IIR Filter with 16-bit inputs/outputs and 32-bit coefficients

Question asked by goldscott on Jun 28, 2012

Has anyone modified/created an IIR filter function that takes 16-bit inputs and 32-bit coefficients with 32-bit delay buffer, and outputs 16-bit results?

 

If not, what would be the best way to go about creating this? Modify the iirdf1_fr32.asm library function?

 

Thanks,
Scott
