SYSTEM AND METHOD FOR OPTIMIZING LOUDNESS AND DYNAMIC RANGE ACROSS DIFFERENT PLAYBACK DEVICES |
摘要 |
Embodiments are directed to a method and system for receiving, in a bitstream, metadata associated with the audio data, and analyzing the metadata to determine whether a loudness parameter for a first group of audio playback devices are available in the bitstream. Responsive to determining that the parameters are present for the first group, the system uses the parameters and audio data to render audio. Responsive to determining that the loudness parameters are not present for the first group, the system analyzes one or more characteristics of the first group, and determines the parameter based on the one or more characteristics. |
