Subband coding is widely used in the field of signal compression. A 32 uniform subbands bank is employed in the MPEG audio standard. In this work a mapping of the audio spectrum onto non-uniform subbands is analysed, with the aim of increasing the perceptual quality of the reconstructed signal.

Abstract
Subband coding is widely used in the field of signal compression. A 32 uniform subbands bank is employed in the MPEG audio standard. In this work a mapping of the audio spectrum onto non-uniform subbands is analysed, with the aim of increasing the perceptual quality of the reconstructed signal.
