[#23] FFT Spectrum Analysis - Audio DSP On STM32 (24 Bit / 48 kHz)

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:    • [#5] IIR Filters - Audio DSP On STM32 with...   More detailed explanation on the block-based processing approach with the help of the CMSIS DSP library you can watch here:    • [#15] CMSIS DSP Library - Audio DSP On STM...   Download the code here: https://github.com/YetAnotherElectron...
