Spline Modeling and Level of Detail for Audio

Abstract

In this paper we propose spline models of audio as the first step toward a hierarchical system of level of detail (LOD) for audio rendering. We describe methods such as cycle interpolation which can produce spline models and approximations of audio data. These models can be used to render output in realtime, but can also be mixed prior to rendering. Examples of audio data simplified to spline models with cycle interpolation can reduce the data to less than 2% of the full resolution data size, with only minor impact to audio quality. We present a sequence of such examples with instrument models. We also introduce the idea of pre-rendered filtering and mixing, based on the B-spline coefficients of the models.
