For the MAIN and MDW categories, the composers of the shortlisted pieces (selected by an interdisciplinary panel of five judges consisting of composers and physicists) will be invited to attend the final concert in Vienna, where the jury will make its final decision, and the winning compositions will be publicly announced.

​

As for the Call4Sounds, an online voting process will start on the five weeks following the submission deadline. The process will be open, so anybody interested will be able to vote for their preferred piece at matter.soundsof.net/vote. At the end of the voting process, the results will be announced by the organisation and the winner of the €2000 prize will be made public. Together with the winning piece, seven additional pieces will be nominated by the organisation to be part of an outdoors interactive installation at the the University of Vienna
