Extract Audio from Video
Pick the video, pick the format, download just the audio. For m4a the tool tries to copy the original AAC without reprocessing, which is instant and lossless; mp3 and wav involve conversion, because the codec differs.

How it works
The base command is -vn, which discards the video. For m4a we use -c:a copy: the audio comes out identical to what was inside the video, because MP4 and M4A are the same container. When the source codec does not fit the requested format, the tool re-encodes — mp3 and wav always do, since no common video stores audio in those codecs.
- m4a by stream copy when the source is already AAC: lossless and immediate
- mp3 with libmp3lame at high quality, and wav as uncompressed 16-bit PCM
- Also accepts an audio file as input, to convert between formats
