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 beat density detecting apparatus and an information playback apparatus are provided to detect distinctive characteristics that music or the like has and to provide the same as a novel information volume. Playback data read out from an information recording medium, such as an optical disc, and sub-code data containing the information of an elapsed track time indicating a recording position of the playback data are provided to a beat detecting unit and a beat position detecting unit, respectively. The beat detecting unit detects the number of occurrences of a change in amplitude at each predetermined frequency of the playback data, and the beat position detecting unit detects an elapsed track time from the sub-code data. Further, a beat density computing unit finds the number of occurrences with respect to the elapsed track time as the characteristics information of a beat density.

Abstract: A method of reproducing first images and second images simultaneously, synchronizing them with each other. The method includes the processes of: reading first image data representing the first images and second image data representing the second images from a recording medium; storing the first image data into a first memory device and storing the second image data into a second memory device; and separately and simultaneously decoding the first image data and the second image data by using a first decoding device and a second decoding device. In this method, each of the first image data and the second image data is divided into a plurality of data units each having an equal time length and an equal data size, and each of the data units of the first image data and each of the data units of the second image data are alternately arranged on the recording medium.

Abstract: An information playback apparatus is provided, which can provide a sound which sounds natural by controlling an abrupt change in a tempo in the case of random access playback. When a cue point is registered, audio data which makes seamless playback possible is stored into a cue point memory, and further, the beat density of a playback sound being played when the cue point is registered is measured and stored. When the cue point is specified to start random access playback later, a ratio of the beat density (?×DBPM) of a playback sound being played when the cue point is specified and the beat density (DBPMreg) stored in advance is found. Then, the random access playback is started after the beat density of a playback sound to be played after random access playback is started is corrected to be equal to the beat density when a start of the random access playback is specified.

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.
