Whereas in the case of image recording, the evolution from SD to HD and 4K resolution is a constant topic of discussion, current forms of playback for the corresponding audio tracks are still comparatively less popular. This is likely to change with the availability of suitable technology in the consumer sector. 

In 2021, the musikprotokoll offers dynamic streaming of its concerts after the festival. Here, listeners’ head movements are tracked in real time, altering the spatial reproduction of what is heard – the result is an astonishingly realistic acoustic experience.

In cooperation with the Institute of Electronic Music and Acoustics (IEM) at the University of Music and Performing Arts Graz (KUG), the surround sound concert recordings made by ORF will be encoded as binaural audio files and made available online. A video track recorded with multiple cameras will supplement the acoustic event. With the help of a computer, webcam, and headphones, anyone can try out this new method of hearing for a period of one month. Of course, it will still also be possible to experience the entire concert program without a webcam via conventional streaming.
