### Abstract

We show how to obtain arbitrary tilings of the time-frequency plane using local orthogonal bases. These bases were recently constructed as a generalization of the cosine-modulated filter banks in discrete time, and local sine and cosine bases in continuous time. Due to the fact that they use a single prototype window, these bases also lead to time-varying tilings. Moreover, they have a fast implementation algorithm, and allow for multidimensional irreducible basis functions. As an example, we show how to design a critical-band system for use in audio coding.
