摘要： Masking thresholds are obtained for each frequency component of sound data and ambient noise. It is determined whether each frequency component of the sound data is masked by at least one of the other frequency components of the sound data. It is further determined whether each frequency component of the sound data is masked by ambient noise. Correction coefficients are set for each frequency component of the sound data according to whether the frequency component is masked by at least one of the other frequency components of the sound data and whether the frequency component is masked by the ambient noise. And each frequency component of the sound data is corrected by using the respective correction coefficients.

摘要： Activity is determined for each frequency band in a frame, and when it is determined that an activity-OFF state has not continued for a predetermined number of times for preceding frames, normal coding processing is performed for the frequency band. When it is determined that the activity-OFF state has continued for the predetermined number of times or more, DTX coding is performed for the frequency band. After this processing has been performed for all of the bands of one frame, a total power of the one entire frame and the power of the band or bands to which the DTX coding is applied are calculated. Subsequently, a new target bit value is calculated based on a ratio of the total power of the one entire frame and the power of the band or bands to which the DTX coding is applied.
