I Have managed to process saved audio file to open, alter and save it back to disc. Now,I wanted to work on a live audio input, Microphone input. There are no such functions in C to capture a live mic input, or at least I couldn't find any.I have seen some help but in other programming languages or OS. Friends on line advised me to use MCI of windows. But i couldn't run a single simple code in MCI functions with out errors. I just want some one show me a simple example to capture a microphone input in C(non other) programming language please. I also wish to get reading material, specifically on my problem.
