Enables the audio only to be extracted from a video file, when choosing Wave as the extraction type, the source video can contain any audio type. If mp3 or AAC are chosen then the source video has to contain this audio type as it is copied 1:1 without reencoding.

When choosing the extraction the audio stream number can be chosen, note this stream number is per audio stream so 0 is the first audio stream, 1 2nd, regardless of other streams within the video file.

Extension: .wav, .mp3, .m4a
