Harker Research: Nielsen's Enhanced Encoding Not 'Format Neutral'
April 27, 2016 at 3:26 AM (PT)
In the latest post on its Radio InSights blog, HARKER RESEARCH CEO RICHARD HARKER finds a major fly in the ointment of NIELSEN's enhanced encoding improvements -- it can be audible on-air.
"What good is it that the meter picks up more listening if encoding drives listeners away?" he wrote. "NIELSEN’s ARUN RAMASWAMY claimed that VOLTAIR introduced audible artifacts that, 'could possibly effect the user experience for our panelists.' Any misused audio processor including VOLTAIR can create artifacts, but the solution is to properly adjust the processing.
"A station using VOLTAIR can lower the processing so that no artifacts are audible," he noted. "That’s not true with the enhanced encoder. NIELSEN’s is a 'one size fits all' solution. If enhanced encoding creates audible artifacts on your station, there is nothing you can do. So it turns out that PPM is still not format neutral. PPM still picks winners and losers based on format encodability."
