An enhanced Stereo Dimensional Array (SDA) loudspeaker system 250 preferably including a mirror image pair of loudspeaker enclosures 280L, 280R configurable by a user or installer as a left-channel SDA loudspeaker and a right channel SDA loudspeaker uses a novel driver array aiming configuration and an enhanced Head Shadow filter SDA signal processing system and method to achieve a surprisingly effective psycho-acoustically expanded image breadth by inter-aural crosstalk cancellation. The signal processing system and method provide an enhanced method for cancellation of apparent sources of inter-aural crosstalk, as compared to the commonly owned Polk SDA (prior art) method.

The present disclosure is directed to multichannel transducer devices and methods of operation thereof. One example device includes at least two acquisition modules that have different sensitives and a signal processing stage that generates a blended signal representative of a lower gain signal mapped onto a higher gain signal. One example method of operation includes receiving a first signal from a first sensor having a first sensitivity, receiving a second signal from a second sensor having a second sensitivity that is different from the first sensitivity, generating a blended signal by mapping the second signal to the first signal, outputting the first signal while the first signal is below a first threshold and above a second threshold, and outputting the blended signal when the first signal is above the first threshold and when the first signal is below the second threshold.

A piece of audio equipment is provided that includes a first signal path including a first dynamic range expander and a lowpass filter. The piece of audio equipment also includes a second signal path parallel to the first signal path, wherein the second signal path includes a second dynamic range expander and a highpass filter. The piece of audio equipment further includes a summing amplifier configured to receive a first signal from the first signal path, a second signal from the second signal path, and a clear signal from an audio source and output a summed signal.

A signal processing device includes: a resonant band-pass filter which extracts frequency components which cause resonance of a housing from an input signal; a harmonic generating unit which generates a harmonic signal for an output signal of the resonant band-pass filter; an adding unit which adds an output signal of the harmonic generating unit and at least a portion of frequency components of the input signal; and a resonant band-stop filter which removes the frequency components which cause the resonance of the housing from an output signal of the adding unit.

The present technology relates to a signal processing device, a signal processing method, and a program for enabling reproduction of high-quality sounds with a low process load. The signal processing device includes a demultiplexing section that extracts encoded audio signals and overamplitude flags, which have been generated for a plurality of respective panel loudspeakers and each indicate whether overamplitude will occur in the corresponding panel loudspeaker, by demultiplexing encoded data, a decoding section that decodes the encoded audio signals, and an adjustment section that adjusts audio signals to be supplied to the plurality of panel loudspeakers on the basis of the overamplitude flags and audio signals resulting from the decoding. The present technology is applicable to an encoding device and a decoding device.

A method including: obtaining at least two audio signals for reproduction, each of the at least two audio signals associated with a respective one of at least two reproduction locations within an audio reproduction space; obtaining within the audio reproduction space at least two zones; obtaining at least one location for a user's position within the audio reproduction space, the at least one location being relative to at least one of the at least two zones and the at least two reproduction locations; and processing the at least two audio signals based on the obtained at least one location for the user's position within the audio reproduction space to generate at least one output audio signal, the at least one output audio signal is reproduced from at least one of the at least two reproduction locations.

A portable sound enhancement module for interconnection between a stereo signal source and a sound generator such as stereo headphones, includes an audio driver with a positive left input, a negative left input, a positive right input and a negative right input, the positive right input and the positive left input of the audio driver and the negative left signal and the negative right signal source are coupled to ground. The positive left signal is coupled to the negative left input and the positive right signal is coupled to the negative right input. The enhancement module includes a battery, a charger and a programmable controller. The controller sets the amplification level for the audio driver, indicates the state of the battery charge and turns the enhancement module on and off in response to predefined criteria. The sound generator is coupled to receive the right output signal and the left output signal from the enhancement module and generate enhanced sound in accordance with the invention.

The transparent conductive film includes on a transparent film base a transparent electrode layer in which a transparent conductive oxide layer and a patterned metal layer are stacked in contact with each other. The maximum layer thickness of the transparent electrode layer is 300 nm or less. The metal layer has a metal pattern width of 1 m or more and 8 m or less, and the metal pattern coverage ratio of 0.4% or more and 3.2% or less. It is preferable that the metal layer has a layer thickness of 50 nm or more and 250 nm or less. It is also preferable that the pattern shape of the metal layer is of stripes, mesh, dots or the like.

A system and method are described for transforming stereo signals into mid and side components xm and xs to apply processing to only the side-component xs and avoid processing the mid-component. By avoiding alteration to the mid-component .sub.XM, the system and method may reduce the effects of ill-conditioning, such as coloration that may be caused by processing a problematic mid-component xM while still performing crosstalk cancellation and/or generating virtual sound sources. Additional processing may be separately applied to the mid and side components x.sub.M and xs and/or particular frequency bands of the original stereo signals to further reduce ill-conditioning.

Audio processing method is described to continuously process an audio signal while changing between audio modes so that the listener does not experience a discontinuous sound during the transition. The first audio signal can be combined with the second audio signal to produce a smooth, continuous output signal that changes to only having the second audio signal over a time period. A global gain can be reduced during the transition from the first audio mode to a subsequent audio mode. Differences in the parameters from the first mode to the second mode can be determined and the parameters that differ are stepped from an initial value to a subsequent value over a transition time to produce a smooth audio signal.
