A Short While is a sound installation which freezes moments in time. It listens for sounds in its environment and selects some to capture, slow down, and play back. It was made in collaboration between myself and Jonah Udall.
It was installed in front of the LEIMAY dance ensemble's Williamburg studio for much of 2021. To install it we mounted the microphone and speaker to the frame of their second-floor window, keeping the box and electronics secured inside the window. While installed it often captured sounds of traffic, passerbys, airplanes, birds, and of course, LEIMAY's windchime!
The installation mostly fits in a wooden box Jonah made. A microphone peeks out of a hole in the front while a speaker wire runs out the side. It requires just one power cable connection. Inside is a Raspberry Pi, a small USB audio interface for the microphone, and a preamp for the speaker. The whole thing is designed to be weather-proof, though this hasn't yet been battle tested.
The software running on the Pi builds on my Rocoder library. Its source code is available here. The program is very configurable so it can be easily "tuned" in the field to fit different environments and noise considerations.
