calling them AI. When a tool reports a result, that number was measured, not invented.

Free, without a catch

No account, no email wall, no trial that expires, no watermark. The whole site is static pages and some JavaScript, so it costs almost nothing to run.

What it is not

It isn’t a full digital audio workstation: there are no MIDI, plugins or automation lanes, and it won’t separate a finished song into vocals and instruments. If you need that, use a workstation. Audacity is free and excellent.
