Hi Folks, There’s been a few informative posts regarding buffer settings using System::setDSPBufferSize, and I’m wondering if that method has been usurped by the DSP Buffer Settings available via Unity \> FMOD \> FMOD Settings.

In my particular case, I have added a few musical instruments to an iOS app and the latency using the default 512 buffer length is really high.

Thanks, Matt

Hi Matt,

The setting is just calling `setDSPBufferSize`, you can check this in the `RuntimeManager.cs on line 326 - 330`. Changing the buffer length in the settings may help the issue.

Hope this helps!
