[asterisk-users] Re: Recorded file processing app wanted

[Steve Totaro]

We shall.  Let's use Google shall we?  Oh, here we find that there are
solutions that can be used in conjuntion with Sox to accomplish just
about anything.  Good ole Google, what a friend!

Use Sox to accomplish everything on his list except getting rid of
silece within the sounds file.  Then run a file splitter based on
silence, run Sox again to remove the silence from the resulting files
and then use a file merge program to put the pieced back together again.
Pretty simple script I think.

Take a look here "Audio::FindChunks - breaks audio files into
sound/silence parts."

Many Thanks,
