Method and apparatus for reproducing audio standard media with and without LOUDNESS metadata embedded in New Media Devices

摘要

It provides a Decoder Device for decoding a Bitstream thus produced from an Output Signal of the audio bit Stream Data and audio LOUDNESS metadata optionally containing a Sonority value ReferenceThe device comprises: a Decoder Device Audio Decoder configured to rebuild an audio signal from the audio data; and a Signal Processor configured to produce the Audio Output Signal based on the audio signal, where the proc Esador signals comprises a device for Controlling the gain,Configured to adjust a level of the audio signal; wherein the control device comprises a sound profit Decoder configured to create a reference value of LoudnessWhere the value of the value of the sound LOUDNESS is the reference in the case that the value of the Sonority of reference (4) is present in the stream of bits; wherein the control device comprises a Gain Calculator configured to calculate the gain A Gain value based on the value of the Sound and based on a value for theVolume control, which is provided by an external user interface that allows a user to control the value of Volume control, where the gain control device comprises a Processor configured to control the LOUDNESS of the sound Signal output Audio based on the value of the gain.
