    摘要: The system and method of the present invention provides enhanced surround sound effects. In one embodiment, 90.degree. phase shift and copy of the modified head related transfer functions (HRTF) are applied to each rear sound signal. The modified HRTF for each rear signal is generated by removing the head related transfer function corresponding to the front center signal from the HRTF corresponding to the rear sound signal. This provides the audible effect of distinguishing more clearly sounds originating in front of the listener or to the rear of the listener while not limiting the perceived bandwidth of the signal. The rear signals corresponding to the first channel are inverted. The front and rear signals for each corresponding channel are then combined. The two channels, generated can be stored on media, such as film, and subsequently read and input to a surround sound decoder to generate enhanced surround sound output.

    摘要: A method and apparatus for reading digital audio signals photographically recorded on a medium (such as motion picture film). If the medium has multiple, spatially separated digital and analog audio soundtracks, a photosensitive detector array is employed for each of the digital audio soundtrack areas, and a separate analog soundtrack read head is employed. Preferably, digital error code is recorded in a digital soundtrack area of the medium (with digital audio bits), and error detection and correction are performed on the recorded digital audio bits read from the medium. Preferably, the apparatus includes switching circuitry for substituting a corresponding analog audio signal for one or more corrupted digital soundtrack channels, when such digital soundtrack channels have an error rate which exceeds a selected threshold. Also preferably, the invention reads recorded digital audio information by projecting a laser beam (having a near infrared wavelength) on a row of a digital soundtrack area of a motion picture film, to modulate the beam as it passes through the row. The radiation transmitted through each digital soundtrack bit area is projected onto a spot in the detector plane that is substantially larger than the dimension of each individual detector which receives the spot. As the film translates continuously relative to the radiation source so that the projection of the spot translates relative to each receiving detector, the output of each receiving detector is integrated over the period during which a portion of the spot is projected thereon.

    摘要: A method and apparatus for photographically recording digital audio signals, and a medium having digital audio signals photographically recorded thereon. In a preferred embodiment, a motion picture film recorded in accordance with the invention has multiple digital audio soundtracks and an analog audio soundtrack photographically recorded thereon. Two or more channels of digital audio information can be recorded in each digital soundtrack, along with additional digital information for clocking, tracking, and error detection and correction. Each digital soundtrack is recorded in an array of bit areas arranged in row and column order. In a class of preferred embodiments, each row of digital audio bits is recorded simultaneously by exposing the film to radiation that has been modulated by a linear shutter array. The radiation transmitted by each shutter array is projected onto a row of spots. Each spot covers the full width of one of the bit areas in a row, but only part of the length of the bit area. As the medium is translated continuously (lengthwise) relative to the projected spots, each of the spots sweeps across a bit area, thereby recording a bit in the bit area which it sweeps in a manner analogous to painting the bit area with a paint brush.

    摘要: The process involves subjecting finely divided particles of copper-bearing mineral sulphide ores or concentrates to a first stage leach in which the particles are leached in an aqueous ammoniacal ammonium carbonate solution in the presence of free oxygen to provide a first stage leach slurry which contains dissolved copper values. Residue is separated from the first stage leach slurry and is subjected to attrition in order to rub off an outer layer therefrom and expose surfaces of the residue beneath the layer. The resulting residue is passed to a second stage leach which is carried out in the same way as the first leach. Solution is removed from the second leach stage and is recycled to the first leach stage. The first stage leach solution is further treated for recovery of copper and ammonium sulphate.
