Abstract
A data processing apparatus includes an input terminal for receiving an audio signal, a 1-bit A/D converter for A/D converting the audio signal so as to obtain a bitstream signal, and a prediction unit for carrying out a prediction step on the bitstream signal so as to obtain a predicted bitstream signal. The data processing apparatus further includes a signal combination unit for combining the bitstream signal and the predicted bitstream signal so as to obtain a residue bitstream signal, and an output terminal for supplying the residual bitstream signal. A recording apparatus or a transmitter apparatus can use the data processing apparatus.
