Method Detail

computeSMRs

double[] computeSMRs(double[] samples,
                     int[][] scF)

Compute the Signal-to-Mask Ratios for the sub-bands of the input PCM audio frame.

Parameters:

in - The input PCM audio frame whose samples are doubles in the range ]-1.0, 1.0[.

scF - The scalefactors for each subband (dimensions [SBLIMIT][3]).

Returns:

An array containing the signal-to-mask ratios for each subband.
