Abstract

Perceptual quality of audio is the aural accuracy and fidelity perceived by the listener. It is how humans respond to the accuracy, intelligibility, or fidelity of aural media. High-fidelity audio represents high accuracy and minimal distortion and is the standard against which compression algorithms are assessed. We argue that maintaining high-fidelity audio is not just a technical requirement but is also about respecting the artistry of music production. The primary goal of this thesis is to compare the performance of popular audio codecs including file size and conversion speed of each codec when encoding the same file. A secondary goal will be to demonstrate how much audio quality is affected when subjected to audio compression. With these two comparisons, we aim to establish the argument that when choosing an audio codec it is important to not only consider the technical performance but also the perceptual quality the codec provides.
