Hi,:p
Someone can show me the way to controll I/O in soundcard and the way to create DTMF( dual tone multifrequency) signals ....in C/C++. How to get data from "line In" and "microphone"? and then (sampling, frequency progressing), send it to "line OUT" ? I can create a sound with a single frequency but I can't create a sound with dual frequencies??
