https://community.intel.com/t5/Intel-Integrated-Performance/how-to-create-a-variable-bandwidth-IIR-filter/m-p/989999#M22183 Dear all,<BR /><BR />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.<BR /><BR />I can only see one method at the moment:<BR /><BR />call ippsAlloc to create a State Structure<BR />for each sample<BR /> generate the values of the taps<BR /> call ippsAlloc to re-populate the State Structure<BR /> call ippsIIROne to filter the sample<BR />next sample<BR />call ippsFree<BR /><BR />I cannot believe this is the most efficient method.<BR />Can anyone help?<BR /><BR />Martin.
