Voice Recorder
This lesson is part of Web Developer Tools · All levels
Summary
The voice recorder records the sound from the microphone and stores it as an audio file on the device. Modern browsers use the MediaRecorder API to capture audio, then generate formats such as WebM or Ogg depending on browser support. This tool is suitable for voice recordings, short interviews, or presentation exercises. Check the sound level and room before recording for clean results.
Key points
- MediaRecorder captures audio streams from the microphone into files
- The resulting format depends on browser support, generally WebM or Ogg
- Local recordings don't need to be uploaded to the server
- Use a quiet room and a stable microphone for best results
- Save the master recording before editing or compressing it
