Abstract

There has been much research in the past few years on loudness perception and metering. Recently, the authors developed an objective loudness algorithm that accurately measures the perceived loudness of mono, stereo, and multichannel audio sequences. The algorithm provides a single loudness reading for the overall audio sequence. In broadcast, film, and music applications it is desirable to have a real-time loudness meter that can track the loudness of the audio signal over time. The new meter would be used in conjunction with existing metering methods to provide additional information about the audio signal. In the present study, the requirements for such a meter are examined and new subjective testing methods are devised to help in the development and evaluation of a new meter.
