Method and devices for providing surround audio signals are provided. Surround audio signals are received and are binaurally filtered by at least one filter unit. In some embodiments, the input surround audio signals are also processed by at least one equalizing unit. In those embodiments, the binaurally filtered signals and the equalized signals are combined to form output signals.

Methods and devices for reproducing surround audio signals

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.
