Hello there.. I am working on a project that requires DTMF decoding through software on an IBMPC. I am using a SB card to sample the tones through a microphone and I could sample anywhere from 300-13000hz. My question is what methods are there to decode the sample? Are there any algorythms allready out there that I could learn from? Even knowledge on basic frequency detection would be most helpful. Thanks!
