In this video I want to explain you how to realize audio spectrum analysis based on FFT function on the STM32.
0:01 - General Introduction
7:27 - Code review
12:36 - Testing with tone generator
14:14 - Testing with music
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:
