Split audio at silence into several files and remove all silence

Split audio at silence into several files and remove all silence

Hi,

I want to split an audio file at silence into several files and remove all silence.

I found:

sox input.wav output.wav silence 1 X 0.1% 1 X 0.1% : newfile : restart
Which creates perfect splits. However at the end of each output file there is still silence.


Thanks for the help!

Florian Zand

Hi, In my case, this effect removes the silence from the end as well:
silence 1 1 0.1% 1 1 0.1% reverse silence 1 1 0.1% 1 1 0.1% reverse :
newfile : restart
By the way, how much silence you have at the end of each output file when
using your version of the effect (=without using the reversing trick above)?
regards, Mikko

I've never used the "silence" effect, but a few minutes reading the
manual makes me curious.

- what are the "X"s in your command meant to do?

- did YOU read the manual section about "silence"?  If so, what
   happens when you try the method it describes for trimming silent
   periods from the end of a file?


If you try it, and it doesn't work, come back and ask again... and then
it might help if you also told us what version of sox you're using.
