ABSTRACT:
A data processing apparatus for data processing an audio signal includes an input terminal (1) for receiving the audio signal, a 1-bit A/D converter (4) for A/D converting the audio signal to for a bitstream signal, a prediction unit (10) for carrying out a prediction step on the bitstream signal to form a predicted bitstream signal, a signal combination unit (42) for combining the bitstream signal and the predicted bitstream signal to form a residue bitstream signal, and an output terminal (14) for supplying the residual bitstream signal.
