Abstract
A method for processing audio data includes determining a first common scalefactor value for representing quantized audio data in a frame. A second common scalefactor value is determined for representing the quantized audio data in the frame. A line equation common scalefactor value is determined from the first and second common scalefactor values.
Claims24
An audio encoder circuit, comprising:
- a scaler/quantizer unit to determine a first common scalefactor value for representing quantized audio data in a frame, a second common scalefactor value for representing the quantized audio data in the frame, and a line equation common scalefactor value;
- and
- a noiseless coding unit to receive the line equation common scalefactor.
A method for processing audio data, comprising:
- determining a first common scalefactor value for representing quantized audio data in a frame;
- determining a second common scalefactor value for representing the quantized audio data in the frame, wherein at least one of the determinings is performed by a processor;
- identifying a line equation common scalefactor value and designating the line equation common scalefactor value as a common scalefactor value for representing the quantized audio data in the frame, wherein at least one of the determinings and identifying is performed by a processor.
A method for processing audio data, comprising:
- determining a first common scalefactor value for representing quantized audio data in a first frame and determining a second common scalefactor value for representing quantized audio data in a second frame;
- and
- quantizing modified discrete cosine transform (MDCT) coefficients with a common scalefactor value having a value of the first common scalefactor value determined for the first frame, wherein at least one of the determining and quantizing is performed by a processor.
