Abstract
A novel audio ducking method that is aware of the loudness levels of the audio content is provided. The method specifies a minimum loudness separation between audio tracks that are designated as masters and audio tracks that are designated as slaves. The method attenuates the volume of the slave tracks in order to provide at least the minimum loudness separation between the slave tracks and the master tracks. The amount of attenuation for a slave is determined based on the loudness levels of the slave and of a master.
Claims21
A method comprising:
- receiving a minimum loudness separation requirement between two audio tracks;
- detecting a loudness of a first audio track and a loudness of a second audio track;
- and
- reducing the loudness of the first audio track in order to meet the minimum loudness separation requirement, wherein the reduction is based on the detected loudness for the first and second audio tracks.
A non-transitory computer readable medium storing a program which when executed by a set of processing units reduces the loudness of a first audio track, the program comprising sets of instructions for:
- receiving a minimum loudness separation requirement between two audio tracks;
- detecting a loudness of the first audio track and a loudness of a second audio track;
- and
- reducing the loudness of the first audio track in order to meet the minimum loudness separation requirement, wherein the reduction is based on the detected loudness for the first and second audio tracks.
An audio system comprising:
- a set of processing units;
- and
- a non-transitory computer readable medium storing a program which when executed by a set of processing units reduces the loudness of a first audio track, the program comprising sets of instructions for:
- receiving a minimum loudness separation requirement between two audio tracks;
- detecting a loudness of the first audio track and a loudness of a second audio track;
- and
- reducing the loudness of the first audio track in order to meet the minimum loudness separation requirement, wherein the reduction is based on the detected loudness for the first and second audio tracks.
