TAudioConverter can convert audio formats in bulk, so if you want to convert a big batch of sounds or songs and don't want to go through them one by one, this tool will make the job much easier. You can convert up to eight tracks at a time.
Most currently popular formats are supported by the application, so you won't have problems when you go to play your new songs on any music player. Some of the formats include MP3, M4A, FLAC, and WAV.
Lastly, it's worth pointing out that in addition to extracting the audio from any video you want, you can also easily extract the tracks from any CD.
