    Splitting and re-merging audio tracks can be tricky even on a desktop machine - every different video container format has different complications (and sometimes patents, making open-source solutions more difficult). You may have more luck if you focus your question on a single format. – ProjectJourneyman Sep 08 '12 at 04:45

This is not the exact solution but you can try it:

  1. When you play the video file set its volume to zero.

  2. At the same time use the service in which you can play any audio you want.

  3. As service runs at background it has no effect on your video streaming.

  4. When your video end,end your service.

And remember to set volume of your audio file.

  2. After successfully integrate this library first of all extract audio file in WAV audio format. You can use ffmpeg library for do this.

  3. Than using the soundtouch library you can change the audio file pitch and tempo rate and export new audio file in WAV format.
