What is Voice Recorder?

Voice Recorder captures audio directly from your microphone. One tap to start. All recording happens on your device — nothing is uploaded or stored remotely. Use it for voice memos, meeting notes, or anything you need to save.

Audio is captured by the MediaRecorder API directly on your device and written to a Blob in memory. The waveform you see is a live FFT of the mic input — once you stop, the full clip is decoded back into a static waveform so you can scrub before saving. Default output is WebM with Opus at roughly 24-32 kbps mono, plenty for speech.

How to use

1. Step 1 — Click the record button and grant microphone permission when prompted.
2. Step 2 — Speak into your microphone. Watch the live waveform and recording timer.
3. Step 3 — Stop recording, drag the trim handles to crop silence from the start or end if you want, then pick WebM, MP3, or WAV and download.

When to use

• Capturing a quick voice memo during a brainstorming walk without launching a phone app.
• Recording meeting notes or interview audio when a dedicated recorder isn't around.
• Practising a presentation or language pronunciation and listening back for filler words.

Result

During a brainstorming session, you hit record and capture a 2-minute voice memo about a project idea. Play it back to verify the audio is clear, then download the file to reference later.

FAQ

Where do my recordings go after I stop?

They stay in memory as a Blob and disappear when you close the tab. Nothing is uploaded. Hit the download button before leaving the page if you want to keep the audio — once the tab is gone, the recording is too.

Which download format should I pick — WebM, MP3, or WAV?

WebM with Opus is the native capture format — smallest file, great quality for speech. MP3 is the safest pick when sending the file to an app or device that does not play WebM. WAV is lossless PCM — pick it when you plan to edit the recording in audio software like Audacity or Reaper.

Can I record longer than 30 minutes?

Yes, the recorder has no built-in time limit, but the audio is held entirely in memory. On a phone with little free RAM, multi-hour recordings can crash the tab. For very long captures, stop and download every 15-20 minutes to be safe.

Why is my microphone not working?

Browsers require an explicit permission grant per origin. If you blocked the prompt earlier, open your browser's site settings, set microphone to Allow, and reload. On laptops, also check the operating system mic permission for the browser.

Can I pause and resume the same recording?

Yes. The pause button stops capturing input without finalising the file, and resume picks up where you stopped, in the same WebM. Useful for skipping a phone interruption mid-take without splitting the audio.
