Voice Recorder

What this tool does

Voice Recorder captures audio from your built-in or USB microphone directly in the browser. Choose the input, format and quality, switch echo cancellation, noise suppression and automatic gain on or off, watch the input level, pause and resume, and keep several named takes to download individually, as WAV or as a ZIP.

Sometimes you just need to record something now: a voice note for a colleague, a practice run of a presentation, a quick podcast intro or an audition clip. Installing an app or finding the recorder buried in your operating system takes longer than the recording itself.

This recorder uses the browser’s getUserMedia API to open the microphone and MediaRecorder to encode the sound as it is captured, typically Opus in WebM on Chrome, Edge and Firefox and AAC in M4A on Safari. A Web Audio analyser drives the live level meter so you can see clipping before it ruins a take. Recordings are held in the page’s memory, never uploaded, and can be converted to uncompressed 16-bit WAV for editing.

How to use Voice Recorder

1. Choose your Microphone, Format and Quality in the settings panel.
2. Decide whether to keep Echo cancellation, Noise suppression and Automatic gain control switched on.
3. Click Start recording and allow microphone access when the browser asks.
4. Speak and watch the level meter; aim for the green and amber range and keep out of the red.
5. Use Pause and Resume as needed, then click Stop.
6. Play the take, rename it, and click Download or Download WAV; record more takes and use Download all (ZIP) for several.

Tips for better results

• Keep the microphone a hand’s width (about 15 to 20 cm) from your mouth and slightly to one side to avoid popping sounds.
• Turn off the three processing filters when recording music: they are tuned for speech and can make instruments pump or sound thin.
• 96 kbps Opus is plenty for speech; a minute takes about 0.7 MB.
• Set Stop automatically after to cap long recordings such as lectures so they do not run all night.

Common use cases

• Recording voice memos, reminders and messages to send to someone.
• Rehearsing a talk or interview answer and listening back.
• Capturing voice-over takes for a video or slideshow.
• Recording pronunciation practice when learning a language.

Common mistakes to avoid

• Closing or reloading the tab before downloading: takes live only in that tab’s memory.
• Recording too hot: when the meter hits red the peaks are clipped and cannot be repaired afterwards.
• Blocking the permission prompt by accident; you then have to allow the microphone in the browser’s site settings.
