Hi All,


I have been working on a project where I need to record a call in Asterisk and then split the recording into multiple audio files based on a presence of particular sound (i.e. beep) in a recording.
I know this is out of scope for Asterisk but I wanted to benefit from someone else's experience if it has been done earlier.
I have googled a bit and seems that Audio fingerprint(http://en.wikipedia.org/wiki/Acoustic_fingerprint) is something I should concentrate on.
Your views are highly appreciated.


Thanks,
--Satish

You would probably have better results from using a specific frequency tone (or dual tones) as the beep and then using a tone detection algorithm to locate it, in the same way that DTMF works.
