Patent ID: 7742926

Claim:
A computer-implemented method comprising: obtaining at the computer a block of residual data generated from applying a prediction filter to a block or a subblock of audio signal data; partitioning, by the computer, the block of residual data into a subblock of residual data, the subblock of residual data being smaller than said block of residual data; determining, by the computer, a distribution substantially representative of the subblock of residual data, wherein determining a distribution comprises determining a plurality of statistical measures, including at least two of: a mean of the subblock of residual data, a variance of the subblock of residual data, an estimate of the variance, a skewness of the distribution, and a kurtosis of the distribution; and transmitting, from the computer, in substance the unit of audio signal data to a recipient, utilizing the determined distribution to assist in reducing an amount of data having to be transmitted.
