Dear All, The Sonoj Convention 2017 is now over. I can't believe it all just worked out like this; "Call, and they shall come." The video recordings are here: https://media.ccc.de/c/sonoj2017 Or mirrored on youtube: https://www.youtube.com/channel/UCRETFHZgyoUMyUxz3k9lrZA/videos The musical results of our challenge (make a one minute track integrating a telephone ring sample) are either on archive.org as individual tracks: https://archive.org/details/Sonoj2017CompositionChallenge or you can download them all at once.
