摘要： Systems and methods for determining a virtual sound source position by determining an output for loudspeakers by the position of the loudspeakers in relation to a listener. The output of respective loudspeakers is generated using aural cues to give the listener knowledge of the virtual position of the virtual sound source. Both a gain in intensity and a delay are simulated.

摘要： A technique for the masking of quantizing noise in the coding of audio signals is usable with the types of channel coding known as "noiseless" or Huffman coding and with variable radix packing. In a multichannel environment, noise masking thresholds may be determined by combining sets of power spectra for each of the channels. The stereophonic embodiment eliminates redundancies in the sum and difference signals, so that the stereo coding uses significantly less than twice the bit rate of the comparable monaural signal. The technique can be used both in transmission of signals and in recording for reproduction, particularly recording and reproduction of music. Compatibility with the ISDN transmission rates known as 1B, 2B and 3B rates has been achieved.

摘要： An image-coding system reduces image data redundancies and perceptual irrelevancies through progressive sub-band coding. The image is separated into a plurality of sub-bands. From this sub-band information, a perceptual metric, based on the properties of the sub-band filters, quantizer error distribution, and properties of the human visual system, is determined which provides the maximum amount of coding noise that may be introduced to each pixel in every sub-band without causing perceptible degradation of the coded image. This perceptual metric is used to adjust the quantizer used in encoding each sub-band signal. In addition, redundancy in the output of the quantizer is reduced using a multidimensional Huffman compression scheme.

摘要： A method and apparatus processes multi-channel audio by encoding, transmitting or recording “dry” audio tracks or “stems” in synchronous relationship with time-variable metadata controlled by a content producer and representing a desired degree and quality of diffusion. Audio tracks are compressed and transmitted in connection with synchronized metadata representing diffusion and preferably also mix and delay parameters. The separation of audio stems from diffusion metadata facilitates the customization of playback at the receiver, taking into account the characteristics of local playback environment.

摘要： A speaker virtualization system provides virtual surround sound using a pair of physical loudspeakers. A multiple surround audio channels input is processed using a combination of head related transfer functions and shaped reverberation to provide widening and front/back auditory clues without requiring any kind of interaural path cancellation. The system uses a 360 degree power-response head related transfer function to provide perceptual separation of the reverberant and direct paths, along with discrete, different reverberation for left and right rendering channels to provide envelopment. By eliminating interaural path cancellation, the speaker virtualization system also produces a wider virtual surround sound effect, without dependency on head position and facing.
