摘要： A wireless device is provided that makes use of other nearby audio transducer devices to generate a surround sound effect for a targeted user. To do this, the wireless device first ascertains whether there are any nearby external microphones and/or loudspeaker devices. An internal microphone for the wireless device and any other nearby external microphones may be used to ascertain a location of the desired/targeted user as well as the nearby loudspeaker devices. This information is then used to generate a surround sound effect for the desired/targeted user by having the wireless device steer audio signals to its internal loudspeakers and/or the nearby external loudspeaker devices.

摘要： A vehicle having means for determining a position and means for storing information including an audio icon associated with one or more landmarks. Means are provided for retrieving the audio icon based on the position, for rendering an audio signal based on the audio icon into a three-dimensional audio space within the vehicle and for outputting a spatial auditory sound into the three-dimensional audio space based on the audio signal, the spatial auditory sound enabling perception of the landmark location relative to a location within the vehicle.
摘要翻译：导航系统产生在三维空间中感知的音频提示，允许用户在听觉上感知诸如地标之类的映射对象的位置。音频提示可以单独制作，也可以在某些应用程序中与视觉导航地图显示一起制作，以提高系统的整体效能。音频导航系统包括用于确定用户位置的定位系统，用于存储关于一个或多个对象的分层组织信息的存储器以及用于基于分层组织信息呈现音频信号的处理器。音频信号被渲染到对应于用户的音频空间中，以便允许用户感知至少一个对象相对于用户的位置的位置。对象可以是用户附近的地标。

摘要： Mid-side (M-S) encoded audio is reproduced by a device that includes a multi-channel digital-to-analog converter (DAC). The DAC has a first channel input receiving a digitized mid audio signal, a first channel output providing an analog mid audio signal, a second channel input receiving a digitized side audio signal and a second channel output providing an analog side audio signal. The DAC may also include a third channel for receiving a digitized second side audio signal. The second side audio signal is phase inverted. The device may be a handheld wireless communication device, such as a cellular phone, and may also include transducers for outputting M-S encoded sound in response to the analog mid and side audio signals.
摘要翻译：中端（M-S）编码音频由包括多通道数/模转换器（DAC）的装置再现。 DAC具有接收数字化中音频信号的第一声道输入，提供模拟中音频信号的第一声道输出，接收数字化侧音频信号的第二声道输入和提供模拟侧音频信号的第二声道输出。 DAC还可以包括用于接收数字化的第二侧音频信号的第三通道。第二侧音频信号是相位反相的。该设备可以是诸如蜂窝电话的手持无线通信设备，并且还可以包括用于响应于模拟中间和侧面音频信号而输出M-S编码声音的换能器。

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.
摘要翻译：本公开描述了将两个或多个音频信号智能地组合成输出信号的音频混合技术。这些技术允许音频被组合，但是在不同音频信号之间产生感知差异。结果是用户能够听到组合输出中的两个音频信号，但是不同的音频信号不会感知到彼此干扰。这些技术实现起来相对简单，并且非常适合于无线电话。
