25-Seven Systems’ new processor Voltair works to improve PPM’s ability to capture most if not all of a station’s actual listening.
According to Telos Alliance, its new product was prompted by reaction to a Blesser white paper in 2009 that questioned certain aspects of PPM.
According to Blesser, certain kinds of music or voice do not effectively mask the watermark signals, resulting in lower amounts of coding depending on format or voice talent.
“The publication of that paper had the effect of bringing to light a number of people in the radio industry who had questions about the PPM system,” according to Blesser.
