摘要： Six input channels, to which are allocated 5.1-channel surround signals from a plurality of input sources, are grouped into a surround channel group, and these six input channels are connected to corresponding ones of six surround buses in a one-to-one relationship. Thus, merely grouping the input channels into a surround channel group allows the signals of the individual input channels (5.1-channel surround signals) to be taken out via a plurality of output destinations (5.1-channel speakers) corresponding to the surround buses. Once an instruction is given for changing a value of a parameter, the parameter is controlled in a ganged fashion in all of the input channels of the surround channel group except for an LFE input channel of the surround channel group.

摘要： A method for headphone reproduction of at least two input channel signals is proposed. Said method comprises for each pair of input channel signals from said at least two input channel signals the following steps. First, a common component, an estimated desired position corresponding to said common component, and two residual components corresponding to two input channel signals in said pair of input channel signals are determined. Said determining is being based on said pair of said input channel signals. Each of said residual components is derived from its corresponding input channel signal by subtracting a contribution of the common component. Said contribution is being related to the estimated desired position of the common component. Second, a main virtual source comprising said common component at the estimated desired position and two further virtual sources each comprising a respective one of said residual components at respective predetermined positions are synthesized.

摘要： A surround sound processor system (108) for multichannel redistribution of stereophonic signals (2, 4) has digitally controlled gains in each input and each output channel, controlled by a microprocessor (51), which receives an input signal from a microphone (74) placed at the preferred listening location within the listening area (72) for automatically balancing the input signals (2, 4) and setting both input and output gains during a calibration process so as to provide the listener with the best possible surround sound reproduction of the stereophonic source material. As a visual aid, the microprocessor displays menus and messages on a video screen (78), and a visual display (88) shows the relative levels of the six axes of control signals within the surround sound processor.

摘要： An audio encoder comprises a multi-channel receiver (401) which receives an M-channel audio signal where M>2. A down-mix processor (403) down-mixes the M-channel audio signal to a first stereo signal and associated parametric data and a spatial processor (407) modifies the first stereo signal to generate a second stereo signal in response to the associated parametric data and spatial parameter data for a binaural perceptual transfer function, such as a Head Related Transfer Function (HRTF). The second stereo signal is a binaural signal and may specifically be a (3D) virtual spatial signal. An output data stream comprising the encoded data and the associated parametric data is generated by an encode processor (411) and an output processor (413). The HRTF processing may allow the generation of a (3D) virtual spatial signal by conventional stereo decoders. A multi-channel decoder may reverse the process of the spatial processor (407) to generate an improved quality multi-channel signal.

摘要： Disclosed is a device for processing an input signal comprising a number of sub-signals which are allocated to discrete transmitting and receiving units that are disposed in predetermined geometrical positions relative to a space. The inventive device encompasses an apparatus (101) for supplying a plurality of wavefield components, the superposition of which results in a combined wavefield that is expandable in said space, the plurality of wavefield components being derived from the input signal by dividing the wavefield based on orthogonal basic wavefield functions and the predetermined geometrical positions. The inventive device further encompasses a plurality (107) of individual filters, one of the plurality of wavefield components being associated with an individual filter. The individual filter is configured to influence the associated wavefield components such that a plurality of filtered wavefield components representing a processed input signal are obtained relative to the plurality of individual filters (107) at the output end.

摘要： A method and circuit for deriving a set of multichannel audio signals (10) from a conventional monaural or stereo audio signals (1) uses an auxiliary multichannel spectral mapping data steam (90,92). Audio can be played back in stereo and multichannel formats from a conventional stereo signal (40) on compact discs (88), FM radio, or other stereo or monaural delivery systems (5). The invention reduces the data rate needed for the transmission of multichannel digital audio.

摘要： A sound processing system (202) for a vehicle includes a sound processor (402) that is configured to mix at least one real audio input signal (212) to form at least one virtual output signal (408). At least one audio signal that is available to drive at least one loudspeaker may be formed using the combination of the virtual output signal (408) and the real audio input signal (212). The virtual output signal (408) may be post processed to form a predetermined frequency range of the audio signal prior to being combined with the real audio input signal. The audio signal may be created by mixing the real audio input signal with the post processed virtual output signal. Alternatively, the audio signal may be formed by mixing the real audio input signal to form a real audio output signal, and then summing the real audio output signal with the post processed virtual output signal (424). Mixing may be performed with a crossbar mixer (302) included in the sound processor.
