Extract audio tracks from local audio and video files and export two-channel WAV.

Select a local audio and video file, up to 32 MiB; preview first, then fill in the segments to be processed.

Only process the fragments you fill in. Available formats depend on browser codec support and will not call network transcoding services.

After processing is complete, the results will be displayed here.

  2. Fill in the starting point and length of the interception, up to 60 seconds, and then click "Extract Audio".
