DAW, Digital Audio Workatation which is a non-linear sound editing system, is widely used for the sound post-production. Recently digital mixing consoles are also installed in many post-production studio. By using such these digital sound facilities, the fully digital post-production system has been realized. While this fully digital system is very efficient, some problems are expected because of synchronization. This paper describes the trend of sound post-production with regard to digital technology of sound.
We have developed a Magneto Optical Disk Recorder which applies to record digital video and audio signal without compression. We also have developed a Non-linear Editing System using the Magneto Optical Disk Recorder. This Editing System has easy human interface and makes news editing work speedy.
As the Meteorological Service Law was revised, the "liberalization of forecast" has been put into effect.
