Nonuniform Sampling Theory in Audio Signal Processing

Authors: Wolfe, Patrick J.; Howarth, Jamie

Abstract

The goal of most sampling schemes is to sample the analogue signal of
interest at a regular rate sufficiently high to ensure a perfect
reconstruction principle in theory. Indeed, analysis and subsequent
signal processing is almost always predicated on this requirement.
However, the assumption of uniformly spaced samples is often
invalidated in practice. Here, we describe nonuniform sampling theory,
which provides a framework for the investigation and analysis of such
cases. We review aspects of the theory and describe how it may be
applied to practical problems of interest in audio signal processing,
including those of wow and flutter in the analogue domain as well as
jitter in the digital domain.
