Hi,

In FMOD 4, I had this lovely function to work with:

```
FMOD_Channel_GetWaveData

```

But I cannot find documentation or functions similar in FMOD 5 Low level api… What should I use to get this data? Do I need to create a custom DSP like we had to do way back in FMOD 3?

Thanks.

Custom DSP is the replacement for GetWaveData.
