Help Needed Regarding Project Graphical Equaliser

Started by singla January 1, 2007
Hi everyone
I m B-tech final year student
i m trying to implement graphical equalizer (real time) with
TMS320C6711 kit. (Final Year Project)
I wanna know that
1)Is there any way to introduce adaptive signal processing to it?
2)also ,is there any standard algo to be followed for the task?

  I will really appreciate any kind of inputs in this regard
  Thank You

What would you adapt? To what stimulus?

Automatic assignment of notch filters for acoustic feedback control is commonly seen on some midrange graphics. None of the adaptive efforts seem to work particularly well, (Flute is kind of difficult to distinguish from feedback!), so most people use them in a set it in advance mode, but something of the sort is an obvious candidate.

Cascaded biquad sections? You can compute the parameters off line for a graphic as you are working to fixed centre frequencies. HTH. Regards, Dan.
