Frequency segmentation to obtain bands for efficient coding of digital media

Abstract From the Canadian patent

A method is provided for an audio processing device to decode a bitstream representing an , audio signal, the method comprising: decoding an encoded baseband from the bitstream; and , decoding an encoded extended band from the bitstream the decoding comprising: , receiving , data comprising a minimum ratio sub-band size and an altered configuration of sizes of a , plurality of variable size sub-bands determining a smallest sub-band size in the altered , configuration by dividing the smallest sub-band size in a default configuration by the , minimum ratio sub-band size and determining an actual sub-band multiplier by adding an , expected sub-band multiplier to a coded difference value.
