Deep learning models for generating audio textures

2020

Abstract

Audio textures are a superset of standard musical instrument timbres that include more complex sounds such as rain, wind, rolling, or scraping. With appropriate modeling strategies, textures can be synthesized under parametric control analogous to the way musical instruments are, and can then become a powerful creativity tools for music making. However, audio textures, with complex structure spanning multiple time scales, are a challenge to model and generate synthetically. They are even challenging to define. Deep learning approaches offer new ways to develop generative audio texture models, and they create different demands on training data than traditional modeling approaches, In this paper we briefly review previous modeling approaches, and attempt to rationalize and converge on a definition of textures using modeling concepts. We introduce a new and growing data set along with a system for managing metadata specifically designed for audio textures. Finally, we report on some re...
