I want to create a variable bandwidth IIR Filter (i.e. the values of the taps is different for each sample)and was wondering how to go about it and still maintain maximum speed.
I can only see one method at the moment:
call ippsAlloc to create a State Structure
for each sample
generate the values of the taps
call ippsAlloc to re-populate the State Structure
call ippsIIROne to filter the sample
I cannot believe this is the most efficient method.
Can anyone help?
