<p>A transmitter is disclosed for transmitting an audio signal. The transmitter comprises an input terminal (1) for receiving the audio signal, a 1-bit A/D converter (4) for A/D converting the audio signal so as to obtain a bitstream signal, a prediction unit (10) for carrying out a prediction step on the bitstream signal so as to obtain a predicted bitstream signal, a signal combination unit (42) for combining the bitstream signal and the predicted bitstream signal so as to obtain a residue bitstream signal, data compression means (154) for data compressing the residual bitstream signal so as to obtain a data compressed residual bitstream signal, and transmission means for applying the data compressed residual bitstream signal to a transmission medium (Figure 1 and 5). Further, a corresponding recording apparatus (Figure 1 and 4) is disclosed.</p><p>In addition, another embodiment (Figure 7) for converting the residue bitstream signal into an audio signal is disclosed, as well as a reproducing apparatus (Figure 9) and a receiver apparatus (Figure 10) comprising the other embodiment.
