Abstract: An information playback apparatus is provided to obtain editing effects using an optical disc in the same sense as an analog record disc is manipulated. An audio editing apparatus for playing back an optical disc such as a CD is provided with a rotatable jog dial, detecting device for detecting the amount of rotation of the jog dial, and sensing device for sensing the presence or absence of a pressing force on the jog dial. When the jog dial is rotated while being depressed with a predetermined pressing force, processing for providing sound effects is performed on the playback data to be played back from the optical disc in response to the amount of rotation detected by the detecting device. It is thereby possible to provide the same feeling of operation as provided by rotating an analog record disc through hand operations to produce playback sounds.

Abstract: An audio signal mixer capable of performing a long mix editing with simple manipulations. A second audio signal producing means is prevented from producing a second audio signal when an operating member is positioned at a first end, while a first audio signal producing means is prevented from producing a first audio signal when the operating member is positioned at a second end. As the operating member is moved away from the first end or the second end, the first and second audio signals are mixed. As the operating member is moved toward the second end, the level of the first audio signal is gradually decreased while the level of the second audio signal is gradually increased. Conversely, as the operating member is moved toward the first end, the level of the second audio signal is gradually decreased while the level of the first audio signal is gradually increased.

Abstract: A signal adjusting apparatus includes a movable member, a setting device, and a prohibiting device. The movable member is movable in a movable range to have the electrical signal adjusted in accordance with a position of the movable member. The setting device sets a prohibition range in the movable range. The prohibition range is a range where a volume level of the electrical signal is to be constant. The prohibiting device prohibits the volume level from being adjusted under the state that the movable member is located in the prohibition range.

Abstract: A signal adjusting apparatus comprises a movable member, a first detecting device, a second detecting device, and a correction device. The member is movable in a movable range composed of a plurality of intervals. The first detecting device detects one of the intervals where the member is located. The first detecting device is constituted by a first movable portion mounted on the member and a first fixed portion spaced apart from the first movable portion. The one of the intervals is an absolute position. The second detecting device detects a relative position of the member within the detected interval. The second detecting device is constituted by a second movable portion mounted on the member and a second fixed portion spaced apart from the second movable portion. The correction device corrects the detected relative position based on a relationship between the absolute position and the relative position stored in a memory.

Abstract: Audio information is read out of a recording medium which records musical pieces as audio information. The audio information read out is processed to detect BPM values and positions of beats in the musical piece. A musical piece is reproduced from the recording medium by reproducing audio information in accordance with the detected BPM values and positions of beats. The BPM value indicates the tempo of a musical piece, and the beat indicates a strength of a sound which repeatedly appears in each musical piece. When the audio information is reproduced in accordance with the detected BPM values and positions of beats, the musical piece is reproduced at the correct tempo and beats without giving an unnatural feeling to the listener.

Abstract: An audio signal processor performs a signal processing on the first audio signal and the second audio signal in correspondence with an operation to produce an output. The processor comprises and operation device, a signal processing device and a control device. The operation device is operatively movable between one end and the other end. The one end is associated with the first audio signal and the other end is associated with the second audio signal. The signal processing device performs a signal processing on any one of the first audio signal and the second audio signal to provide at least one kind of predetermined effect. The control device controls the signal processing device so that the effect is provided for any one of the first audio signal and the second audio signal at a predetermined timing based on a position of the operation device and a moving direction thereof.

Abstract: An information playback apparatus is provided, which displays the status of playback in a way more suitable to the human sense as well as detects and then displays as new information the feature characteristic of audio information such as a music selection. The frequency of occurrence of variations in amplitude of audio information to be played back is measured at each predetermined frequency. The measured frequency of occurrence is displayed in a predetermined area of a display unit as the feature information of beat densities with respect to the playback elapsed time of the audio information to be played back. An index display unit is displayed in a substantially circular playback speed display unit. The amount of audio information to be sequentially played back corresponding to elapsed time is divided by a predetermined value to determine a remainder.

Abstract: An information playback apparatus is provided to obtain sound effects by using an optical disc in much the same way an analog record is manipulated. A pressing pressure applied onto a rotatable jog dial is detected by providing a pressure sensing layer to the jog dial. When no pressing pressure is applied onto the jog dial, audio information is played back from an optical disc at a normal tempo. When an end of the jog dial at rest is pressed with a pressing pressure within a predetermined range, a tempo of a playback sound played from the audio information is changed in response to the pressing pressure. When an end of the jog dial at rest is pressed with a large pressing pressure, a tempo of a playback sound played from the audio information is changed in such a manner that playback of a playback sound is stopped eventually.
