CS239353B1 - Apparatus for accurately determining relative start, gap, and end of modulation - Google Patents

Abstract

The device is used in radio for editing audio recordings. It allows non-destructive editing of audio recordings. The editing is performed by playing from one tape recorder to another tape recorder. Instead of editing, it combines the relative beginning, gap and end of modulation, while the relative beginning is created on the playing tape recorder and the relative end on the recording tape recorder. The device allows for specifying the relative beginning, gap, end of modulation, arbitrary repeatability, simulated editing without activating the recording process.

Description

239353

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for accurately determining the relative start, gap, and end of moidulation on a magnetophene band by electronically shearing a sound recorder during playback of a sound recording from a single tape recorder to a second tape recorder in a radio broadcasting apparatus.

Until now, devices are not available that allow accurate electronic shearing of studio magnets without auxiliary tracking. Known control system systems employing the time-control code of the SMTP, which is used on television, do not comply with the spill-over operation, because the accuracy of 30 ms is unusable in sound editing. The editing of the recording is done mechanically, by scissors and gluing, which is very laborious or electronically non-replaceable, essentially random.

The above drawbacks are eliminated by the teachings of the present invention, wherein the tape recorder counterparts are provided with hinged pressure rubber rollers that prevent slippage relative to the counting rollers by changing the belt movement both during stop and start and moment of inertia. nostl counting pulleys. The output of the playing magneto-modulation as well as the input and output of the modulation of the recorder are connected via the input modulation switches, and the output of the broadcasting console on the console is connected to an after-hearing system, and the main control block is coupled to the modulation switches further by the tape control. furthermore, with the location circuits the counter, the push button for repeated search and playback of the marked location on the strip, further connected with a switch of the modulation of the recording or pre-playing head of the recording deck, the control block itself comprising push buttons for the selection of the simulated cut, the actual cut Further, the shear start, shear stop, further includes a shear gap adjustment element, between the relative end of the modulation start, further includes selections of selected locations on the tape for the tape and recorder.

The higher effect of the present invention is that the apparatus is made up of conventional studio techniques, tape recorders, a director, an extended control block, additional buttons, and modulation switches. The design of the studio allows you to play from the tape deck by recording on the tape deck through a control console, where corrective and level modulation adjustments can be made, allowing you to make a copy of the audio record where the editing points are it is possible to hear the simulated without activating the recording and when the interconnection is satisfactory, to make the toton connection indeed.

The electronic cut according to the invention can be realized by persons who have no editing experience - editing of sound recordings. No demanding training is required and long-term practice is not required. The device allows for unlimited repeatability of the cut position, its further refinement, in a modest manner.

The drawing shows a device according to the invention.

It consists of a playing tape recorder 2, a recording tape recorder 3, which is provided with flip-flopping pressable rollers 4 to prevent the belt from pre-slipping with respect to the counting rollers 1 during rapid changes in the belt movement, furthermore the control panel 16 is modulated by the listening system 12 and switches 6, 9 of the tape recorders 2, 3, wherein the control of the modulation switches 6, 9 is connected to the control block 25, and the remote control circuits 23, 24 of the tape players 2, 3 are connected to the control block 25, furthermore, the buttons 7, 10 are repeatedly re-searched and marked with the location of the tape, the location and memory circuits 11, 14 are further connected thereto, and a modulation switch 26 of the tape recording head 15, 17 of the tape recorder 3 is connected thereto, The block contains buttons to scroll simulated cut 18, actual cut19 and buttons to start cut 20 and stop cut 21, next it comprises a control element 22 for adjusting the gap between the relative start and the end of modulation in the electronic cut, further comprises switches of selected locations 27, 28 on the strips for mag-netophones 2, 3. In case the magnetophones are provided with buttons 5, 7, 8, 10 of the dallocation and the pain circuits 11, 14, these are then part of the control block 25.

On the recording magnetophone 3, which is a function of playing, whereby the audio of the audio player 3 is derived from the playing head 17, the selected relative end of the audio recording is marked by pressing the button for immediate recording of the audio recording, which is the button 8, similar to By pressing the button 5, we mark the relative beginning of the sound recording by pressing the button 5, by checking this way we check the use of the buttons 7 and 10. The refinement of the relative start and end is done by turning the computer rollers against the door and for this time from the resilient start of modulation is designed such that the continuous modulation is disconnected to the marked location on the belt and then the modulation switch 6 is engaged, a similar relative end is formed so that the modulation is marked on location and beyond. In the following procedure, the strips of magnetophones 2, 3 are preset to match the same lengths of strips marked by the location at the magnetophone 2 to the slot
