Abstract: A column loudspeaker with a line of low-frequency drivers has a center coaxial driver with a low frequency driver and a high frequency drive. The low frequency drivers are delayed and gain adjusted such that they exhibit constant directivity in the axis of the line. The high frequency driver has the same directivity as the line of low frequency drivers. A crossover separates the audio signal into high and low frequency signals with low frequency signals sent to the low frequency drivers, and high frequency signals sent to the high frequency element in the coaxial driver. The crossover frequency is in the frequency range where the directivity of the high and low frequency drivers match. The loudspeaker cabinet is curved to provide an acoustic delay to the drivers further away from the center coaxial driver.

Abstract: A data transmission method, where a host acquires parameter information of a wireless communication channel between a wireless microphone array and the host, that is, a signal-to-noise ratio or bandwidth. The host reduces sampling frequency of the wireless microphone array or decreases a quantity of data transmission paths between the wireless microphone array and the host when the acquired parameter information satisfies a first preset condition such that bandwidth occupied when the wireless microphone array transmits data is reduced.

Abstract: A method and apparatus are disclosed to recreate directional cues and in a conventional beamformed monophonic audio signal. In an example embodiment, the apparatus captures sound in an environment via the microphone array which includes a left reference and a right reference microphone. A monophonic audio signal is generated using conventional beamforming methods. A conventional monophonic beamformed signal lacks directional cues which may be useful for multiple output channels. By applying the phase offset data of the audio signals at the left and right reference microphones, directional cues may be created for audio signals for the left and right output channels respectively.

Abstract: The present technology relates to a sound field collecting apparatus and method, a sound field reproducing apparatus and method and a program which enable a sound field to be reproduced accurately at lower cost. Each linear microphone array outputs a sound collection signal obtained by collecting a sound field. A spatial frequency analysis unit performs spatial frequency transform on each sound collection signal to calculate spatial frequency spectra. A space shift unit performs space shift on the spatial frequency spectra so that central coordinates of the linear microphone arrays become the same, to obtain spatially shifted spectra. A space domain signal mixing unit mixes a plurality of spatially shifted spectra to obtain a single microphone mixed signal. By mixing the sound collection signals of the plurality of linear microphone arrays in this manner, it is possible to reproduce a sound field accurately at low cost. The present technology can be applied to a sound field reproducer.

Abstract: System comprising a processing unit configured to compute transmit signals and an array of speakers in wired or wireless communication with the processing unit, each of the speakers of the array at different locations in a common setting. The speakers, upon receiving the transmit signals, simultaneously transmit both a first audio and a different second audio stream into the setting from the speakers. The first stream from the speakers aggregate in the vicinity of a first location in the setting to form an aggregated first stream that is audible to human hearing. The second stream transmitted from the speakers do not aggregate at the first location. The second stream from the speakers aggregate in the vicinity of a different second location in the setting to form an aggregated second stream that is audible to human hearing. The first stream transmitted from the speakers do not aggregate at the second location.
