The Wwise Project Adventure

Through the General tab you can set the volume threshold and the maximum voice instances for each platform.

Setting platform volume threshold and voice instances

Volume Threshold:

The volume threshold is the default volume level below which voices are managed by behaviors defined in the Advanced Settings tab of the Property Editor, essentially determining the volume when voices will either be killed or sent to virtual voice.

Max Voice Instances:

This value defines the maximum number of simultaneous voices that can be active at the same time in the entire project. Virtual voices do not count as active voices. Over this limit, voices with the lowest priority will adopt their virtual behavior. If priorities are equal, older sounds will be considered having a higher priority.
