In this episode of ACM ByteCast, Bruke Kifle hosts ACM Fellow Roger Dannenberg, a Professor Emeritus of Computer Science, Art & Music at Carnegie Mellon University. Dannenberg is internationally renowned for his research in computer music, particularly in the areas of programming language design, real-time interactive systems, and AI music. Throughout his career, he has developed innovative technologies that have revolutionized the music industry and is known for creating Audacity, the widely known and used audio editor. In addition to his academic work, His other projects include Music Prodigy, aiming to help thousands of beginning musicians and Proxor, aiming to help software developers launch a successful career. Roger is also an accomplished musician and composer, having performed in prestigious venues around the world.

Roger traces his two lifelong passions for computer science and music, and his fascination with the connection between sound, mathematics, and physics. He describes the signal changes in interactive computer music, which once required specialized hardware but has since been replaced by ubiquitous software-based audio processing. Roger and Bruke discuss the promise of AI in music, especially for enhancing creativity and live performance, as well as the challenges of balancing AI with human labor and creativity. Roger also describes his work on the powerful open-source audio editor Audacity (co-developed with former student Dominic Mazzoni), which has democratized music production and is now used by millions of users worldwide. Finally, he talks about some recent projects in music analysis and composition, and reflects on his role as an academic and advisor.

Francesca shares how experiences with multidisciplinary work in computer science drew her to AI and ethics, and the challenges of synchronizing with people from a variety of different backgrounds at IBM. She also talks about her involvement in the development of AI ethics guidelines in Europe. She walks through some of her concerns around building ethical and responsible AI, such as bias, lack of availability, transparency of AI developers, data privacy, and the accuracy of generated content. Francesca emphasizes the importance of researchers working more closely with policymakers and the important role of conferences such as AIES (a collaboration between AAAI and ACM). She also offers suggestions for those interested in getting more engaged in AI ethics and recommendations for people interested in an AI career path, and advocates for common benchmarks that can help evaluate AI.
