Load your video, choose MP3, AAC or WAV as the output format, and press Extract. The audio-only file downloads once processing completes.
MP3 for wide compatibility, AAC for smaller high-quality files (used by MP4/M4A), or uncompressed WAV if you need the audio for further editing.

The audio stream is pulled out largely as-is, so quality closely matches the source; converting to MP3 applies standard lossy compression at a solid default bitrate.
