Abstract

Advances in audio processing technologies like speech enhancement, audio compression, and hearing aids rely on automatic methods to evaluate whether processed audio sounds good to listeners. However, current computational approaches for assessing audio quality fail to match human perception, leading to systems that optimize for mathematical metrics rather than what actually sounds good to human ears. When engineers…
