- Abstract
- The subjective effect of flutter on audio program is reviewed, leading to the concept of “flutter index.” This information is analyzed to show the validity of using a single number, flutter index, as a measure of the relative quality degradation imparted to audio recordings by the flutter in the measured equipment. A proposed IRE Standard on Flutter Index Measurement, based on the above information, is then discussed.
