Patent number: 11395083Abstract: In general, techniques are described by which to support scalable unified audio rendering. A device comprising an audio decoder, a memory, and a processor may be configured to perform various aspects of the techniques. The audio decoder may decode, from a bitstream, first audio data and second audio data. The memory may store the first audio data and the second audio data. The processor may render the first audio data into first spatial domain audio data for playback by virtual speakers at a set of virtual speaker locations, and render the second audio data into second spatial domain audio data for playback by the virtual speakers at the set of virtual speaker locations. The processor may also mix the first spatial domain audio data and the second spatial domain audio data to obtain mixed spatial domain audio data, and convert the mixed spatial domain audio data to scene-based audio data.Type: GrantFiled: January 31, 2019Date of Patent: July 19, 2022Assignee: QUALCOMM IncorporatedInventors: Andre Gustavo P. Schevciw, Nils Günther Peters

Patent number: 9305567Abstract: A method for signal level matching by an electronic device is described. The method includes capturing a plurality of audio signals from a plurality of microphones. The method also includes determining a difference signal based on an inter-microphone subtraction. The difference signal includes multiple harmonics. The method also includes determining whether a harmonicity of the difference signal exceeds a harmonicity threshold. The method also includes preserving the harmonics to determine an envelope. The method further applies the envelope to a noise-suppressed signal.Type: GrantFiled: March 14, 2013Date of Patent: April 5, 2016Assignee: QUALCOMM IncorporatedInventors: Erik Visser, Lae-Hoon Kim, Jongwon Shin, Yinyi Guo, Sang-Uk Ryu, Andre Gustavo P.

Patent number: 9262002Abstract: A computing device includes a touch screen display with a plurality of force sensors, each of which provides a signal in response to contact with the touch screen display. Using force signals from the plurality of force sensors, a characteristic of the contact is determined, such as the magnitude of the force, the centroid of force and the shear force. The characteristic of the contact is used to select a command which is processed to control the computing device. For example, the command may be related to manipulating data displayed on the touch screen display, e.g., by adjusting the scroll speed or the quantity of data selected in response to the magnitude of force, or related to an operation of an application on the computing device, such as selecting different focal ranges, producing an alarm, or adjusting the volume of a speaker in response to the magnitude of force.Type: GrantFiled: November 3, 2010Date of Patent: February 16, 2016Assignee: QUALCOMM IncorporatedInventors: Brian Momeyer, Kevin M. Beckwith, Hui-Ya L. Nelson, Andre Gustavo P. Schevciw, Louis Dominic Oliveira, Wade L. Heimbigner, Babak Forutanpour

Patent number: 9066170Abstract: A mobile platform includes a microphone array and is capable of implementing beamforming to amplify or suppress audio information from a sound source. The sound source is indicated through a user input, such as pointing the mobile platform in the direction of the sound source or through a touch screen display interface. The mobile platform further includes orientation sensors capable of detecting movement of the mobile platform. When the mobile platform moves with respect to the sound source, the beamforming is adjusted based on the data from the orientation sensors so that beamforming is continuously implemented in the direction of the sound source. The audio information from the sound source may be included or suppressed from a telephone or video-telephony conversation. Images or video from a camera may be likewise controlled based on the data from the orientation sensors.Type: GrantFiled: July 30, 2013Date of Patent: June 23, 2015Assignee: QUALCOMM IncorporatedInventors: Babak Forutanpour, Andre Gustavo P. Schevciw, Erik Visser, Brian Momeyer

Patent number: 8855322Abstract: An original loudness level of an audio signal is maintained for a mobile device while maintaining sound quality as good as possible and protecting the loudspeaker used in the mobile device. The loudness of an audio (e.g., speech) signal may be maximized while controlling the excursion of the diaphragm of the loudspeaker (in a mobile device) to stay within the allowed range. In an implementation, the peak excursion is predicted (e.g., estimated) using the input signal and an excursion transfer function. The signal may then be modified to limit the excursion and to maximize loudness.Type: GrantFiled: August 9, 2011Date of Patent: October 7, 2014Assignee: QUALCOMM IncorporatedInventors: Sang-Uk Ryu, Jongwon Shin, Roy Silverstein, Andre Gustavo P. Schevciw, Pei Xiang

Publication number: 20130040694Abstract: Methods, systems and devices enabling a party to a telephone conversation to identify sounds for active filtering so that the identified sound can be actively filtered and/or amplified. Cell phones are provided with a button that allows users to identify sounds for filtering by pressing the button or virtual key when the sound is heard. Sounds recorded in response to such user inputs are processed to identify filtering criteria, such as frequencies and amplitude. The identified filtering criteria are then used to actively filter or enhance sounds. The methods and systems enable user to identify specific sounds for filtering so only those sounds deemed annoying are suppressed while permitting other sounds (e.g., voice) to be heard.Type: ApplicationFiled: August 10, 2011Publication date: February 14, 2013Inventors: Babak FORUTANPOUR, Erik VISSER, Brian MOMEYER, Andre Gustavo P.

Publication number: 20120051555Abstract: A method for adjusting volume in a headset based on accumulated acoustic energy density exposure is disclosed. A sound pressure value of a microphone positioned in a user's ear canal is measured. A current accumulated acoustic energy density exposure is determined based on sound pressure values measured during the rolling window. The maximum volume in the headset is adjusted based on a comparison of the current accumulated energy density exposure to a predetermined threshold.Type: ApplicationFiled: August 23, 2011Publication date: March 1, 2012Applicant: QUALCOMM IncorporatedInventors: Andre Gustavo P.
