Will Copps' Liminal @ Catholic vs ToneShaper

Transitions—from stillness to movement, and from digital to physical realms—make up a large and underappreciated part of our daily lives. Will Copps explores and expands on these moments in his new spatial composition, Liminal, leveraging GPS to weave music into the rich historical environment and topography of Catholic University. Walk the campus and hear sounds change in line with your movement, framing the campus in a whole new way. The app pairs with an immersive, spatial audio/video exhibition in the Salve Regina Gallery, extending the reach of the gallery and its art across the entire campus. Students, faculty, and visitors can download the app and experience a gallery without walls that reframes our daily interaction with the spaces and their expression of beauty, interest, and contemplation. The app is released via TCW. More information can be found via Catholic University at: https://art.catholic.edu/news/exhibitions/index.html; technical help can be found on willcopps.com and TCWav.com.

Create cycles with tone shapes of smoothly varying frequency by plotting frequency at specific times. Tap the library button to pick from a selection of sample tone shapes to get started. Tap in the plot view to add points with coordinates (frequency, time). Drag to move points, but limited by the neighbors time. Alternatively, drag in the draw tab to add points, then apply them to set the points in the plot view. Adjust the frequency range slider to limit the bandwidth. Adjust the duration slider to specify the cycle period. Finally, in the export view you can save the audio to a WAV file with a chosen number of cycles. The duration of the audio is limited by the maximum duration, which therefore also limits the number of cycles in the audio file.
