Patent number: 10986460Abstract: Example techniques relate to grouping based on acoustic signals in a system including a first network device and a second network device. A first network device may detect a first acoustic signal, perhaps while playing back first audio content in a single-device playback configuration.

Patent number: 10848897Abstract: An acoustic processing device performs acoustic processing in a space having a first listening position and a second listening position apart from the first listening position. The acoustic processing device includes a first input unit, a first output unit, and a signal processing circuit. The first input unit receives a first sound source signal to be reproduced at the first listening position. The first sound source signal includes a first left-channel signal and a first right-channel signal. The first output unit outputs the first sound source signal to a first speaker group including a first speaker disposed near a place of a head of a listener at the first listening position. The signal processing circuit draws out a first common signal common to both the first left-channel signal and the first right-channel signal and outputs the first common signal to the first speaker.Type: GrantFiled: September 20, 2019Date of Patent: November 24, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yasuhiro Koyama, Takashi Nakanishi, Hiroshi Tsukamoto

Patent number: 10839795Abstract: A user can utter a voice command in an environment where multiple audio playback devices are located to have audio output on a single device, or a predefined group of devices in a synchronized manner. In instances when the voice command uttered by the user does not specify a target for audio output, an implicit target selection algorithm can evaluate one or more criteria to determine an appropriate target for output of the audio corresponding to the voice command. An example criterion is met if a predetermined time period has lapsed since a last utterance was detected by a device in the environment. However, other criteria can be evaluated for determining a target output device(s).Type: GrantFiled: February 15, 2017Date of Patent: November 17, 2020Assignee: Amazon Technologies, Inc.Inventors: Fred Torok, Michael Alan Pogue, Vikram Kumar Gundeti, Dharini Sundaram

Patent number: 10841728Abstract: An audio system processes a multi-channel input audio signal into a stereo signal for left and right speakers, while preserving the spatial sense of the sound field of the input audio signal. The multi-channel input audio signal includes a first left-right channel pair including a left input channel and a right input channel, and a second left-right channel pair including a left peripheral input channel and a right peripheral input channel. Subband spatial processing may be applied to the first and second left-right channel pairs. A first crosstalk processing is applied to the first left-right channel pair to generate first crosstalk processed channels. A second crosstalk processing is applied to the second left-right channel pair to generate second crosstalk processed channels. A left output channel and a right output channel are generated from the first and second crosstalk processed channels. The crosstalk processing may include crosstalk cancellation or crosstalk simulation.Type: GrantFiled: October 10, 2019Date of Patent: November 17, 2020Assignee: Boomcloud 360, Inc.Inventor: Zachary Seldess

Patent number: 10824670Abstract: A digital media search and presentation service will receive audio streams from multiple audio content sources and capture text segments, each of which corresponds to words in a snippet of the audio stream. When a client device receives a search request, the service will identify text segments that correspond to the search request. The service will select one or more of the text segments as candidate search results. The service will cause the client device to output user-selectable fields, each of which includes information corresponding to the selected text segments in a user-selectable interface by which a user may select the audio content sources for each of the text segments. When a user selects one of the fields, a media player of the client device will access and play audio content that the audio content source is transmitting at the time.Type: GrantFiled: March 22, 2019Date of Patent: November 3, 2020Assignee: nedl.com, Inc.Inventors: Ayinde Alakoye, Jason Medeiros
