Abstract

This article describes an innovative compositional method based on the use of a sonic time-lapse algorithm to create soundscape audio montages. The method is based on the superposition of short audio samples of 24-hour continuous field recordings carried out in various kinds of wildlife sonic environments. The optimisation of the algorithm focused on the enhancement of gradual crossfade transitions between recorded samples and the use of variable sample durations as a way of recreating a natural sense of evolution of sonic events in time. Future developments of the project will integrate virtual reality interfaces and environmental education projects as part of the time-lapse algorithm machine-learning techniques and also creative tools suitable for multimedia installations.
