Jeffrey Rowell-Reverberant Art

Project Ideas

1)Selectable Spring Reverb Two soundboards with high tension springs between them with a controllable damper on each spring. One sound is input on one side and picked up on the other with variable amounts of reverb. The control system would be a set of foot pedals/switches similar to organ foot pedals which would raise dampers off springs to allow them to transmit sound.

2)Variable Reverb Room A room with a microphone and moveable walls/ceiling which would analyze the pitch of voices within it and attempt to change the shape of the room to highlight harmonics in the voice.

3)Sending Morse Code through reverb and then attempting decoding, explore the chaotic mistranslations that would occur given significant signal distortion.

4)Coupled Pendulum Pickups

A pair of guitar pickups are mounted on a set of coupled pendulums, and then set in front of two strings vibrating at close but different frequencies. The output of the pickups is then fed into a loudspeaker mounted close behind the system for feedback.

This is my favorite concept currently due to the combination of simple concepts and extremely complicated output.



7) Wire over Ferrofluid

A wire suspended over ferrofluid, with a current applied based on the output of a set of speakers. The gain on the sound sources is then controlled by the tension on the wire, such that the increase in ferrofluid weight on the wire lowers the gain. This would create a reactive loop of (increase in fluid weight)->(lowering of gain)->(lowering of wire current)->(decrease in fluid weight on wire). Depending on the latency of the system, convergent, divergent or stable systems could be created.

8) Ferrofluid reverberation tracker (most idea credit to Eoin)

Ferrofluid held on a small powerful magnet forms a nice spiky mushroom shape, which is responsive to both motion and wind pressure. A few of these mounted in the ports of subwoofers would create a cool visualization of sounds run through the woofer, as well as pressure changes in the room caused by motion and door openings.
