摘要:
An information processing apparatus comprises an operating member used for changing a sound volume, a display device which displays volume data of the sound volume changed in response to an operation of the operating member and a controller which changes the volume data. An indicator indicates level data changed in response to the operation of the operating member.

According to the claimed invention, a DSP is disclosed. The DSP comprises a processing unit for processing the data stream, a first memory coupled to the processing unit for storing a destination volume value, and a second memory coupled to the processing unit for storing a time_determining value wherein the processing unit adjusts the volume of the signal stored in the data stream according to the time_determining value such that the adjustment from a current volume value of the signal to the destination volume value is accomplished within a predetermined time.

The present invention is directed to an audio mixing console having main and secondary faders to independently adjust the maximum and minimum levels of a FADE OUT or FADE IN signal received from an editor associated with the mixer console.
摘要:
An endless manual control for use in automation systems, such as automated recording consoles, which controls levels and other parameters of audio, video and other signals, by generating, storing, sending and receiving electronic control signals. The control's internal circuitry translates control movements into electronic signals describing the control's movements. These electronic signals, including external electronic signals which are inputed during certain modes of operation, are fed into a circuit for updating the circuit's memory of control levels. When either the minimum or maximum control level extreme is reached, the circuitry triggers a mechanism to stop the manual rotation of the control in the direction which had or would have caused that control level extreme to be reached.
摘要:
A digital fader or like device having slidably operable means, such as a touch-sensitive strip, which is manually operable to different settings that are represented by a digital signal. Manual changes in the relative operating position of the slidably operable means produce corresponding adjustments in the digital signal. Display elements are selectively energized by the digital signal to indicate the relative setting of the slidably operable means.
摘要:
A circuit for use with telephony systems or the like for protecting these systems, which may be comprised of integrated circuits, from high transient voltages. The circuit includes a silicon controller rectifier (SCR) having the cathode and anode coupled between an input of the telephony system and earth potential. The gate of the SCR is coupled via a resistor to the cathode thereof and is also returned through a reversed-biased diode to a source of bias potential whereby negative voltage transients are shorted to earth potential such that the integrated circuits as well as the bias potential source are not damaged.
摘要:
A voltage divider device capable of providing any voltage in a preselected range of voltages, which voltage may be set by a touch of the finger is disclosed. The device includes a control element without frictional contacts and a voltage storage circuit controlled by the control element. A circuit including the device is described and embodiments of the device providing a visual indication of the setting of the device are disclosed.
