Developer: Anand
Genres: Photo & Video, Utilities

Super simple to use. Just 3 steps:
          1. Drag & Drop any number of video or audio files.
          2. Select whether the audio needs to be extracted as is or converted to .mp3.
          3. Click Extract Audio. That's all!

Two modes : As it is. / As .mp3
          As it is : The audio tracks are extracted while maintaining the codec(aac/ac3/etc.,) & number of channels (5.1/7.1/etc.,) as it is and kept in a relevant container without any encoding.
          As mp3 : The audio tracks are encoded to mp3. (if multi-channel audio tracks are present in the input, they will be converted to stereo since mp3 don’t support multi-channel audio).
