Abstract (en)
A method measures the masking properties of subband components of a signal and determines a noise level vector for the signal. In the preferred embodiment, a signal is separated to yield a set of subband signal components. Bandpass noise components are also generated. For each combination of bandpass noise and subband signal component, the value of the noise-to-signal ratio that meets a specified masking criterion is determined. The values from the combinations are stored. Then, a noise level vector for any other signal can be determined by filtering the signal into a set of components, accessing the stored values and combining the values to yield a measure of the masking properties of the other signal. <IMAGE>
