Abstract
The invention provides a sound-reproducing apparatus and a high frequency interpolation-processing method in each of which high frequency interpolation processing having a light burden imposed thereon can be executed. Compressed audio data is decoded by a decoder () and the resulting audio signal is transmitted to a harmonizer (). Auxiliary information such as a sampling rate and a bit rate contained in the decoded audio signal is read out by a header reader () and is transmitted to a harmonizer (). Communication of signals from/to respective portions is made through a bus (). The harmonizer () has a preset for an interpolation band obtained in accordance with a format and a sampling frequency of the compressed audio data, and executes processing by referring to file information transmitted thereto from the header reader ().
