System and method for combining language translation with original audio on video or film sound track
First Claim
1. A system for recording the original sound track for a video or film production along with a translation of the original sound track into a different language therefrom while leaving the audio of both the original sound track and the translation at a predetermined audio level which is within the normal hearing range at all times comprising:
- first playback means for providing an audio output in accordance with the original sound track,second playback means for providing an audio output in accordance with the translation of said original sound track,means for time shifting the output of said second playback means relative to that of said first playback means for optimum clarity and comprehension,means for adjusting the audio level of the output of said first playback means to a predesired level which is within the normal hearing range,means for adjusting the audio level of the output of said second playback means to a predesired level which is within the normal hearing range and above the audio level of the output of said first playback means,third playback means for providing an output in accordance with said translation which is advanced in time relative to the output of said second playback means by a predetermined time period,means for combining the outputs of said first and second playback means,means responsive to the output of said third playback means for lowering the level of the output of said combining means during a period of time encompassing said predetermined time period before the appearance of a signal in the output of said second playback means, during the presence of said signal in the output of said second playback means, and a predetermined time period after said signal in the output of said second playback means has terminated, said lowered level being within the normal hearing range, andmeans for recording the output of said means for lowering the output of the combining means.

Abstract
An original film or video sound track and a translation of this sound track into another language are separately recorded and a predetermined positioning timewise relative to the original sound track introduced to the output of the translation to make for best clarity and understanding of the two audio outputs when they are superimposed. The audio levels of the original sound track output and the translation are then set to predesired levels and combined with each other. The combined signal is then fed to an audio compressor which is triggered by an attack signal generated by a second recording of the translation which is advanced in time by 0.5-2.0 seconds relative to the first translation recording. The combined original and translation audio signal is thus ramped down to a lower level a predetermined time period before and during the time the translation audio is present, the sound track level being restored to its original audio level a predetermined time period after the translation audio has stopped. The combined audio signal is then recorded for use as the video or film sound track.

6. A method for combining an original sound track video or film sound track with a translation thereof on a common recording medium in a manner so that both sound tracks are audible and can be understood by a listener comprising the steps of:
-
recording the original sound track and a synchronized translation thereof on separate similar recording devices, time shifting the recordation of the translation relative to the original sound track for optimum clarity and comprehension, separately adjusting the levels of the recordation of the original sound track and the recordation of the translation thereof so that both levels are within the normal hearing range and the level of the recordation of the original is substantially lower than that of the translation, combining the level adjusted recordations of the original and translation, lowering the level of the combined recordation to a level within normal hearing range during a period of time encompassing a short time before each appearance of the translation, during the presence of the translation, and a short time after the end of the translation, and recording the combined recordation signal on said common recording medium. - View Dependent Claims (7, 8)
