摘要： Binaural rendering a multi-channel audio signal into a binaural output signal (24) is described. The multi-channel audio signal comprises a stereo downmix signal (18) into which a plurality of audio signals are downmixed, and side information comprising a downmix information (DMG, DCLD) indicating, for each audio signal, to what extent the respective audio signal has been mixed into a first channel and a second channel of the stereo downmix signal (18), respectively, as well as object level information of the plurality of audio signals and inter-object cross correlation information describing similarities between pairs of audio signals of the plurality of audio signals. Based on a first rendering prescription, a preliminary binaural signal (54) is computed from the first and second channels of the stereo downmix signal (18). A decorrelated signal (Xn,kd) is generated as an perceptual equivalent to a mono downmix (58) of the first and second channels of the stereo downmix signal (18) being, however, decorrelated to the mono downmix (58). Depending on a second rendering prescription (P21,m), a corrective binaural signal (64) is computed from the decorrelated signal (62) and the preliminary binaural signal (54) is mixed with the corrective binaural signal (64) to obtain the binaural output signal (24).

摘要： A device for generating a binaural signal based on a multi-channel signal representing a plurality of channels and intended for reproduction by a speaker configuration having a virtual sound source position associated to each channel, is described. It comprises a correlation reducer for differently processing, and thereby reducing a correlation between, at least one of a left and a right channel of the plurality of channels, a front and a rear channel of the plurality of channels, and a center and a non-center channel of the plurality of channels, in order to obtain an inter-similarity reduced set of channels; a plurality of directional filters, a first mixer for mixing outputs of the directional filters modeling the acoustic transmission to the first ear canal of the listener, and a second mixer for mixing outputs of the directional filters modeling the acoustic transmission to the second ear canal of the listener. According to another aspect, a center level reduction for forming the downmix for a room processor is performed. According to even another aspect, an inter-similarity decreasing set of head-related transfer functions is formed.

摘要： An apparatus (100) for processing an input audio signal (122) for reproduction by a sound transducer (130) comprises an equalization parameter determinator (110) for determining a set of equalization parameters (112) and an equalizer (120) configured to equalize the input audio signal (122), to obtain an equalized audio signal (124). Different concepts for the determination of the set of equalization parameters (112) comprise an image recognition, an evaluation of an identification signal which is provided by the sound transducer via an audio connection, and a measurement of the impedance of the sound transducer over frequency. Also, an upload functionality and a download functionality are provided.
