Abstract: A method is designed for controlling a total mixing system including a first mixing system and a second mixing system, which are operated in a linked manner. In the method, the first mixing system stores first scene data specifying contents of a mixing process matching a scene. The second mixing system stores second scene data specifying contents of a mixing process matching a scene. The first mixing system transmits a scene recall request to the second mixing system when a recall event of the first scene data occurs. The second mixing system transmits back a recall enabling response to the first mixing system after receipt of the scene recall request. The first mixing system reconstructs the contents of the mixing process on the basis of the first scene data after the reception of the recall enabling response. The second mixing system reconstructs the contents of the mixing process on the basis of the second scene data after the transmission of the recall enabling response.

Abstract: There is provided a signal processing apparatus that enables target devices to be controlled by operating elements to be set so as to match the user's feeling of operation, thus allowing a user to perform operations with ease. A signal from an external device (for example, a recorder) connected to one of a plurality of input ports which is connected to the external device is inputted to a corresponding one of a plurality of input channels through the connected input port. A plurality of faders correspond to the plurality of input channels, respectively. Based on an operation of each fader, a GPII/O transmits a control signal to one of the external devices to be controlled by the operated fader, to control the external device. The external device to be controlled by each fader is determined based on the connections between the input ports and the input channels.

Abstract: Arrangements are made such that a plurality of operators, such as faders, can be set to opposite operational directions. When any one of the operators has been operated in a particular direction, a control value of each of the other operator, set to the same operational direction as the operated operator, is controlled in the same direction as the particular operated direction, while a control value of each of the other operators, set to the opposite operational direction from the operated operator, is controlled in the opposite direction from the particular operated direction. Where control values of a plurality of channels are to be controlled via a collective control controller, each of the channels is set to a forward or inverse operational direction. Thus, even faders that are to be operated in opposite directions can be appropriately operated collectively as a group.

Abstract: A system for playing a selected one of multiple audio tracks recorded in synchronized fashion with a motion picture on an optical disk. The optical disk has encoded on it a mixing master music and effects (“M&E”) track, or a switching master M&E track. Individual audio tracks are provided for language-specific versions of the same motion picture, but these tracks have data recorded in them only where there is dialog. In this way, for many a motion picture, all tracks but masters will have data recorded for well less than half of the running time of the motion picture. When a mixing master is used, it is mixed with a language-specific track when the latter has dialog; the mixing master contains no dialog. If a switching master is used, it may contain dialog recorded with the M&E; when a language-specific track has dialog recorded in it, it also contains M&E and the track is played to the exclusion of the switching master.

The tension plates are urged radially against the guide plates, so that the tighter the screws are secured, the tighter the tension plates are urged against the guide rods and the more frictional resistance is generated when the user moves the slider.

When the total recorded time of music on the disc is longer than the recordable time of the magnetic tape, the recording device stops recording each time the reproduction of each piece of music is finished, rewinds the magnetic tape for a specified period of time, and then starts recording the next piece of music while performing fade-in and fade-out actions on the two adjacent pieces of music during this overlapped recording period, thereby reducing the overall music recording time. This allows all pieces of music on the disc to be dubbed into the magnetic tape within the recordable time of the latter.

Abstract: Two tape decks are connected to a player that plays back a recording medium. The reproduced sound is recorded on two magnetic tapes by the tape decks operating in parallel. During the recording, one of the decks stops earlier than the other because of difference in tape length and issues a tape-end signal. In response to the tape-end signal, the player is controlled to search for and reach the last recorded piece of music while the tape decks are rewound, paused or otherwise controlled singly or in combination in a suitable time sequence. This makes it possible to edit the tapes of different lengths during continuous recording without leaving blank periods on either tape.

A control circuit or audio detecting circuit provides a control signal in accordance with the level of the voice information from the microphone. The control signal controls a selection control circuit to gradually and smoothly vary the mixing ratio of the first signal and the second signal when mixing these two signals.

Abstract: A digital editing system includes first and second memories in which audio data and weighting factor data are respectively stored. The audio data are sequentially retrieved from the first memory and multiplied by corresponding weighting factor data retrieved from the second memory. A coincidence detector detects when predetermined storage locations of the memories are addressed.

The direction of variation of the weighting factor data can be appropriately selected to modify the audio data into a so-called "fade out" of "fade-in" pattern at a desired point of the audio program. A pair of such editing systems is required for editing audio programs from different sources for storing such programs in a pair of first memories.
