music echo cancellation

Started by Navin March 7, 2002
hello all,
I have implemented a 16 bit fixed point (simulation on a PC) nlms based
algorithm in c. While this seems to work great for audio input that is
vocal, i seem to be running into problems when i use music (guitar and bass)
inputs. are there any issues that i need to consider/ what would the
differences be? i figured music would have a higher eigen spread and so
adjusted the value of the step size accordingly (i think..)
thanks in advance,
