More about the MP4 to MP3 Converter
A concert recording, a DJ set, a music video downloaded as MP4, in all of these the video is basically incidental, the actual thing worth keeping is the audio, and converting straight to MP3 skips carrying picture data along for content that was only ever really about the sound in the first place. This tool extracts an MP4 video's audio track and saves it as MP3, built for casual listening of musical content pulled from video rather than a lossless source meant for further editing. Useful for pulling the soundtrack out of a downloaded music video to listen to on its own, converting a concert or DJ set recording's audio into a portable MP3, or extracting a video's music without keeping the picture when only the sound was ever the point.
