Evaluation of AI Reverberation on Guitar

Artificial intelligence (AI) technology has been applied to create a range of different sound effects. However, perceptual evaluations of such applications have not yet been fully explored in research studies. This paper focuses on reverberation and we report results from objective measurements and perceptual listening tests in two stages (N=10, N=32). Participants rated samples of solo guitar phrases, taken from a musical context, and processed by either an AI software or by a professional sound engineer. The analysis aims to predict the salient modifications made to reverberation by AI and humans. This study contributes to our understanding of AI in studio music production. Future work will expand to other audio effects, such as compression and equalization.
