Hi, yohannes No, it's not absurd. Tell us a little bit more about your application. I am out of the project game for now, but have some long term goals for solving this sort of problem.
For example, you send a sound out your speakers. You want to recieve a new sound from the room on microphone that is not the sound coming from the speakers. This becomes a system identification problem. You need to find the delay between the speakers and microphone and the transfer function (a filter) between speakers and mic. Then, you digitally apply the filter and delay to your signals as they would be played and subtract that copy from the signal received by the mic.
