Fast Fourier Transform (DSP) + Audio Analysis

I need a fast fourier transform on an audio analysis of the input from a digital microphone with I2S digital audio protocol. Using a STM32L4, direct memory access has to be used (DMA) and RTOS.

Current code working but doesn't have a FFT and missing also a exponential moving average filter for SLOW measurements (each second), the FAST measurement (125ms) is being read correctly.

It need to be provided the 3 frequencies with highest power on each measurement. Also max, min, avg, Leq. of the Audio measurements

Please only highly experience in DSP embedded systems in C.
