Abstract
Every extreme value in an audio waveform represented by a digital audio signal having a sequence of samples is detected. A number of samples between samples corresponding to the first and second latest extreme values is detected. A corrective value is generated in response to the detected sample number and a difference between the first and second latest extreme values. Ones are designated among samples in response to the detected sample number. The designated samples include at least (1) a sample adjacently following the sample corresponding to the second latest extreme value, (2) a sample adjacently preceding the sample corresponding to the first latest extreme value, and (3) one of the sample corresponding to the first latest extreme value and the sample corresponding to the second latest extreme value. The designated samples are corrected in response to at least one of current, previous, and feature corrective values.
