ABSTRACT:
A signal processing apparatus and method decodes codes generated by encoding decomposed frequency components, and combines frequency components obtained in the decoding to form a waveform signal. The apparatus and method further monitors a processing condition in the decoding, and controls a processed band of the waveform signal, formed in the combining, in accordance with the monitoring result obtained in the monitoring.
