about

Pulsar Rays is an acousmatic composition that explores the synthesis of purely artificial sound spaces inspired by natural phenomena. Amongst some of the synthesis techniques used to realize this composition were pulsar synthesis, convolution, and stochastic spatialization–which is the random movement of a sound object within a confined space–to achieve a natural-behaving immersive sonic experience. Additionally, the assistance of a variational autoencoder model, trained on a diverse range of natural sounds, was utilized to evoke a heightened sense of realism when perceiving these purely synthetic soundscapes.

The title, "Pulsar Rays," alludes to the technique of Sonar (sound navigation and ranging), which employs sound propagation for object detection and a better understanding of underwater environments; a technique used by dolphins and bats for millions of years. Inspired by this technique, Pulsar Rays guides the listener through carefully manufactured spaces by the emission of pulsar trains, allowing the listener to perceive and recreate fictitious and at times deceptively familiar spaces.

Pulsar Rays aims to blur the boundary between the perception of natural and artificial sound through the convergence of technology and artistry, hoping to offer a unique auditory experience.
