Audio Mostly 2020 (AM'20) calls for Papers, Demos, Workshops, and Music & Installations on the topic of audio mostly in extended realities. Audio Mostly is an audio-focused interdisciplinary conference on design, technology, and interaction with sound that embraces applied theory and practice-oriented research. As in previous years, the conference will be in-cooperation with ACM/SIGCHI (tbc). The Institute of Electronic Music and Acoustics (IEM, https://iem.at/) is hosting AM'20 in Graz/ Austria: we are looking forward to an interdisciplinary event extending mostly -but not exclusively- the audio reality!
