[android-developers] Re: Help me in detecting sound pulses (basically frequency detection)
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.

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

[android-developers] Re: Help me in detecting sound pulses (basically frequency detection)
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 '.' -- You received this message because you are subscribed to the Google Groups Android Developers group.

Hi all On May 12, 9:22 am, Prady pradp...@gmail.com wrote: 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.
