[#15] CMSIS DSP Library - Audio DSP On STM32 (24 Bit / 48 kHz)

In this video I want to show you how to setup and use ARM's CMSIS DSP library for realtime audio processing showing two examples with FIR and IIR filters.
For further details on the STM32 hardware configuration and the DMA usage, please watch my first video on the STM32 audio-dsp sessions where I explained this topic in detail:
