[SoX-users] Detecting and printing timestamps of periods of silence using SoX

[Rahul R. <rah...@gm...>]

Hi,

This mail is in reference to a question I posted on StackOverflow recently.
In short, I want to be able to print the start-stop times of silences in an
audio file, which eventually gets cut into pieces with the silences
discarded. The exact text I posted was the following:

*I am trying to output the begin-timestamps of periods of silence (since
there is background noise, by silence I mean a threshold) in a given audio
file. Eventually, I want to split the audio file into smaller audio files,
given these timestamps. It is important that no part of the original file
be discarded.*

*I tried *

*sox in.wav out.wav silence 1 0.5 1% 1 2.0 1% : newfile : restart*

*(courtesy http://digitalcardboard.com/blog/2009/08/25/the-sox-of-silence/)*

*Although, it somewhat did the job, it also trimmed and discarded the
periods of silence, which I do not want happening. *

*Is 'silence' the right option, or is there a simpler way to accomplish
what I need to do?*

*Thanks.*

To this, I got a reply telling me that I can only do this by modifying the
source code. I tried hard for long but could not make out which file(s) I
am supposed to modify. I hope that you can help me.

Thanks,
Rahul Rajaram.
