摘要： A computing device generates an audio signal that includes a pattern and transmits the audio signal to the loudspeakers. A measuring device located at a listening position sequentially captures the signal and pattern reproduced by the speakers. The measuring device transmits each captured signal and pattern to the computing device. The computing device determines the frequency and impulse responses for each loudspeaker and equalizes the speakers for the listening position. Some or all of the speakers may be associated with additional listening positions. The computing device may then equalize the speakers based on each listening position. Alternatively, the computing device may calculate an average for some or all of the listening positions and equalize the speakers based on the average.

摘要： Improved approaches to flexibly implementing graphic equalizers on media players are disclosed. These approaches provide dynamic order reduction of a multi-band graphic equalizer so that equalizer effects can be timely performed with only limited computational resources. In one embodiment, a media player receives a media item and associated equalizer settings for a multi-band graphic equalizer. The media player can then automatically (i.e., without user action) approximate the multi-band graphic equalizer with the equalizer settings for the media item using a fewer number of filters. Fewer filters means order reduction, and thus reduction in computational requirements. After the multi-band graphic equalizer is approximated, the media player can present the media item to its user in accordance with the reduced complexity, approximated equalizer.

摘要： A technique for enhancing audio signals generated from compressed digital audio files is described. The technique uses a Bass Maximizer module, a Harmonic Exciter module and a Quasi Stereo module. The Bass Exciter module enhances the intensity, depth and punch of the bass audio content by creating harmonic sequences from low frequency components contained in the original input signal. The Harmonic Exciter module adds to the treble audio content of the original input signal by generating harmonic series from the high frequency components contained in the input signal. The Quasi Stereo Module creates a stereo image of the enhanced input signal by adding and subtracting delayed and filtered versions of the enhanced input signal with itself to create left and right channeled stereo-like outputs. The technique provides a useful tool to regenerate from an audio signal more pleasant and joyful sounds.
摘要翻译：描述了一种用于增强从压缩数字音频文件产生的音频信号的技术。该技术使用低音最大化模块，谐波激励器模块和准立体声模块。低音激励器模块通过创建包含在原始输入信号中的低频分量的谐波序列来增强低音音频内容的强度，深度和冲击。谐波激励器模块通过从包含在输入信号中的高频分量产生谐波序列来增加原始输入信号的高音音频内容。准立体声模块通过增加和减去增强输入信号的延迟和滤波版本自身来创建增强输入信号的立体声图像，以创建左右通道立体声输出。该技术提供了一种有用的工具，可以从音频信号中重现更加愉快和快乐的声音。

摘要： A method of detecting a user's voice activity in a headset with a microphone array is described herein. The method starts with a voice activity detector (VAD) generating a VAD output based on acoustic signals received from microphones included in a pair of earbuds and the microphone array included on a headset wire and data output by an accelerometer that is included in the pair of earbuds. A noise suppressor may then receive the acoustic signals from the microphone array and the VAD output and suppress the noise included in the acoustic signals received from the microphone array based on the VAD output. The method may also include steering one or more beamformers based on the VAD output. Other embodiments are also described.

摘要： Providing an alternative human interface for an electronic device when a current human interface is made ineffective by at least an environmental factor is described herein. By ineffective it is meant that the current human interface cannot maintain a minimum level of interactivity between a user and the electronic device in the current or anticipated environment. In addition to maintaining at least a threshold level of interactivity, the configuration of the alternative human interface can take into consideration other factors such as an expected operating state of the electronic device affected by the choice of alternative human interface.
