Application of equalizers and pitch-shifting: A Simple User-defined Musical Audio Workstation

Abstract

This paper primarily demonstrates a digital audio system (DAS) the idea of which is to enable users to customize the equalization and transposition of their homemade recording as a fairly basic and simple audio workstation. The first section introduces the underlying theories and analyses, accompanied by some brief discussion of the relevant historical and recent trends, while the second section reports the laboratory practice process in Matlab. The completed DAS achieves the intended goals by employing a few relatively straightforward and simplified algorithms, albeit with some less-than-satisfactory artefacts and performance.
