摘要： An electrostatic transducer including a membrane, a first electrode and a second electrode. The first electrode is disposed parallel to the membrane. The membrane is configured to respond mechanically to a varying first electric field in accordance with respective electric potentials applied between the first electrode and the membrane. The second electrode is disposed parallel to the membrane opposite from the first electrode. The membrane is configured to respond mechanically to a varying second electric field in accordance with respective electric potentials between the second electrode and the membrane. The first and second electrodes have through holes configured for acoustic transmission to and from the membrane. The housing includes: (i) a nozzle configured for acoustic transmission from the membrane through the holes of the first electrode to an ear canal and (ii) an aperture configured to provide acoustic transmission through the holes of the second electrode between the membrane and air external to the housing.

摘要： Adjusting gains of an audio mix. Audio tracks using respective gains are individually analyzed to compute a first metric of frequency content. A user input specifies a desired second metric of the frequency content. Responsive to the user input, respective gains of the audio tracks are collectively and simultaneously adjusted to produce respective adjusted gains of the audio tracks. A second audio mix when played of the audio tracks with the respective adjusted gains has a third metric of frequency content different from the first metric of frequency content. The third metric is closer to the second metric than said first metric.

摘要： An audio system including a first microphone-equipped playback device and a second microphone-equipped playback device. The audio system is configured to synchronize playing of audio to a listener position by receiving by the first microphone-equipped playback device an audio stream, and playing the audio stream on a speaker of the first microphone-equipped playback device, in accordance with a playback delay Δt. The playback delay Δt is in accordance with a first calibration sound originating at the listening position, a second calibration sound originating at the second microphone-equipped playback device, and a third calibration sound originating at the first microphone-equipped playback device.

摘要： A trained machine configured to input a stereo sound track and separate the stereo sound track into multiple N separated stereo audio signals respectively characterized by multiple N audio content classes. All stereo audio as input in the stereo sound track is included in the N separated stereo audio signals. A mixing module is configured to spatially localize symmetrically and without cross-talk, between left and right, the N separated stereo audio signals into multiple output channels. The output channels include respective mixtures of one or more of the N separated stereo audio signals. Gain is adjusted of the output channels into left and right binaural outputs to conserve summed levels of the N separated stereo audio signals distributed over the output channels.

摘要： A method for conveying to a listener a directionality-preserving pseudo low frequency psycho-acoustic sensation of a multichannel sound signal, including: deriving from the sound signal, by a processing unit, a high frequency multichannel signal and a low frequency multichannel signal, generating a multichannel harmonic signal, the loudness of at least one channel signal of the multichannel harmonic signal substantially matching the loudness of a corresponding channel in the low frequency multichannel signal; and at least one interaural level difference (ILD) of at least one frequency of the at least one channel pair of the multichannel harmonic signal substantially matching an ILD of a corresponding fundamental frequency in a corresponding channel pair in the low frequency multichannel signal; and summing the harmonic multichannel signal and the high frequency multichannel signal thereby giving rise to a psychoacoustic alternative signal.

摘要： A circuit, method, and system for producing artificial ambience effect for an input audio signal, mono, stereo, or surround. The ambience effect enhances artificial reverberation, replaces artificial reverberation, or synthesizes extra audio channels, such as surround channels. The circuit may include a transient reduction module and a reverberation filter. The transient reduction module may be adapted to reduce transients in an input audio signal of one or more channels. The reverberation filter maybe adapted to receive a transient-reduced signal of one or more channels corresponding to the transient-reduced signal.

摘要： A method for processing audio signal that includes receiving a plurality of digital audio signals and calculating signal levels of them. The next step is calculating smooth attenuation signal for each one of the input audio signals. The smooth attenuation signals are calculated according to the signal levels and smoothing criteria, such that the mixing of signals that include the input audio signals multiplied by their respective smooth attenuation signals is peak limited by a given threshold level.
