Hi,
I am learning c5535 by running applications in teaching rom5000. My mind is confused in Chapter 11 which is adaptive noise reduction. There are 4 steps in main.c (no processing, filter output left-filter output right, filter output only, error output only). I hear sound in only step2 and i don't hear anything in no process step, error output only and filter output only steps. I read adaptive filter header file and i changed adaptive filter configuration adaptive_filter_asm_1(delayed_input,mono_input) instead of adaptive_filter_asm_1(mono_input,delayed_input). Nothing changes. If i change no processing step:left_output = left_input; right_output = right_input instead of mono_output = left_input; mono_output = right_input, i can hear sound clearly. But i wonder how can i test this filter and how can i hear only error output or only filter output? Sorry for my questions, i am newbie.
Regards Ipek
