fiddle of a hardcore fft analysis will detect such frequency peak.

then send a message [ twidge command ( to [shell], this is a SO simple way to send stuff over to twiiter in linux. 

Have fun,

Hi all.

Long time lurker.  Infrequent poster........

I'd like to setup a very raw alarm type of system where I have a mic listening for a certain frequency.

Once that frequency is detected, pd will do something (maybe send out a text-message or something.....via twitter?)

I have a vague idea about how to approach this but just in case someone has done something similar I'd rather not reinvent the wheel.

Thanks for any input.
