Hi there, a friend is looking for a way to do DTMF recognition in Pd. I know there is this Goertzel algorithm <<a href="http://en.wikipedia.org/wiki/Goertzel_algorithm">http://en.wikipedia.org/wiki/Goertzel_algorithm</a>> and I wonder if anyone has already implemented something about it in PD.<div>
<br></div><div>Maybe some other option?<br><div><br></div><div>thanks</div><div>Alex</div></div>
