  My Activity code is as follows :

• Can FFMPEG or any other project detect an audio file contains only noises ?

  2 octobre 2014, par coral chen

  I have a batch of audio files which recording people’s voice. But some of this audio files record only noises or microphone burst. I want to detect these files and jump over them while processing my program.

  I’m not sure whether ffmpeg can do this. If yes, could you guys provide me a link of that method ? If not, do you know if there is some other software can do this ? Or do you have any solution or suggestion to this problem ?

  Thank you.
