Voltair Watermark Monitoring & Processing


Designed to give you greater confidence that listeners are counted when it matters most--your station's ratings.


Voltair M

Voltair M includes Voltair's great diagnostic features, but doesn't process the original audio. Ideal for facilities that want visibility into their encoding system, but don't need Voltair’s full processing capabilities.


Audio Delays

Program Delay Manager

Program Delay Manager (PDM) brings ease of use, transparent audio quality and program director friendly features to take an old process to an entirely new level.
