A NOTE ON OUR VIRTUAL MEETING FORMAT:
We will be hosting this meeting using Zoom. Please be sure that Zoom is installed on your preferred device prior to the meeting time (app store for iOS/Android, or the meeting link should prompt you to install on Mac or PC). You can either use the audio on your device, or call in for the audio with your phone (see instructions at the bottom of this message).
We ask that most participants keep their audio and video muted during the presentation. You will be invited to un-mute in turn to ask a question during the Q&A period. This will be explained again at the beginning of the meeting.
ABSTRACT:
The pedagogy of 3D sound spatialization has changed significantly over recent years. An ever-increasing number of hard- and software tools has made the field more accessible to a student population beyond engineering disciplines. With the appearance of new plugins and microphone arrays, spatial audio can now be reliably embedded in standard DAW production workflows. At the same time, the Covid-19 pandemic has complicated access to multi-channel playback systems, and remote instruction generally unfolds in stereo at best.
In this presentation, I discuss how we have addressed these developments in a Spatial Audio class at Columbia College Chicago. It was re-designed in fall 2020 as one of the first 'hybrid' classes at our department. Serving students in our BA Audio Arts, BS Music Technology, and BS Acoustics, the class aims to provide a strong theoretical foundation to a diverse student population through a practice-driven curriculum. All class projects are implemented in a standard DAW, using free (as in beer and speech) VST plugins. Remote instruction focuses on a series of production assignments that students can implement at home on a pair of headphones, using binaural recordings as well as head-related and binaural room impulse responses (HRIRs; BRIRs). These are complemented by a series of on-campus workshops that provide a hands-on experience of sound spatialization on multi-channel loudspeaker arrays by means of higher-order ambisonics and VBAP. Students also rely on department resources for conducting a series of binaural and ambisonic recording assignments. For their final projects, they combine the above techniques to create spatial audio artworks that are informed by an experimental approach to the sonic arts and the history of spatial music.
ABOUT THE PRESENTER:
Florian Hollerweger is an Assistant Professor in Columbia College Chicago's Department of Audio Arts and Acoustics, where he teaches audio theory as well as spatial and networked audio, with a focus on computational applications and artistic practice. Before joining the College, Florian was a Lecturer in Music Technology at the Massachusetts Institute of Technology (2013-17) and Victoria University of Wellington, New Zealand (2011-12) and worked for the automatic audio post production web service Auphonic (2012-13). As an artist and scholar of sound, Florian explores the aestheticization of everyday sonic experience through the creation of acousmatic music compositions and sound installations, situated in a larger historical and theoretical context of the sonic arts. Florian has performed, exhibited, and otherwise presented his work across Europe, the British Isles, the United States, Mexico, New Zealand, and Australia. He holds a Ph.D. in Music and Sonic Arts from Queen's University Belfast, Northern Ireland (Sonic Arts Research Centre), and a Diplomingenieur (M.Sc.) from the Graz University of Technology, Austria (Institute of Electronic Music and Acoustics).
