SBR BIT STREAM PARAMETER DOWN-MIX

Japanese Patent JP2013210674

A

To efficiently decode M audio channels from a bit stream including more N audio channels.

A first source set includes a set of first energy related values associated with frequency bands of first frequency band division. A second source set includes a set of second energy related values associated with frequency bands of second frequency band division. A target set includes a target energy related value associated with a fundamental frequency band. A method includes the steps of: fragmenting the first and second frequency band division into joint grids including the fundamental frequency band; allocating a first value of the set of the first energy related values to the fundamental frequency band; allocating a second value of the set of the second energy related values to the fundamental frequency band; and compounding the first and second values to generate a target energy related value for the fundamental frequency band.
