Audio extraction creates a sound-only file. Choose MP3 for common music players, or a lossless format when your next editing step calls for one.
Three Steps to Your Output
Load the Video
Select Add Media and choose the source video. If it contains several audio tracks, review which track you want to export.
Choose Audio Output
Open the Audio presets and select the required output format. Review the sample rate, bitrate or quality when the preset exposes those options.
Save the Audio
Choose the destination using Save to, then select Convert. Listen to the result and check that the intended track and full duration are present.

Lossless Output Cannot Restore Lost Detail
Saving compressed source audio as WAV or FLAC avoids another lossy encoding step, but it cannot recreate information already removed from the source.
