This output was created during the study of my marster's degree. The main piece responsible for the effect is the ParticleGPU node within Touchdesigner.
The birthrate and movement of the particles are dictated by the level of the bass within the audio. As well as this, the bass controls the intensity of the light that each particle emits. Finally, the snare of the audio controls the colour. With each snare the direction of the colour ramp and its chosen colour changes, resulting in the different mixes of colour seen in the outputs.
