Maztr's free online Microphone Tester & Recorder allows you to test your device's microphone and optionally record an audio file. You can also use the Test like a dictaphone or dictation machine. Pause and resume recording at any time, then play or download the recorded file in WAV format.

To get started, simply click the "Record" button and allow microphone access when requested by your browser. You can record up to 1 minute of audio, as often as you like, while Maztr Pro and MP3 users can record up to 30 minutes of audio. Each minute of recording will create a WAV file approximately 6MB in size.
