摘要： In general, techniques are described for forming a collaborative sound system. A headend device comprising one or more processors may perform the techniques. 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： 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： A mobile audio device (for example, a cellular telephone, personal digital audio player, or MP3 player) performs Audio Dynamic Range Control (ADRC) (125) and Automatic Volume Control (AVC) (126) to increase the volume of sound (127) emitted from a speaker of' the mobile audio device so that faint passages of the audio will be more audible. This amplification of faint passages occurs without overly amplifying other louder passages, and without substantial distortion due to clipping. Multi-Microphone Active Noise Cancellation (MMANC) (133) functionality is, for example, used to remove background noise from audio information picked up on microphones of the mobile audio device. The noise-canceled audio may then be communicated from the device. The MMANC functionality generates a noise reference signal as an intermediate signal. The intermediate signal is conditioned and then used as a reference by the AVC process. The gain applied during the AVC process is a function of the noise reference signal.
摘要翻译：移动音频设备（例如，蜂窝电话，个人数字音频播放器或MP3播放器）执行音频动态范围控制（ADRC）（125）和自动音量控制（AVC）（126）以增加声音音量（127 ）从“移动音频设备”的扬声器发出，使得音频的微弱通道更可听见。这种微弱通道的放大发生，而不会过度放大其他更大的通道，并且没有由于限幅导致的实质性变形。例如，多麦克风有源噪声消除（MMANC）（133）功能用于从移动音频设备的麦克风拾取的音频信息中去除背景噪声。然后可以从设备传送噪声消除的音频。 MMANC功能产生噪声参考信号作为中间信号。中间信号被调节，然后用作AVC处理的参考。在AVC过程中应用的增益是噪声参考信号的函数。

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.
