Beschreibung
Zusammenfassung:	An audio signal processing device comprises: an audio input configured to receive an audio signal to be coded; an audio codec configured to apply audio coding to the audio signal, thereby generating coded audio data, having an audio bandwidth, for transmission to a remote device; a network interface configured to receive from the remote device an indication of at least one characteristic of an audio output device of the remote device; and an audio bandwidth selector configured to set an audio bandwidth parameter of the audio codec based on the indication received from the remote device, thereby setting the audio bandwidth of the coded audio data in dependence on the at least one characteristic of the audio output device.
