Abstract

Recently, much effort has been devoted to developing and evaluating an algorithm that can accurately measure the long-term loudness of mono, stereo, and multichannel audio signals. This has resulted in a new ITU Recommendation that provides a single loudness reading for the overall audio sequence. In many applications it is desirable to also have a measure that can continuously track the short-term loudness of the audio signal over time. Such a meter would be used in conjunction with existing metering methods to provide additional information about the audio signal. In the present study, subjective test methods are devised to aid in the development of a short-term loudness meter. Subjective methods for evaluating the meter’s performance are also explored.
