Split audio file but only in pauses


I've been playting around with sox and using the trim command it should be fairly simple to split the whole audio into n parts (with a fixed length per part).

However as I intend to split spoken recordings it might happen that a simple splitting will split in the middle of a word.

Is there a way to prevent that and make sure that parts contain "whole words"?


Solution

  • Take a look at the sox silence command on the (archived) sox webpage for manual and Sound eXchange on sourceforge.

    sox original.wav new.wav silence 1 0.5 2% 1 2.0 2% : newfile : restart
    

    Parameters:

    original.wav - the audio file to be spliced.

    new.wav - will be the name of the new audio files with numbers appended to each slice (new1.wav, new2.wav, new3.wav...).

    silence - name of the effect.

    1 0.5 2% - above_periods, duration, threshold.

    1 2.0 2% - below_periods, duration, threshold.
