Publication number: 20230209256Abstract: 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.Type: ApplicationFiled: February 17, 2023Publication date: June 29, 2023Applicants: The Board of Trustees of the Leland Stanford Junior University, University of LimerickInventors: Jonathan S.

Publication number: 20220386063Abstract: In general, the present embodiments relate 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 embodiments aim 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, methods and apparatuses record or capture the sound experienced by a number of the participants and devices on and near the field of play, analyze the captured sound for its various components and their associated spatial content, and make those components available to participants and spectators.Type: ApplicationFiled: April 14, 2022Publication date: December 1, 2022Inventors: Jonathan S.

Publication number: 20220381933Abstract: In the field of seismic data collection and analysis, the problem of data compression is considered. It is desired to reduce the storage and transmission requirements of seismic data, such as associated with microseismic monitoring and processing, VSP (vertical seismic profile) surveys, and the like, for instance using a distributed acoustic sensor (DAS), which can generate in excess of 50 GB of data per hour on a survey that lasts days. A method and system for data compression that separates the data collected into additive signal and noise components, and compresses the estimated signal component for transmission, storage, and analysis, is described. The idea is that the signal component, which exhibits clear structure across the traces, may be accurately described with relatively few parameters, and therefore may be significantly compressed without loss of important information.Type: ApplicationFiled: February 9, 2022Publication date: December 1, 2022Applicant: Seismic Services LLCInventors: Jonathan S.

Patent number: 10812902Abstract: 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.Type: GrantFiled: June 14, 2019Date of Patent: October 20, 2020Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Jonathan S.

Patent number: 10559295Abstract: 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.Type: GrantFiled: December 7, 2018Date of Patent: February 11, 2020Inventor: Jonathan S.

Patent number: 10405104Abstract: 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.Type: GrantFiled: September 1, 2011Date of Patent: September 3, 2019Inventor: Jonathan S.

Patent number: 10338246Abstract: 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.Type: GrantFiled: August 30, 2016Date of Patent: July 2, 2019Assignee: Seismic InnovationsInventors: Jonathan S.

Patent number: 10199024Abstract: 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.Type: GrantFiled: May 31, 2017Date of Patent: February 5, 2019Inventors: Jonathan S.
