Abstract: The present disclosure relates to reverberation generation for headphone virtualization. A method of generating one or more components of a binaural room impulse response (BRIR) for headphone virtualization is described. In the method, directionally-controlled reflections are generated, wherein directionally-controlled reflections impart a desired perceptual cue to an audio input signal corresponding to a sound source location. Then at least the generated reflections are combined to obtain the one or more components of the BRIR. Corresponding system and computer program products are described as well.

Abstract: In some embodiments, a method for monitoring speakers within an audio playback system (e.g., movie theater) environment. In typical embodiments, the monitoring method assumes that initial characteristics of the speakers (e.g., a room response for each of the speakers) have been determined at an initial time, and relies on one or more microphones positioned in the environment to perform a status check on each of the speakers to identify whether a change to at least one characteristic of any of the speakers has occurred since the initial time. In other embodiments, the method processes data indicative of output of a microphone to monitor audience reaction to an audiovisual program. Other aspects include a system configured (e.g., programmed) to perform any embodiment of the inventive method, and a computer readable medium (e.g., a disc) which stores code for implementing any embodiment of the inventive method.
Abstract translation: 在一些实施例中，一种用于监视音频播放系统（例如，电影院）环境中的扬声器的方法。 在典型的实施例中，监视方法假设扬声器的初始特性（例如，每个扬声器的房间响应）已经在初始时间被确定，并且依赖于位于环境中的一个或多个麦克风来执行状态检查 在每个扬声器上，以识别自从初始时间以来是否发生了任何扬声器的至少一个特征的改变。 在其他实施例中，该方法处理指示麦克风的输出的数据，以监视对视听程序的观众反应。 其他方面包括配置（例如，编程）以执行本发明方法的任何实施例的系统，以及存储用于实现本发明方法的任何实施例的代码的计算机可读介质（例如，盘）。

Abstract: Some headphone systems include two ear cups, a headband assembly, an interface system and a control system. Each ear cup may include an ear cup enclosure, an ear pad assembly, a speaker system and a hinge assembly. The hinge assembly may be disposed within the ear cup enclosure such that it is not visible from outside the ear cup. The headband assembly may connect with each of the ear cups via the hinge assembly. The interface system may include at least one interface and a plurality of input source buttons disposed on at least one of the ear cups. Each of the input source buttons may be configured for selecting a source of audio data received via the at least one interface. The control system may be configured for controlling the speaker system to reproduce audio data received via the interface and selected by one of the input source buttons.
