ABSTRACT:
An audio signal encoder is provided which is designed to A/D-convert an analog input signal at a first sampling frequency without being compressed and at a second sampling frequency that is two or four times higher than the first sampling frequency in data compression for minimizing data compression-caused errors in high-frequency components encoded. A decoder decoding digital signals produced by the encoder and a record carrier storing therein the digital signals are also provided.
