Utility
Adaptive loudness normalization for audio object clustering
12 Mar 24
A method of processing audio content including a plurality of audio elements comprises: clustering the plurality of audio elements into a plurality of clusters of audio elements; and for a cluster among the plurality of clusters: for each audio element in the cluster, determining a measure of energy that the audio element contributes to the cluster; for at least one audio element in the cluster, determining a compensation gain based at least in part on the measures of energy for the audio elements in the cluster; and applying the compensation gain to the at least one audio element in the cluster.

Utility
Method and apparatus for controlling enhancement of low-bitrate coded audio
12 Mar 24
Described herein is a method of low-bitrate coding of audio data and generating enhancement metadata for controlling audio enhancement of the low-bitrate coded audio data at a decoder side, including the steps of: (a) core encoding original audio data at a low bitrate to obtain encoded audio data; (b) generating enhancement metadata to be used for controlling a type and/or amount of audio enhancement at the decoder side after core decoding the encoded audio data; and (c) outputting the encoded audio data and the enhancement metadata.
