We are able to detect speech..  but we are facing problems with
detection of music(non speech audio) ,If any body has any idea let us
know.
Thanks ,

hey thanks for the linkif you have any other material then please
share it...
a material with some code will be great...

 You need to take a look at an algorithm called Fast Fourier

 You can find one implementation here

 Good luck.

Hi Pradeep
I have transmitted some pulses corresponding to a Morse code pattern.
e.g, if the code is ..---.-.---.-- then '.' will have a particular
frequency pulse and '-' will have a particular frequency pulse. Thus
it is a stream of pulses having two frequency. you can clearly
understand that the stream is formed according to the Morse code
pattern. Now I'm using this app as a Beacon tx. This is my sound
source. Now in another device I wanna receive this pulses and analyze.
That means if I get pulse of freq X then its a '-' and if I get freq Y
then its a '.'

 Hi Soumyajit,

 Can you clarify on a few things on your need, for example: what's the
 input source for the sound pulses that you will be getting, because If
 its a hardware connected to your device then I guess your device would
 need to be interfaced with linux kernel. If the sound pulses are
 stored in a file, and you plan to read them from an android app, then
 you can try digging a it a bit in media framework(using which you can
 split and analyze your sound samples), but I am not sure whether your
 requirement of basic reception and detection of frequency would be
 met.

 Regards,
 Pradeep
