Audio artifacts from CMSIS/DSP Q15 => float => Q15 conversion

I use CMSIS/DSP library in an audio application. I have issues with the conversions 16 bits PCM (=>) Q15 => float => Q15 (=>) 16 bits PCM (in fact no real conversion between 16 bits PCM and Q15, as I...

STM32F427ZG and CMSIS FIR Filters

I am using STM32F427ZG and have a query about the CMSIS FIR Filter functions. We require highest possible speed in a 16 bit environment. I have been comparing speeds for the q15,q31 and float32 FIR...
