This is similar to using the <a href="https://docs.unity3d.com/ScriptReference/Audio.AudioMixer.SetFloat.html">UnityAPI AudioMixer.SetFloat()</a>, which requires adding an effect and exposing parameters in the AudioMixer. The only difference is that the effect referred to can only be applied to the 'Effect' track of BroAudioMixer, which can be set via <a href="../../../tools/audio-effect-editor">AudioEffectEditor</a>.</td></tr></tbody></table>
