Publication number: 20240236567Abstract: In general, this disclosure describes various aspects of the techniques directed to an adaptive audio system for occupant aware vehicles. A device configured to reproduce a soundfield based on audio data within a vehicle may implement the techniques. The device may comprise a memory configured to store the audio data, and processing circuitry coupled to the memory. The processing circuitry may be configured to obtain, from an occupant monitoring system, a state of an occupant residing within a cabin of the vehicle, modify, based on the state of the occupant residing within the cabin of the vehicle, playback of the audio data within at least a portion of the cabin of the vehicle to obtain modified playback data for the audio data, and reproduce, based on the modified playback data, the soundfield.Type: ApplicationFiled: September 20, 2023Publication date: July 11, 2024Inventors: Asif Mohammad, Laxmi Rayapudi, Eddie Choy

Patent number: 11031026Abstract: Methods, systems, computer-readable media, and apparatuses for acoustic echo cancellation during playback of encoded audio are presented. In some embodiments, a decoder is arranged to decode an encoded media signal to produce an echo reference signal, and an echo canceler is arranged to perform an acoustic echo cancellation operation, based on the echo reference signal, on an input voice signal to produce an echo-cancelled voice signal. The echo canceler may be configured to reduce, relative to an energy of a voice component of the input voice signal, an energy of a signal component of the input voice signal that is based on audio content from the encoded media signal.Type: GrantFiled: December 13, 2018Date of Patent: June 8, 2021Assignee: Qualcomm IncorporatedInventors: Andrew Kostic, Eddie Choy, Dinesh Ramakrishnan

Publication number: 20070244695Abstract: In a device configurable to encode speech performing an closed loop re-decision may comprise representing a speech signal by amplitude components and phase components for a current frame and a past frame. In a first closed loop stage, a first set of compressed components and a first set of uncompressed components for a current frame may be generated. A first set of features may be generated by comparing current and past frame amplitude and/or phase components. In a second closed loop stage, a second set of compressed components for the current frame may be generated by compressing the first set of compressed components and compressing the first set of uncompressed components. Generation of a second set of features may be based on the second set of compressed components from the current frame and a combination of amplitude and/or phase components from the past frame.Type: ApplicationFiled: January 22, 2007Publication date: October 18, 2007Inventors: Sharath Manjunath, Ananthapadmanabhan Kandhada, Eddie Choy

Publication number: 20070219787Abstract: In a device configurable to encode speech performing an open loop re-decision may comprise representing a speech signal by amplitude components and phase components for a current frame and a past frame. During the current frame, there may be an extraction of uncompressed amplitude components and uncompressed phase components. The amplitude components and the phase components from the past frame may then be retrieved. A set of features may be generated based on the uncompressed amplitude components from the current frame, the uncompressed phase components from the current frame, the amplitude components from the past frame, and the phase components from the past frame. The set of features may be checked as part of the open loop re-decision, and determining a final encoding decision based on the checking may be performed. The final encoding decision may be an encoding mode and/or encoding rate.Type: ApplicationFiled: January 22, 2007Publication date: September 20, 2007Inventors: Sharath Manjunath, Ananthapadmanabhan Kandhadai, Eddie Choy

Publication number: 20070094009Abstract: Encoder-assisted frame loss concealment (FLC) techniques for decoding audio signals are described. A decoder may discard an erroneous frame of an audio signal and may implement the encoder-assisted FLC techniques in order to accurately conceal the discarded frame based on neighboring frames and side-information transmitted from the encoder. The encoder-assisted FLC techniques include estimating magnitudes of frequency-domain data for the frame based on frequency-domain data of neighboring frames, and estimating signs of the frequency-domain data based on a subset of signs transmitted from the encoder as side-information. Frequency-domain data for a frame of an audio signal includes tonal components and noise components. Signs estimated from a random signal may be substantially accurate for the noise components of the frequency-domain data.Type: ApplicationFiled: May 10, 2006Publication date: April 26, 2007Inventors: Sang-Uk Ryu, Eddie Choy, Samir Gupta
