摘要： A digital filter is composed of an FIR filter with a finite tap length and a feedback section. An apparatus for reproducing sound is arranged to use the digital filter. In the feedback section, an output of one of a plurality of delaying units included in the FIR filter is attenuated through the effect of a coefficient multiplier. The attenuated output is fed back to an adder located between adjacent delaying units arranged before the one delaying unit. The feedback section repeats the feedback operation to generate an infinitely continuing impulse response.

摘要： Audio reproducing apparatus reproducing an audio signal corresponding to a picture which localizes a sound image in a direction corresponding to the picture by processing an audio signal in a real-time fashion is supplied with an audio signal from a general-purpose signal source such as a laser disc a digital vibratory gyroscope detects a rotational angle of a listener's head. In response to the detected rotational angle, the audio reproducing apparatus subjects the audio signal to a predetermined signal processing in a real-time fashion. Thus, a sound image is localized in the direction corresponding to the picture projected on a screen from a projector.

The left channel and right channel acoustic signals are provided by a device for processing the transmission characteristics with constant transmission characteristics representing the location of an imaginary sound source relative to both of the listener's ears. The left channel and right channel acoustic signals, processed in this manner by the device for processing the transmission characteristics, are provided by an acoustic signal processing device with a level difference and a time difference consistent with changes in orientation of the user's head. In this manner, optimum binaural reproduction with respect to the imaginary sound source may be achieved.

摘要： A vibration type gyroscope apparatus of digital type which is good in operability and high in detection accuracy includes a variable gain amplifier (3), for amplifying a detection signal of a vibration type gyroscope, and an analog to digital converter (5), for converting an output signal of the variable gain amplifier (3) into a digital signal, are integratedly contained in the vibration type gyroscope apparatus. Accordingly, the detection signal is amplified and converted into a digital signal at a range as near as possible to a vibration type gyroscope (1) to thereby prevent the detection signal from being deteriorated by the influence of external noise in a transmission line. Accordingly, the transmission line can be used effectively, so that the signal can be transmitted at high-grade and high-fidelity.

摘要： A sound collecting system and a sound reproducing apparatus by means of which an actual audio image can be reproduced. The sound collecting system includes a plurality of microphones for producing sound signals and a plurality of position detecting apparatus for detecting locations of the microphones and/or positions of sound sources to produce position signals. The sound signals and the position signals are multiplexed by a plurality of multiplexers, and the multiplexed signals are stored into respective audio channels or different channels by a signal recording apparatus. The multiplexing may be performed by a frequency multiplexing method, a time division multiplexing method or the like. Since also position information is stored into corresponding audio channels together with acoustic sound signals, at the reproducing stage, reproduction is possible taking the positions into consideration and an actual audio image can be produced. Also dimensions, directivities and so forth of the sound sources can be multiplexed in addition to the position information.

摘要： In the audio signal reproducing apparatus, information on the transfer characteristics representative of the transfer characteristics from virtual sound sources to both ears of a listener in at least a first quadrant of the rotational angular position of the head M of the listener is stored in storing unit 22. The transfer characteristics in rotational angular position of the head M represented by detection outputs from detecting unit 5L, 5R and 13 for detecting the rotational angle position depending upon the movement of the head of the listener are formed based upon the transfer characteristics information of at least the first quadrant stored in the storing unit and left and right channel audio signals are processed by audio signal processing unit 23 for achieving a proper binaural reproduction relative to the virtual sound sources. Also in the audio signal processing apparatus of the present invention, information on the transfer characteristics from virtual sound sources to both ears of a listener for each given rotational angle depending upon the movement of the head M of the listener is stored in storing unit 62. The rotational angular position of the head of the listener is detected by detecting unit 45L, 45R and 53 at a solution higher than that of the information of the transfer characteristics stored in said storing unit. The information on at least two transfer characteristics in the vicinity of the rotational angular position represented by the detection outputs from detecting unit is read from the storing unit. The information on the transfer characteristics in the rotational angular position of the head represented by the detection output is interpolation operated by interpolation operating unit 61. Based upon the information on the transfer characteristics determined by the interpolation operation unit, left and right channel audio signals are processed by audio signal processing unit 63 for achieving a proper binaural reproduction relative to the virtual sound sources.
