Technical Review | January-March 2012
Sound types in the system are as follows:
Raw Sound (the original sound file imported to the system from CD, tape or announcer)
Produced Sound (sound file after the production process)
Master sound (Masterised version of the edited or produced sound file) Multi-track edited sound file
Easy edited sound file
Raw and master audio is stored as real sound files. Other audio being stored as virtual sound files composed of the reference information associated with real sound files. If the real sound files are deleted, all the virtual audio that refers to them is partially or completely damaged. Therefore if virtual files are needed to be stored as real sound files, they have to be saved as masters.
Conclusion
The infrastructure of the Radio Automation system that TRT has been using since 2003 (workstations, storage areas,
operating systems etc.) is reaching its limit, both technically and economically. In addition to that, TRT has created its own Linux based Digital Sound Archive System software and technical infrastructure, which it launched in 2010. This new system was not integrated to the Radio Automation System. Therefore a new Linux based Radio Automation System, integrated with the current Digital Sound Archive System, is being developed by TRT engineers and it is planned for launch in the middle of 2012.
