Hello! What I need to do is to get a full spectrum of a whole sound I created (with _system.createSound()_ function).  
   
I tried to adapt code from the answer given [here][1], but I couldn’t find any Unity’s alternative for **FMOD\_DSP\_FFT\_SPECTRUMDATA** , but also Unity’s **getParameterData()** function has completely different set of parameters to pass into (index, data and length).   
  
  
Here’s a snippet of code I have by now (the last line is commented out, because it obviously is wrong):

```
FMOD.DSP_PARAMETER_FFT fft;
FMOD.DSP fftdsp;
result = system.createDSPByType (DSP_TYPE.FFT, out fftdsp);
result = channel.addDSP (0, fftdsp);
//result = fftdsp.getParameterData (0, out data, out length);

```

Am I missing something? Thanks in advance.  
  
 P.S. Sorry for posting so many questions lately, just don’t really have time or any advanced knowledge whatsoever to figure this all out by myself.
