  • Publication number: 20210227327
    Abstract: In general, the present invention relates to a method and apparatus for estimating spatial content of a soundfield at a desired location, including a location that has actual sound content obstructed or distorted. According to certain aspects, the present invention aims at presenting a more natural, spatially accurate sound, for example to a user at the desired location who is wearing a helmet, mimicking the sound a user would experience if they were not wearing any headgear. Modes for enhanced spatial hearing may be applied which would include situation-dependent processing for augmented hearing. According to other aspects, the present invention aims at remotely reproducing the soundfield at a desired location with faithful reproduction of the spatial content of the soundfield.

  • Patent number: 11049482
    Abstract: In general, the present invention relates to a method and system for synthesizing artificial reverberation using modal analysis of a room or resonating object. In one embodiment of the inventive system, a collection of resonant filters is employed, each driven by the source signal, and their outputs summed. With filter resonance frequencies and dampings tuned to the modal frequencies and decay times of the acoustic space or resonating object being simulated, and filter gains set according to the source and listener positions within the space or object, any number of acoustic spaces and resonant objects may be simulated.

  • Publication number: 20210037316
    Abstract: The present embodiments generally relate to enabling participants in an online gathering with networked audio to use a cancelling auralizer at their respective locations to create a common acoustic space or set of acoustic spaces shared among subgroups of participants. For example, there are a set of network connected nodes, and the nodes can contain speakers and microphones, as well as participants and node mixing-processing blocks. The node mixing-processing blocks generate and manipulate signals for playback over the node loudspeakers and for distribution to and from the network. This processing can include cancellation of loudspeaker signals from the microphone signals and auralization of signals according to control parameters that are developed locally and from the network.

  • Patent number: 10812902
    Abstract: A method and system for real-time auralization is described in which room sounds are reverberated and presented over loudspeakers, thereby augmenting the acoustics of the space. Room microphones are used to capture room sound sources, with their outputs processed in a canceler to remove the synthetic reverberation also present in the room. Doing so gives precise control over the auralization while suppressing feedback. It also allows freedom of movement and creates a more natural acoustic environment for performers or participants in music, theater, gaming, home entertainment, and virtual reality applications. Canceler design methods are described, including techniques for handling varying loudspeaker-microphone transfer functions such as would be present in the context of a performance or installation.

  • Patent number: 10559295
    Abstract: In music recording and virtual reality applications, it is desired to control the perceived size of a synthesized acoustic space. In an embodiment, a room size parameter is used to modify characteristics of an artificial reverberator so as to affect a listener's sense of the size of the acoustic space. Properties of the reverberation related to perceived room size such as decay time and equalization are adjusted interactively.

  • Patent number: 10405104
    Abstract: The invention includes a basic approach to simulate the workings of a ribbon microphone based on measurements at an array of more robust small pressure microphones. Embodiments of the invention take an array of microphone elements, either very small microphones that are placed on either side of a printed circuit board or some other device to understand the sound pressure differences from front to back and use those sound pressure differences to emulate the motion of a ribbon if a ribbon were co-located with the array of microphones. The microphone array detects differential pressure, either by a set of elements that that have figure of eight polar patterns, or by having separate elements front and back.

  • Patent number: 10338246
    Abstract: In the field of seismic data analysis, the problem of estimating features of a microseismic event waveform, detected at the sensors of a geophone array in the presence of background seismic energy and sensor noise, is considered. Embodiments of the present disclosure provide a method and system for estimating wavefront arrival times and polarizations across the sensors of an array, while simultaneously extracting the associated event sensor waveforms from the seismic background. The resulting waveform estimates are estimated in such a way that estimation errors are expected to be noise-like, and free of any systematic changes in the magnitude or phase of the arriving wavefronts.

  • Patent number: 10199024
    Abstract: Methods and apparatuses according the present embodiments derive the sound of a Hammond tonewheel organ from the equal-tempered tuning of its tonewheels and drawbar registration design, as well as its vibrato/chorus processing and pickup distortion. In embodiments, as a reverberation effect, the modal processor simulates a room response as the sum of resonant filter responses, providing precise, independent and interactive control over the frequency, damping, and complex amplitude of each mode. As an effects processor, the modal processor provides pitch shifting and distortion by simple manipulations of the mode output sinusoids.

  • Publication number: 20160140950
    Abstract: A method or system is provided for real-time synthesis in a rehearsal space of an acoustic environment of a target space. Microphones, pick-ups or other devices are used to separately record the singing or instruments. These “dry” instrument signals are sent to a remote site, where they are processed to imprint the acoustics of the desired location. Performers in a rehearsal space with loudspeakers are close-miked. The signals collected would be sent to a processing center via a low-latency internet connection, where the signals would be processed according to the response of the target acoustic space, corrected by the known acoustics and loudspeaker configuration of the rehearsal space. The processed signals would then be sent back to the rehearsal space, where they would be amplified and played over the loudspeakers, thereby giving the impression that the performers are performing in the target acoustic space.

  • Patent number: 8391504
    Abstract: The present invention relates to audio signal processing, and more particularly to methods and apparatuses for emulating and controlling various features of mechanical spring reverberation in a digital audio processing system. According to certain aspects of the invention, such an emulation is performed so as to enhance or alter the characteristics of a digitally stored or processed audio signal in substantially the same manner as a mechanical spring reverberation system. In one example embodiment, the propagation of energy through a mechanical spring is simulated using dispersive waveguides, wherein left-going and right-going waves are separately processed, and the effects of dispersion and attenuation commuted to the waveguide ends. According to additional aspects, many spring reverberators contain spring elements arranged in parallel, with no coupling between springs.

  • Patent number: 8014541
    Abstract: A system and method for graphic equalization of audio signals is disclosed. Traditional graphic equalizers provide control over the gains in each of a set of frequency bands. However, the actual band gains vary from the desired gains due to crosstalk between bands. Prior art methods for addressing this difficulty include applying a correction filter to the equalizer, and adjusting the shape of the individual band filters, both of which increase the computational cost. In an embodiment of the present invention, the input gains are processed to produce a set of adjusted gains which take into account the crosstalk, and result in an equalization interpolating the input band gains.
