  • Patent number: 11533576
    Abstract: A method for generating sound within a predetermined environment, the method comprising: emitting a first audio signal from a first location; and concurrently emitting a second audio signal from a second location, wherein: the first location and second location are distinct within the environment; the first audio signal and second audio signal have the same frequency; and the first audio signal and second audio signal have a phase difference that varies as a function of time to limit the time-averaged interference fluctuation across the environment.
    Type: Grant

  • Patent number: 11350229
    Abstract: A method for determining an actual position of a microphone, comprising: sequentially emitting a first sound signal via a first speaker positioned and a second sound signal via a second speaker positioned; measuring a first elapsed time between the emission of the first sound signal and a detection of the first sound signal by the microphone, and a second elapsed time between the emission of the second sound signal and a detection of the second sound signal by the microphone; determining a first distance between the first speaker and the microphone using the first elapsed time, and a second distance between the second speaker and the microphone using the second elapsed time; determining the actual position of the microphone using the first and second distances and the positions of the first and second speaker; and outputting the actual position.

  • Patent number: 10291999
    Abstract: A method comprising: receiving a reference time delay between a first reference signal emitted by a first speaker and a second reference signal emitted by a second speaker, each recorded by a microphone having a target position; using the microphone positioned at an actual position, recording a first sound signal emitted by the first speaker and a second sound signal emitted by the second speaker; determining an actual time delay between the first and second sound signals; comparing the actual time delay to the reference time delay; determining a match or a mismatch between the actual position and the target position for the given microphone; and outputting an indication of the match/mismatch.

  • Patent number: 10165385
    Abstract: A system for generating calibrated multi-channel non-coherent signals. The system comprises a plurality of synthesizers for generating a corresponding plurality of signals, and a plurality of filters for band-pass filtering the plurality of generated signals. Each filter filters the signal generated by one of the plurality of synthesizers, by performing the band-pass filtering in a dedicated frequency band. The system comprises a plurality of loudspeakers for playing the plurality of filtered signals respectively filtered by the plurality of filters. The system comprises a channel configurator for configuring at least one of the filters for performing the band-pass filtering according to a calibrated amplitude spectrum of the signal.

  • Patent number: 10158961
    Abstract: There is described a computer-implemented method for calibrating a sound signal, comprising: receiving an initial sound signal, a recorded background sound signal, a recorded initial sound signal and a target sound signal; subtracting the recorded background sound signal from the recorded initial sound signal, thereby obtaining a denoised sound signal; dividing the target sound signal by the denoised sound signal, thereby obtaining a compensation factor; dividing the initial sound signal by the compensation factor, thereby obtaining a calibrated sound signal; and outputting the calibrated sound signal.
