Audio masking is a technique used to create additional privacy in public spaces. Enabling audio masking will add a mask to the audio playing through your speakers that includes pink noise and conversation snippets. This provides additional anonymity to your patrons since it becomes more difficult to overhear other conversations taking place in the room.
Use the volume sliders to increase or decrease the volume of the two masks. Increasing the volume will increase the level of the mask file relative to the streaming audio.
