Abstract
Speed constancy or freedom from speed fluctuation ("wows") is becoming more important due to the widespread use of records in radio broadcasting. Equipment of a simplified nature which will evaluate the wow content as a single figure is needed for standardization purposes. Some of the existing equipment is reviewed, and the importance of having a meter with proper ballistic constants for measuring the wow content is shown.
