Have a Unity project using the Wwise audio input plugin. Plugin is sending audio out from Unity via a single Unity "audiosource.clip"
Is there a way we can change that so that the main unity audio output buss replaces the single Unity audio source slip? That way we can send all unity audio (main left and right stereo output) out to Wwise not just one audio clip inside Unity
Below is current example:

> using UnityEngine;
> using UnityEngine.Events;

> public AK.Wwise.RTPC MicrophoneLevelRTPC;
> public int SampleRate = 48000;
> public int InitialReadDelayInSamples = 4096;
> [UnityEngine.Header("Invoked on exceeding -48dB")]
> public UnityEvent OnMicrophoneAction;
>

So far audio from the audioclip is getting sent to Wwise from Unity. Problem is want to use several clips and atm only allows for one at a time. Another possibkle spoultion is to be able to have multiple audioclips sent out to audio input plugin. Any thoughts are greatly appreciated
