Press record. Nothing is installed, nothing is uploaded — the recording stays on this device until you download it.
Your browser can record audio on its own, so there is no reason for us to see it. The microphone goes straight into the page, the file is built in the tab, and the download link points at your own device. We could not read the recording if we wanted to — there is nothing to read.
It works, with one caveat that has nothing to do with us: a laptop microphone is built for speech and rolls off the low end, so a guitar or a bass sounds thin through it. Anything plugged in over USB is a different world. If the room was noisy or echoey, CleanGrab cleans the recording up afterwards, and if you recorded over a backing track and want the parts separated, that's what the stem splitter on the home page does.
Chrome, Edge and Firefox record WebM; Safari records MP4/AAC, which downloads as an M4A. Both play everywhere that matters and both are smaller than an MP3 at the same quality. The Download as MP3 button is there because plenty of older software still wants one — that is the only path where the audio touches our server, and it is deleted as soon as the file is sent back.
Yes — no account, no e-mail, no time limit and no watermark.
No. It is made and kept in your browser; the download comes off your own device. The only exception is the Download as MP3 button, which converts on our server and deletes the file straight after.
Yes, in Chrome on Android and Safari on iPhone. Keep the tab in the foreground — a phone stops a background tab from using the microphone.
The browser is on the wrong microphone. Check which input your system has selected, and that no other program (a call, a meeting) has taken exclusive hold of it.
No — this records the microphone, not system sound. Capturing what your computer plays needs a system-level tool.
Yes, with the Download as MP3 button. Browsers themselves cannot write MP3, so that one step happens on our server.
