Recording straight from your microphone
This recorder captures your microphone through the browser and writes the audio into the page, not to a server. Use it for voice notes, podcast takes, song ideas or language practice, then trim and export without installing anything.
A live scrolling waveform shows level as you speak, so you can catch a signal that is too hot or too quiet before you have recorded ten minutes of unusable audio. Optional reverb, equalisation and echo are applied to the monitor path so you can hear the treatment while performing.
Recordings can be exported as WAV for editing or MP3 for sharing, and passed straight into the cutter to trim the false starts.
How to use the voice recorder
- 01Allow microphone access when the browser asks.
- 02Check the input level on the live waveform and adjust your distance from the mic.
- 03Record, pause and resume as needed.
- 04Apply effects if you want them, then export as WAV or MP3.
Frequently asked questions
No. The microphone stream is processed and stored in the page only, and is gone when you close the tab unless you export it.
Browsers only allow microphone access on secure origins and after explicit permission. Check the site permissions in the address bar and that no other app has exclusive use of the device.
This tool records microphone input. To sing over a backing track, use the karaoke recorder, which plays the track and captures your voice together.
