Your browser will ask for permission to use the microphone. Recording starts once you allow it.
Record straight in the browser. Watch the input level as you go, pause and resume, then play the take back and save it as WAV or MP3. No app, no account.
Recording needs microphone permission, which your browser will ask for. The audio itself stays inside this page and is never uploaded.
Questions
Is the recording uploaded anywhere?
No. Sound from the microphone stays inside the browser, and the only way it leaves is the download you start yourself. The decoding and encoding done for the export also happen on this page rather than on a server. Recording does require microphone permission, and it is the browser that asks for it — all this tool can do is receive audio from a microphone you have already allowed.
Should I save WAV or MP3?
WAV to hand to an editor or a transcription service, MP3 for sharing and storage. WAV is uncompressed — it discards nothing, and costs roughly 16 MB a minute in stereo (this tool writes 24-bit; a 16-bit file would be two thirds of that). MP3 at 192 kbps is about 1.4 MB a minute, and 320 kbps about 2.4 MB. For spoken material 192 kbps is plenty; going higher buys very little you can hear. If you are unsure, keep the WAV — you can always make it smaller later.
My recording disappeared after I stopped
The take exists only inside the page, so a reload, a closed tab or a restart all lose it. There is no autosave: leaving recordings of someone’s voice lying around on their device without being asked is not a good default for a tool like this. Nothing is kept until you press Download, so save as soon as you have checked the take, and save in sections during a long session.
Can it remove noise or raise the volume?
This tool records and nothing more. Level and tone belong to the mastering tool, separating vocals from backing to the stem separator, loudness measurement to the key & BPM analyser, key and tempo to the key & tempo changer, and format conversion to the file converter. The intended path is to record here, save as WAV, and take that file to whichever page does the next job.
Does it work on a phone?
Yes, with two caveats. Another app holding the microphone — a call, a voice memo — stops a take from starting. And switching the screen off or moving the browser to the background can end a recording, because the operating system decides to. For a long take on a phone, keep the screen on and this page in front. If you are using a headset microphone, connect it before opening the page.
