Hello

I’m using Resonance Audio and FMOD 2.02.15 in Unity  
I’m enjoying spatialization but I don’t really like sound muffling so I’ve decided to add EQ.  
The problem is that when using resonance audio source or listener with any EQ, distortion and crackling appear in the sound.  
It doesn’t matter whether I use this chain at an event, mixer, or separate track in an event, the crackling always appears (EQ does not work before the resonance plugins so its always after spatialization).  
The problem occurs both in FMOD Studio and in Unity

UPD: Glitches can be heard even in events that have no effects and are absent in events with effects.

Hi,

Thank you for sharing the information and version number.

I have tried adding a `Multiband EQ` after both the `Resonance Audio Source` and the `Resonance Audio Listener` effect in FMOD Studio, but I’m not hearing any noticeable distortion or crackling on my end.

Would it be possible to share a [profiler recording](https://fmod.com/docs/2.02/studio/profiling.html#recording-a-new-session) or some screenshots of your event?
