How to record audio in your browser
- Click record and allow the microphone permission when the browser asks for it.
- Watch the live waveform to confirm the input level is healthy before the take that matters.
- Stop when you are done and listen to the playback to check the recording.
- Export the take as a WAV file — it is generated on your device and saved straight to your downloads.
Frequently Asked Questions
Does recording require an internet connection?
No. Recording happens entirely in your browser; you just need to grant microphone permission.
What format is exported?
Standard WAV (PCM) audio, with selectable sample rates of 16000 / 44100 / 48000 Hz.
Is the recording sent to a server?
No. Recordings are stored locally and disappear when the page closes.
Is playback supported?
Yes. Every recording can be played back directly and downloaded as a WAV file.
What format is the recording exported in?
Uncompressed WAV. It keeps the full fidelity the browser captured; if you need a smaller file, convert the WAV with the audio converter afterwards.
Are my recordings uploaded anywhere?
No. Capture, waveform drawing and export all happen locally in your browser — the audio never leaves your device.
Why does the browser ask for microphone permission?
Recording requires access to your microphone. The permission is granted per site, and the audio stream is used only while you are actively recording.
