摘要： Systems, devices, and methods are described for recognizing and focusing on at least one source of an audio communication as part of a communication including a video image and an audio communication derived from two or more microphones when a relative position between the microphones is known. In certain embodiments, linked audio and video focus areas providing location information for one or more sound sources may each be associated with different user inputs, and an input to adjust a focus in either the audio or video domain may automatically adjust the focus in the another domain.

摘要： A microphone arrangement with improved directional characteristics is provided with at least two microphones (100, 102) and a signal processing arrangement (105). The signal processing arrangement is provided with a first (108) and a second input (109) for receiving the microphone signals of the at least two microphones. The inputs (108,109) are coupled to signal inputs of a first (110) and a second (111) multiplication circuit. The multiplication circuits are provided with control inputs for receiving respective first and second control signals, and with signal outputs. A control signal generator (112) is provided for generating the first and second control signals for the multiplication circuits (110,111). An arrangement (114) for a power corrected summation is provided, having a first and a second input coupled to the outputs of the first and second multiplication circuit, respectively, and having an output. A signal combination circuit (116) is provided with a first input (117) coupled to the output of the power corrected summation arrangement (114), a second input (118) coupled to one of the at least two microphones (102), and an output (119) coupled to the output (120) of the combination circuit (116). The first multiplication circuit (110) is adapted to multiply the signal applied to its input by a multiplication factor A*(1−g)1/2, under the influence of the first control signal. The second multiplication circuit (111) is adapted to multiply the signal applied to its input by a multiplication factor B*g1/2 under the influence of the second control signal. The multiplication factor g is frequency dependent (g[f]), and A and B are constant values, whose absolute values are preferably equal to 1. Further, A=B or A=−B applies. Preferably, the multiplication factor g[f], below a first frequency value, has a smaller value for increasing frequencies. Below a second frequency value that is smaller than the first frequency value, g[f] is a constant value (V), preferably equal to zero. (FIG. 2a) Thereby, a microphone arrangement can be obtained which exhibits a desired directional characteristics over an increased frequency range.

摘要： A remote speaker microphone having a directional microphone, a speaker, and a housing. The housing has a first portion sized to contain the speaker and a second portion sized to contain the directional microphone. The second portion defines a front port positioned adjacent the front surface of the directional microphone and a rear port positioned adjacent the rear surface of the directional microphone. The housing is configured to minimize the distance that sound waves travel within the housing before impacting on the sound receiving surfaces of the microphone.

摘要： In one embodiment, a directional microphone array having (at least) two microphones generates forward and backward cardioid signals from two (e.g., omnidirectional) microphone signals. An adaptation factor is applied to the backward cardioid signal, and the resulting adjusted backward cardioid signal is subtracted from the forward cardioid signal to generate a (first-order) output audio signal corresponding to a beampattern having no nulls for negative values of the adaptation factor. After low-pass filtering, spatial noise suppression can be applied to the output audio signal. Microphone arrays having one (or more) additional microphones can be designed to generate second- (or higher-) order output audio signals.
