Method and hearing device for transmitting an audio signal from a transmitter to a receiver

A method for transmitting an audio signal from a transmitter to a receiver, which comprises the steps of:

• dividing an input signal corresponding to the audio signal into a number of frequency channels for a particular time window, at a transmitter end;
• allocating a current channel value to each frequency channel at the transmitter end;
• dividing current channel values into a first current data record and a second current data record, at the transmitter end;
• generating a first forecast for the first current data record by means of a channel value preceding in time at the transmitter end;
• determining a first deviation between the first forecast and the first current data record at the transmitter end;
• generating a second forecast for the second current data record by means of the first current data record, at the transmitter end;
• determining a second deviation between the second forecast and the second current data record at the transmitter end;
• transmitting a first transmission value corresponding to the first deviation from the transmitter to the receiver;
• transmitting a second transmission value corresponding to the second deviation from the transmitter to the receiver;
• generating a first reconstructed data record by means of a reconstructed output signal preceding in time and the first transmission value, at a receiver end;
• generating a second reconstructed data record by means of the first reconstructed data record and the second transmission value at the receiver end;
• and
• combining the first reconstructed data record and the second reconstructed data record to form a reconstructed output signal at the receiver end.
