    摘要： A sound masking device includes: a sound pick-up unit which picks up a sound, and which produces a picked-up sound signal based on the sound, a masking sound signal producing unit which produces a masking sound signal from the picked-up sound signal a sound emitting unit which emits a masking sound based on the masking sound signal, and an echo cancelling unit which performs an echo cancelling process on the picked-up sound signal by performing an adaptive filtering process on the masking sound signal, and by subtracting the filtered masking sound signal from the picked-up sound signal. The masking sound signal producing unit produces a masking sound signal having a level corresponding to an amplitude level of the picked-up sound signal which has subjected to the echo cancelling process.

    摘要： A recording/reproducing apparatus includes a plurality of unidirectional microphones and a plurality of direction indicator switches. The unidirectional microphones are each disposed in the periphery with a predetermined angle interval therebetween, whereas the direction indicator switches are able to indicate other directions other than a plurality of directions corresponding to the unidirectional microphones. In a normal reproducing mode, a plurality of audio signals which are picked up by the unidirectional microphones and subsequently recorded is read and reproduced in parallel. When any one of the direction indicator switches is operated, only the audio signal emitted in the designated direction is selectively read and reproduced. When another direction other than a plurality of directions corresponding to the unidirectional microphones is designated, audio signals picked up by two unidirectional microphones which are disposed to sandwich the designated direction is selectively read and reproduced.

    摘要： Performance interface system includes a motion detector provided for movement with a performer, and a control system for receiving detection data transmitted from the motion detector and controlling a performance of a tone in response to the received detection data. State of a performer's motion is detected via a sensor of the motion detector, and detection data representative of the detected motion state is transmitted to the control system. The control system receives the detection data from the motion detector, analyzes the performer's motion on the basis of the detection data, and then controls a tone performance in accordance with the analyzed data. With this arrangement, the performer can readily take part in the tone performance in the control system. For example, as the performer moves his or her hand, leg or trunk while listening to a manual or automatic performance of a music piece being carried out by a performance apparatus of the control system, the motion detector detects the performer's motion and transmits corresponding detection data to the control system, which in turn variably controls a predetermined one of tonal factors in the music piece performance. This arrangement can readily provide interactive performance control and thereby allows an inexperienced or unskilled performer to take part in a performance with enjoyment.
