Nielsen Reveals Voltair Test Results.

Story by Inside Radio

Nielsen says its new PPM encoders produced “ROUGHLY EQUIVALENT” results when compared with the Voltair audio processor that brought the encoding issue to the industry’s attention in such a dramatic way this year. Nielsen revealed results of comparisons of the two technologies today during a webinar about the new encoders, which begin to roll out on Monday.

The comparison involved seven stations in the Baltimore-Washington, DC market that agreed to unplug their Voltair during a portion of the test week and replace it with Nielsen’s enhanced CBET encoder. Results were compared to the previous three weeks, when the stations had the Voltair plugged into their transmission chain, to arrive at indices that could be compared. Nielsen says both units produced indices that were “ROUGHLY EQUIVALENT".
