Audio effects in ffmpeg [closed]

Question

Does ffmpeg audio effects like reverb? Can I work with the channels (to detain them, mix)? If so please link to code samples or examples of codes. thanks in advance!

Answer 1

You can use "RUBBERBAND" for changing pitch and tempo of audio,

If you want to change/add effect of audio from video file then use following code with 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 generate a new video file with pitch change in audio

Answer 2

You're looking for SoX, which is like ffmpeg for audio.
