The digital witness tape encodes in real time, in mp3 format, at parameters set by the user, the broadcasting of the radio station, arranged by years, months, days and time intervals. An audio file records an hour of broadcasting, the information retrieval being extremely simple. There are two versions of this application: DR Light or Professional.
The difference between the two versions is the DR Professional’s preferential encoding facilities of certain time intervals at different parameters. Thus, the broadcast of the station can be recorded in low quality, but some shows, news or programs that need to be repeated, are recorded in good quality in order to be rebroadcasted without further processing.
