发明名称 Determining a masking level for a subband in a subband audio encoder
摘要 The first step for calculating a signal-to-mask ratio (806) for a subband in a subband in a subband audio encoder is calculating a signal level for each of the subbands based on an audio frame (604). Then, the masking level is calculated for the particular subband based on the signal levels, an offset function, and a weighting function (606).
