| Zusammenfassung: | A device which produces the necessary directional audio signals for a 3-dimensional audio playback and which in that case uses as input signals the available channels of an audio recording intended for 2-dimensional audio playback. By taking psychoacoustic effects into account the desired spatial 3D audio effect is produced by a targeted use of signal delays, frequency-dependent amplitude matchings and a limited use of reverberation effects in conjunction with a targetedly asymmetric processing. |
