You are looking for a SoX that is similar to ffmpeg for audio.

You can use RUBBERBAND to change the pitch and tempo of the sound,

If you want to change / add the effect of the audio from the video file, use the following code with a combination of ffmpeg and rubberband

ffmpeg -i w.mpg -vcodec copy -an tmpVideo.mpg
ffmpeg -i w.mpg tmpAudio.wav
rubberband -p 6 tmpAudio.wav tmpAudioRB.wav
ffmpeg -i tmpVideo.mpg -i tmpAudioRB.wav -vcodec copy finalVideow_6.mpg

This will create a new video file with a pitch change in the audio.
