摘要： Aspects of the invention provide methods, computer-readable media, and apparatuses for spatially manipulating sound that is played back to a listener over a set of output transducers, e.g., headphones. The listener can direct spatial attention to focus on a portion of an audio scene, analogous to a magnifying glass being used to pick out details in a picture. An input multi-channel audio signal that is generated by audio sources is obtained, and directional information is determined for each of the audio sources. The user provides a desired direction of spatial attention so that audio processing can focus on the desired direction and render a corresponding multi-channel audio signal to the user. A region of an audio scene is expanded around the desired direction while the audio scene is compressed in another portion of the audio scene.

摘要： A mobile communication terminal allows a user to receive broadcast programming. A separate recording unit, which can be remote from the communication terminal, records that programming. One or more signals from the mobile terminal identify the broadcast frequency to which the mobile terminal is tuned and cause the recording unit to tune to the identified broadcast frequency. The signals from the mobile terminal also cause the recording unit to record at least a portion of a program being broadcast on the frequency to which the mobile terminal is tuned. The recording unit may buffer portions of broadcast programming being received on the identified frequency. A portion of the buffer contents can subsequently be transmitted to the mobile terminal, permitting the terminal user to replay the portion and identify a start point for the broadcast program. A signal from the mobile terminal can also cause the recording unit to automatically identify the start point in the buffer contents. After the start point is identified by the user or automatically by the recording unit, the recording unit is able to record substantially an entire broadcast program that is identified by the user after the program begins.

摘要： This invention describes a method for adjusting the loudness and the spectral content of digital audio signals in a real-time using warped spectral filtering. A warped processing module modifies a spectral content of a digital audio signal with a set of gains for a plurality of non-linearly-scaled frequency bands determined by a warping factor λ of a warped delay line. Warped delay line signals, generated by the warped delay line, are processed by a warped filter block containing multiple warped finite impulse response filters, e.g., Mth band filters, using individual warped spectral filtering in said plurality of the non-linearly-scaled frequency bands, which is followed by a conventional processing by a dynamic range control/equalization block. The present invention describes another innovation, that is embedding the warped processing module in a two-channel quadrature mirror filter (QMF) bank for improving processing efficiency at high sample rates.

摘要： Aspects of the invention provide methods, computer-readable media, and apparatuses for digital processing of acoustic signals to create a reproduction of a natural or an artificial spatial sound environment. An aspect of the invention supports spatial audio processing such as extracting a center channel in up-mixing stereo sound for multi-channel loudspeaker setup or headphone virtualization. An aspect of the invention also supports directional listening in which sound sources in a desired direction may be amplified or attenuated. Direction and diffuseness parameters for regions of input channels are determined and an extracted channel is extracted from the input channels according to the direction and diffuseness parameters. A gain estimate is estimated for each signal component being fed into the extracted channel and an extracted channel may be synthesized from a base signal and the gain estimate. The input channels may be partitioned into a plurality of time-frequency regions.

摘要： A stereo widening processing algorithm is used to provide a system and method for giving a listener an impression that a stereo audio signal having left and right channels is emanating from a virtual source spaced away from left and right stereo loudspeakers. This algorithm, which works particularly well when the loudspeakers are spaced apart by a distance that is less than optimal, introduces and filters cross-talk from the left channel to the right loudspeaker and cross-talk from the right channel to the left loudspeaker to only introduce cross-talk at frequencies below approximately 2 kHz, and primarily between 500 Hz to 1.5 kHz. The desired stereo widening is thereby achieved without noticeably affecting the sound quality of the stereo audio signal when played on the loudspeakers.
摘要翻译：使用立体声加宽处理算法来提供一种系统和方法，用于向聆听者提供具有左右声道的立体声音频信号从与左右立体声扬声器间隔开的虚拟源发出的印象。这种算法在扬声器间隔距离小于最优的情况下工作特别好，将从左声道到右扬声器的串扰和从右声道到左扬声器的串扰引入和滤除在低于约2 kHz的频率下，主要在500 Hz至1.5 kHz之间引入串扰。从而在扬声器上播放时不会明显影响立体声音频信号的声音质量，从而实现所需的立体声加宽。
