Towards equalization of environmental sounds using auditory-based features

Abstract

In this paper we describe methods to assist soundscape design, sound production and processing for interactive environments, like games and simulations. Using auditory filter banks and sound texture synthesis, we develop algorithms that can be integrated with existing audio engines and can additionally support the development of dedicated high-level audio tools aimed at content authoring or transformations based on samples. The relationship between the auditory excitation patterns and the computation algorithm is explained within the context of footstep sounds. Moreover, methods for sound texture synthesis of water streams with artificial expansion of timbre space using auditory filtering techniques are presented. Copyright © 2011 ACM.
