Abstract: A purpose of the invention is to provide a noise gate that can output an audio signal in which only a stationary noise is removed, without degrading an utterance voice of a speaking person. A sound collection device 1 includes an FFT processing unit 11, the noise gate 12, and an IFFT processing unit 13.The sound collection device 1 transforms a collected audio signal NET into a frequency spectrum NE′N by using the FFT processing unit 11. The noise gate 12 estimates a noise spectrum N′N of a stationary noise based on the frequency spectrum NE′N of the audio signal. The noise gate 12 decreases a signal level (a gain) of the audio signal in a case where a signal level ratio of the frequency spectrum NE′N of the audio signal to the noise spectrum N′N is less than a threshold value, and outputs the audio signal. The sound collection device 1 outputs an audio signal CO′T which is generated in such a manner that the IFFT processing unit 13 inversely transforms a frequency spectrum CO′N after removing the stationary noise N′N.

Abstract: Provided is a sound emission and collection device capable of estimating the azimuth of a sound source (such as a main utterer) precisely without any processing load. The sound emission and collection device (1) is connected with another sound emission and collection device via a network or the like. The sound emission and collection device (1) receives a sound signal from another sound emission and collection device, as a sound emission signal (FE), and emits the same from a speaker (SP). The sound emission and collection device (1) collects the sound at microphones (MIC1 to MIC3), and produces sound collection beam signals (NE1 to NE3) of different azimuths. The sound emission and collection device down-samples the individual sound collection beam signals (NE1 to NE3), and filters out the echoes of the down-sampled sound collection beam signals (DNE1 to DNE3). The sound emission and collection device selects the sound collection beam signal (DNE1′) of the highest signal level from the echo-filtered sound collection beam signals (DNE1′ to DNE3′). The sound emission and collection device filters out the echoes of a sound collection beam signal (NE1) from the sound collection azimuth (D1) of the sound collection beam signal (DNE1′), and transmits the same to another sound emission and collection device.

Abstract: A position detecting system is provided, which is capable of effectively preventing erroneous detection of audio to be measured. The position detecting system includes a terminal device that inputs an audio signal from an audio device and a microphone. The audio device sequentially inputs measurement audio signals that have been formed by two or more audio signals of different frequencies to a speaker and receives a notification signal, wherein the report signal indicates that the audio of the measurement audio signal has been collected from the terminal device. The audio device clocks a time t1 and a time t2, namely clocks after the audio of the measurement audio signal is output from the speakers SP1-SP2 until the notification signals of the measurement audio signals are received by the signal receiving unit. The audio device calculates the position of the microphone by using the times t1 and t2. For each frequency component of the measurement audio signal, when an audio signal exceeding a predetermined level is inputted from the microphone, the terminal device detects it as a component of the measurement audio signal and transmits a notification signal upon detection of the measurement audio signal.

Abstract: To provide an audio conference apparatus and an audio conference system which can smoothly proceed with the audio conference by removing a recursion sound of the conference voice is achieved. An audio conference apparatus 1 outputs ring tones from corresponding channels before a communication control unit 12 outputs audio signals from the unused channels (S1 to S3).

Abstract: A control unit gives acoustic environment instruction data to a picked up sound directionality control unit and an adaptive filter. According to this, the picked up sound directionality control unit generates a picked up sound signal constituted by a predetermined picked up sound directionality. The adaptive filter detects the picked up sound directionality from the acoustic environment instruction data, and reads out the filter parameter corresponding to this picked up sound directionality, from a memory. The adaptive filter sets a delay coefficient and a filter coefficient of an FIR filter, and generates a pseudo echo signal by an impulse response with respect to the received sound signal. Based on an error signal obtained by subtracting the pseudo echo signal from the picked up sound signal by an adder, the adaptive filter sets a more optimum filter parameter, and generates the next pseudo echo signal.
