Audio Archiving Solution for SRG SSR

The Swiss Broadcasting Corporation consolidates its audio archiving applications.

The new audio archive of the Swiss Broadcasting Corporation SRG SSR excels in user comfort.

The Swiss Broadcasting Corporation (SRG SSR) has decided to consolidate its applications for the archiving of audio data. To this purpose, the existing PlayinfoPlus application was extended to include music and sound data of all units of SRG SSR. The consolidation simplifies work processes and reduces efforts for the recording of metadata, audio file research and imports, as well as license and maintenance costs. The project also includes a technology upgrade from Visual Basic 6 and Perl to a state-of-the-art .NET and HTML5 platform. A user-centered design approach was chosen to ensure that the web application meets the professional standards of radio editors.

  • Authentication and authorization via SRG SSR's Active Directory
  • Local rich-client application for CD ripping and importing of e.g. local audio files
