Abstract
A device includes a receiver and a decoder. The receiver is configured to receive stereo parameters encoded, by an encoder, based on a plurality of windows having a first length of overlapping portions between the plurality of windows. The decoder is configured to perform an upmix operation using the stereo parameters to generate at least two audio signals. The at least two audio signals are generated based on a second plurality of windows used in the upmix operation. The second plurality of windows has a second length of overlapping portions between the second plurality of windows. The second length is different from the first length.
Claims32
A device comprising:
- a receiver configured to receive stereo parameters encoded, by an encoder, based on a plurality of windows having a first length of overlapping portions between the plurality of windows;
- and
- a decoder configured to perform an upmix operation using the stereo parameters to generate at least two audio signals, the at least two audio signals generated based on a second plurality of windows used in the upmix operation, the second plurality of windows having a second length of overlapping portions between the second plurality of windows, the second length different from the first length.
A method comprising:
- receiving stereo parameters encoded, by an encoder, based on a plurality of windows having a first length of overlapping portions between the plurality of windows;
- and
- generating, based on an upmix operation using the stereo parameters, at least two audio signals, the at least two audio signals generated based on a second plurality of windows used in the upmix operation, the second plurality of windows having a second length of overlapping portions between the second plurality of windows, the second length different from the first length.
An apparatus comprising:
- means for receiving stereo parameters encoded, by an encoder, based on a plurality of windows having a first length of overlapping portions between the plurality of windows;
- and
- means for performing an upmix operation using the stereo parameters to generate at least two audio signals, the at least two audio signals generated based on a second plurality of windows used in the upmix operation, the second plurality of windows having a second length of overlapping portions between the second plurality of windows, the second length different from the first length.
A computer-readable storage device storing instructions that, when executed by a processor, cause the processor to perform operations comprising:
- receiving stereo parameters encoded, by an encoder, based on a plurality of windows having a first length of overlapping portions between the plurality of windows;
- and
- generating, based on an upmix operation using the stereo parameters, at least two audio signals, the at least two audio signals generated based on a second plurality of windows used in the upmix operation, the second plurality of windows having a second length of overlapping portions between the second plurality of windows, the second length different from the first length.
