Feedback Reduction Project

[Yacob_UK]

Hi, I am trying to implement a digital feedback reduction system. I have the basic idea in very basic psuedo code floating around in my head, but I am trying to get my head around alot of new areas to realise this project.

I though it might be useful to have an idea of the inner working of some of the current commercial products available on the market.

I appreciate that any coding etc is highly sensitive commercial data, but if anyone has any pointers as to the basis of the systems at a 'code' level that would be awsome

Further areas I am trying to research is 'C/C++' coding for audio. I can't find any solid resources either online or offline as a good starting point...... any suggestions.....

Finaly I am getting my head round Matlab (slowly) and I wondered if any one has any good beginning resources for Matlab coding for Audio applications... Functions I intend to use are: FFT, DFT, Band Stop Filtering (Notch), Variable filter deployment, and some kind of Energy Power comparisons.
