Abstract
Improving loudness consistency of an audio stream may include delaying an encoded audio stream and adjusting the delayed encoded audio stream based at least in part on the loudness of the audio stream before a transition and the loudness of the audio stream after the transition. Improving loudness consistency of an audio stream may further include determining the loudness of the audio stream before the transition, detecting the transition, storing the loudness of the audio stream before the transition, and determining the loudness of the audio stream after the transition.
