Abstract: An audio apparatus comprises a tuner for receiving broadcast waves; a digital reproducing unit; operation switches for operating the tuner and the digital reproducing unit; and a control unit for controlling the tuner and the digital reproducing unit in response to an operation of the operation means. In a first mode of operation, the control unit controls if an audio signal from the tuner is selected as a source such that the power of the digital reproducing unit is turned on, and wherein, in a second mode operation, the control unit controls if an audio signal from the tuner is selected as a source such that the power of the digital reproducing unit is turned off, alternatively if an audio signal from the digital reproducing unit is selected as a source, the power thereof is turned on.

Abstract: In a reproducing apparatus of the present invention, an input audio signal is divided into bands and an envelope value of each band is measured. Based on a change of the envelope value, a predetermined sound source is superimposed. Further, according to the envelope value of a reproduced audio signal, a tempo of reproduced music is detected and animation representation is changed in synchronism with the detected tempo. Further, a rhythm box is reproduced in synchronism with the detected tempo and a sound field is automatically selected corresponding to the detected tempo to perform synthesization.

Abstract: An optical disc reproducing apparatus can play multiple types of discs. The apparatus biases a focusing error signal based on the disc type. An analyzer receives reflected light of a light beam irradiated from an optical pick-up to a disc. A focus error signal is generated based on the signal supplied the analyzer. A switch selectively provides one of first and second bias voltages. A control controls which of the first and second bias voltages the switch provides based on the type of disc. The bias voltage is added to the focus error signal. An object lens of the optical pickup is driven based on the focus error signal with the bias voltage added.
