Publication number: 20230360660Abstract: Disclosed are methods and systems for decoding immersive audio content encoded by an adaptive number of scene elements for channels, audio objects, higher-order ambisonics (HOA), and/or other sound field representations. The decoded audio is rendered to the speaker configuration of a playback device. For bit streams that represent audio scenes with a different mixture of channels, objects, and/or HOA in consecutive frames, fade-in of the new frame and fade-out of the old frame may be performed. Crossfading between consecutive frames happen in the speaker layout after rendering, in the spatially decoded content type before rendering, or between the transport channels as the output of the baseline decoder but before spatial decoding and rendering. Crossfading may use an immediate fade-in and fade-out frame (IFFF) for the transition frame or may use an overlap-add synthesis technique such as time-domain aliasing cancellation (TDAC) of MDCT.Type: ApplicationFiled: September 10, 2021Publication date: November 9, 2023Inventors: Moo Young KIM, Dipanjan SEN, Eric ALLAMANCHE, J.

Patent number: 11563411Abstract: An audio normalization gain value is applied to an audio signal to produce a normalized signal. The normalized signal is processed to compute dynamic range control (DRC) gain values in accordance with a selected one of several pre-defined DRC characteristics. The audio signal is encoded, and the DRC gain values are provided as metadata associated with the encoded audio signal. Several other embodiments are also described and claimed.Type: GrantFiled: March 3, 2021Date of Patent: January 24, 2023Assignee: APPLE INC.Inventors: Frank Baumgarte, Eric A. Allamanche, Stefan K.

Publication number: 20220392460Abstract: Disclosed are systems and methods to modify the Bluetooth mono HFP protocol to support bi-directional stereo operation for high bandwidth audio including 12-KHz wide-band, 16-KHz super wide-band (SWB), and 24-KHz full band (FB) audio. The techniques leverage the larger packet size and longer duty cycle of the 2-EV5 transport packet and expand the block size of the audio frames generated by the AAC-ELD codec to increase the maximum data throughput from the 64 kbps of the mono HFP protocol to 192 kbps using a stereo HFP protocol. The increased throughput not only supports stereo operations, but allows the transport of redundant or FEC packets for increased robustness against packet loss. In one aspect, the AAC-ELD codec may be configured for dynamic bit rate switching to flexibly perform trade-offs between audio quality and robustness against packet loss. The stereo HFP may configure the maximum throughput based on the desired audio quality.Type: ApplicationFiled: May 11, 2022Publication date: December 8, 2022Inventors: Aarti Kumar, Eric A. Allamanche, Su Fu, Leijun Dong

Publication number: 20210392129Abstract: The embodiments set forth a technique for enabling a computing device to securely configure a peripheral computing device. According to some embodiments, the method can include the steps of (1) approving a request received from the peripheral computing device to engage in a setup procedure for the peripheral computing device, (2) receiving, from the peripheral computing device: (i) an audio signal that encodes a password and timing information, and (ii) a light signal. Additionally, the method can involve, in response to identifying that the timing information correlates with the light signal: (3) extracting the password from the audio signal, and (4) establishing a communication link with the peripheral computing device based on the password. In turn, the method can involve (5) providing configuration information to the peripheral computing device over the communication link.Type: ApplicationFiled: June 23, 2021Publication date: December 16, 2021Inventors: Jay S. COGGIN, Daniel C. KLINGLER, Kyle C. BROGLE, Johannes P. SCHMIDT, Eric A. ALLAMANCHE, Thomas ALSINA, Bob BRADLEY, Alex T. NELSON, Rudolph VAN DER MERWE, Joseph M.

Patent number: 10992276Abstract: An audio encoding device and an audio decoding device are described herein. The audio encoding device may examine a set of audio channels/channel groups representing a piece of sound program content and produce a set of ducking values to associate with one of the channels/channel groups. During playback of the piece of sound program content, the ducking values may be applied to all other channels/channel groups. Application of these ducking values may cause (1) the reduction in dynamic range of ducked channels/channel groups and/or (2) movement of channels/channel groups in the sound field. This ducking may improve intelligibility of audio in the non-ducked channel/channel group. For instance, a narration channel/channel group may be more clearly heard by listeners through the use of selective ducking of other channels/channel groups during playback.Type: GrantFiled: February 7, 2019Date of Patent: April 27, 2021Assignee: APPLE INC.Inventors: Tomlinson M.

Patent number: 10880379Abstract: Methods and apparatus to manage communication sessions to handover between a direct connection at a secondary wireless device and a relayed connection to the secondary wireless device via a primary wireless device. A connection manager of a secondary wireless device can trigger transfer of a communication session based on measurements of performance metrics for the communication session. Upon detection of performance degradation in a local connection or a backhaul connection or both, the connection manager of the secondary wireless device can determine proximity of and/or capabilities for connections of the primary wireless device and instigate transfer of the communication session between different connection types, such as between a direct connection and a relayed connection. The transfer of the communication session can occur without user intervention or in response to input from the user without interrupting or reestablishing the communication session.Type: GrantFiled: November 26, 2018Date of Patent: December 29, 2020Assignee: Apple Inc.Inventors: Luciano M.
