hi all,
i need to write an application that listens for DTMF tones from standard audio input (from the mic) and executes an action depending on the digit extracted from the DTMF tone. Unfortunately i have short time to set up this application and i'm really new to this kind of problem
(sound analisys). I take a look at JTAPI but i don't have any telephone in this context, i just have to analyze a normal sound signal from the sound card. I found some applications on the net but most of them need a modem and don't manage the input from the sound card, the other are win apps and i cannot configure the actions.
I'm a java programmer so it would be nice if there's a library that i can use and accept an audio stream in input and give the digit in output... if something like that doesn't exist i need at least a java implementation of a DTMF decoder.
thank you for your help.
