  • Patent number: 11727950
    Abstract: Disclosed herein are new techniques carried out by a computing system for determining delays of various components of an audio system to allow for accurate correction of these delays, which may improve the audio quality of live performances for listeners who hear audio reproduced by loudspeakers at live performance venues. In one implementation the computing system, which may comprise a transmitter device and one or more receiver devices, may be configured to perform functions, including receiving a first audio signal, receiving, via an audio input interface of the receiver, a second audio signal, and determining, based on the first audio signal and the second audio signal, an audio delay that is associated with the second audio signal. The computing system may be configured to perform further functions, including based on a determined cross-correlation between a downsampled audio signal and a filtered second audio signal, determining the audio signal delay.

  • Patent number: 6356084
    Abstract: A cable tester is provided having a receive unit comprising a cylindrical housing with open ends, a connector which is attached to one open end, and a plurality of light-emitting diodes (LED's) which are mounted within the other end and are electrically connected to the connector. The connector is attached to the end of a cable to be tested. For cables having phantom power, the phantom power energizes the connector and LED's, and the LED's illuminate in a predetermined manner according to the operating condition of the cable. Utilizing the phantom power, the tester is able to indicate whether the cable being tested is functional and, if not, what specifically is wrong with the audio cable, even when only one end of the cable is accessible. In the event the cable does not have phantom power, and provided the other end is also accessible, the tester is further provided with a send unit having a voltage source which is connected to the other end of the cable.

  • Patent number: 6332188
    Abstract: A digital signal processor includes a computation block with an arithmetic logic unit, a multiplier, a shifter and a register file. The computation block includes a plurality of registers for storing instructions and operands in a bit format as a continuous bit stream, and utilizes a bit transfer mechanism for transferring in a single cycle a bit field of an arbitrary bit length between the plurality of registers and the shifter. The plurality of registers may be general purpose registers located in the register file. The register file may further include at least one control information register for storing control information used by the bit transfer mechanism.
