You need to record a quick idea, a voice note to transcribe later, or the audio from a test call, and you don't want to install a recording app just for that. The browser already has microphone access through the MediaRecorder API — no extra software needed to record audio and save it as a file.
How a browser-based recorder works
The browser asks for microphone permission (the same prompt you already know from video calls), and from there it records the live audio stream, encoding it directly as WebM with the Opus codec — an efficient compressed format, no post-processing needed. When you finish, the browser generates a downloadable file with the recorded content, without that audio ever passing through an external server.
Pausing and resuming without losing the recording
Unlike simply stopping and recording again (which would create two separate files), pausing and resuming keeps everything within the same continuous recording. This is useful for long voice notes where you get interrupted midway, or for recordings where you need a moment to think before continuing without splitting the file into pieces.
The audio level indicator
While recording, a visual indicator shows the captured volume in real time (calculated from the signal's RMS energy). It's useful for checking at a glance that the microphone is actually picking something up at a reasonable level — neither so low that barely anything registers, nor so high that it saturates.
Frequently asked questions
What format is the recording downloaded in? WebM with the Opus codec, a compressed audio format with good quality and small size, widely supported.
Is my recording uploaded to a server? No. The whole process — capture, encoding and temporary storage — happens in your browser; the file only exists on your device.
Do I need special permissions? Just the standard microphone-access permission any browser asks for, the same one you'd use for a video call.
Can I record long sessions? Yes, there's no duration limit imposed by the tool; the real limit is your device's available memory.
Record with your microphone directly from the browser using the audio recorder: pause, resume and download instantly, with nothing to install.
