摘要： Spatial auditory cues are produced while a user searches a database for stored information. The spatial auditory cues assist the user in quickly locating stored information by producing sounds that are perceived at specific physical locations in space around the user as the search proceeds. Each location may be associated with different information. Thus, using the techniques disclosed herein, a user can more easily recall stored information by remembering the locations of sound produced by particular spatial auditory cues. The spatial auditory cues may be used in conjunction with a visual search interface. A method of producing auditory cues includes receiving a search action at a user interface included in a device, translating the search action into a spatial auditory cue corresponding to a specific location within a space, and rendering the spatial auditory cue as an audio output signal.

摘要： 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.
摘要翻译：维持音频信号的原始响度级别，同时保持声音质量尽可能好并且保护移动设备中使用的扬声器。音频（例如，语音）信号的响度可以在控制扬声器（在移动设备中）的振膜的偏移保持在允许的范围内的同时被最大化。在实现中，使用输入信号和偏移传递函数预测（例如，估计）峰值偏移。然后可以修改信号以限制偏移并且最大化响度。

摘要： In accordance with a method for providing a distinct perceptual location for an audio source within an audio mixture, a foreground signal may be processed to provide a foreground perceptual angle for the foreground signal. The foreground signal may also be processed to provide a desired attenuation level for the foreground signal. A background signal may be processed to provide a background perceptual angle for the background signal. The background signal may also be processed to provide a desired attenuation level for the background signal. The foreground signal and the background signal may be combined into an output audio source.

摘要： A technique for canceling acoustic crosstalk is provided including a pre-processing filter and a crosstalk cancellation device. The pre-processing filter may be configured to obtain first and second channel signals and compensate or adjust the first and/or second channel signals for anticipated subsequent stage distortion by the crosstalk cancellation device. The crosstalk cancellation device maybe configured to receive the compensated first and second channel signals from the pre-processing filter. The crosstalk cancellation device then modifies the first channel signal to cancel anticipated acoustic crosstalk from the second channel signal, and modifies the second channel signal to cancel acoustic crosstalk from the first channel signal. The modified first channel signal is then transmitted over a first speaker and the modified second channel signal is transmitted over a second speaker. The first and second speakers may be closely spaced, yet provide a widened stereo image of the first and second channel signals.

摘要： This disclosure describes audio mixing techniques that intelligently combine two or more audio signals into an output signal. The techniques allow audio to be combined, yet create perceptual differentiation between the different audio signals. The result is that a user is able to hear both audio signals in a combined output, but the different audio signals do not perceptually interfere with one another. The techniques are relatively simple to implement and are well suited for radio telephones.

The processors may be configured to identify mobile devices that each includes a speaker and that are available to participate in a collaborative surround sound system. The processors may configure the collaborative surround sound system to utilize the speaker of each of the mobile devices as one or more virtual speakers of this system and then render audio signals from an audio source such that when the audio signals are played by the speakers of the mobile devices the audio playback of the audio signals appears to originate from the one or more virtual speakers of the collaborative surround sound system. The processors may then transmit the processed audio signals rendered to the mobile device participating in the collaborative surround sound system.

摘要： Some implementations provide a method for identifying a speaker. The method determines position and orientation of a second device based on data from a first device that is for capturing the position and orientation of the second device. The second device includes several microphones for capturing sound. The second device has movable position and movable orientation. The method assigns an object as a representation of a known user. The object has a moveable position. The method receives a position of the object. The position of the object corresponds to a position of the known user. The method processes the captured sound to identify a sound originating from the direction of the object. The direction of the object is relative to the position and the orientation of the second device. The method identifies the sound originating from the direction of the object as belonging to the known user.

摘要： Methods and apparatuses for providing tangible control of sound are provided and described as embodied in a system that includes a sound transducer array along with a touch surface-enabled display table. The array may include a group of transducers (multiple speakers and/or microphones) configured to perform spatial processing of signals for the group of transducers so that sound rendering (in configurations where the array includes multiple speakers), or sound pick-up (in configurations where the array includes multiple microphones), have spatial patterns (or sound projection patterns) that are focused in certain directions while reducing disturbances from other directions. Users may directly adjust parameters related to sound projection patterns by interacting with the touch surface while receiving visual feedback by exercising one or more commands on the touch surface. The commands may be adjusted according to visual feedback received from the change of the display on the touch surface.
