Artist Nick Cobby animated a video that shows a contrast in visualizations between a simple piano tune and electronic sounds by monitoring wave forms, via dezeen:
Dezeen Music Project: in this music video by animation designer Nick Cobby, billowing forms are used to visualise a gentle piano solo and spiky geometric shapes appear when electronic sounds are played over the top…
Circular forms expand one after another in time with the piano keys and disperse into alien-like tentacles, lines and dots as the notes resonate.
When the electronic glitches kick in, the visuals dramatically change into sharp, spiky shapes that pulse and distort with the beat.
…”I used a plugin [for visualisation software Particular] called Sound Keys to monitor the waveform of the piano to create the pulses – but with a lot of manual keyframing as well to tweak it,” he said. “I’m a big fan of just using one or two methods to create a whole video, as I think the restriction helps me to be more creative.”
