Abstract:
1. An electronic device comprising: an input data interface for receiving digital audio data; a memory storing dimensions of a virtual room in which the digital audio data is to be emitted, the virtual room having a plurality of virtual surfaces; a digital reverberator for simulating the sound of the digital audio data in the virtual room, the digital reverberator comprising: an output data interface for receiving the digital audio output signal and outputting an audio signal; wherein each delay line connecting the source injection node with a respective junction comprises a source unidirectional delay line in the direction from the source injection node to the junctions, each source unidirectional delay line having a separate injection point in the digital reverberation network through which digital audio data is input; and wherein each delay line connecting junctions of the digital reverberation network with the receiver node comprises a receiver unidirectional delay line in the direction from the junctions to the receiver node, each receiver unidirectional delay line having a separate extraction point in the digital reverberation network through which digital audio data is extracted.
