Hello DSPC Team,
I want to smooth the FFT results along the time axis.
Specifically, I want to calculate a moving average across n adjacent frames for each frequency bin.
Is there any existing dsp concept module that can do this efficiently?
```
For example:
bins-1: b[0], b[1], ..., b[n]
bins-2: B[0], B[1], ..., B[n]
...
bins-m: m[0], m[1], ..., m[n]
result: (b[0] + B[0] + ... + m[0]) / m,
(b[1] + B[1] + ... + m[1]) / m,
...,
(b[n] + B[n] + ... + m[n]) / m
```
Thanks,
