I’d like to get the value of freq at the point of n seconds, after getting sounds from SoundIn.ar and doing FFT -> IFFT. (It may be wrong?)

Is there a better way to do it?

Tried to just plot:

```
(
{ var in, chain;
in = SoundIn.ar(0);
chain = FFT(b, in);
IFFT(chain);
}.plot(5.0);
)
// For example, how to know the frequency that is sounding the most at 2 seconds?
```

Thanks!
