DVD Audio Extractor
Full user review
"Simple & Fast! Just what I needed."
User Interface is easy & simple, guided by a step by step wizard.
It lets you select which audio channel and chapters to use.
Supports MP3, OGG and various audio formats.
None that I experienced.
I only needed it to get the audio from a workout video, and it did it in 3 minutes for a 16 minute video. Thanks.
