Abstract: An apparatus for recording/reproducing information includes an externally-inputted information recording device and a reproducing device. An information amount checking device checks an amount of information of record information and/or information as recorded, when recording one of them on a recording medium. A recording capacity checking device checks a recording capacity of the recording medium on which the information is to be recorded. A judging device judges based on the checked information amount and recording capacity, as whether or not the whole of the information can be recorded on the recording medium. A dividing device divides the information into partial record informations each having an amount of information is equal to or smaller than the recording capacity. A partial information recording device repeats record of the partial record informations on the recording medium to record them thereon.

Abstract: First and second processing circuits are provided for carrying out a reverberation process of an input signal, and first and second filters are provided for applying amplitude characteristics to output signals of the first and second processing circuits. A first adder is provided for adding an output signal of the first processing circuit with an output signal of the second filter at opposed phase, and a second adder is provided for adding an output signal of the first filter with an output signal of second processing circuit in-phase. First and second speakers are provided to receive output signals of the first and second adders. The first and second amplitude characteristics are determined in accordance with a correlation coefficient of sound pressures of sounds from the first and second speakers.

Abstract: A sound field compensating apparatus is provided in which delay data produced by one of the delay means in a FIR filter, which is realized by the action of a DSP, is commonly used for producing a plurality of reflected sound data of corresponding channels. Accordingly, the maximum delay time of the delay data is lengthened without increasing the number of delay data retrieving actions per sampling period on the delay memory. Hence, an acceptable number of the reflected sound signals can be obtained for each channel.
