How does this tool work?

Records audio signals from your microphone directly in the browser with professional level metering and multi-format export.

Select your microphone and begin recording. The live visualizer displays frequency spectrum and input levels in dBFS. Pause and resume your session at any time. When stopped, review the recording on the waveform player and export as uncompressed WAV, MP3, or WebM.
