Abstract
The demand for high sound quality is increasing in both entertainment and communications. Consequently, audio restoration algorithms play a critical role in mitigating distortions and interferences that originate from recording processes or arise from imperfect transmission pipelines. This webinar offers an in-depth examination of generative audio restoration algorithms, with a particular focus on diffusion-based techniques for speech enhancement. The presenter will examine how diffusion models can be effectively employed in audio restoration tasks, including methods for conditioning them on visual modalities to improve performance in challenging acoustic scenarios. Additionally, he will explore various diffusion-based approaches, such as flow matching and the Schrödinger bridge, underscoring their significance in the context of audio restoration. The goal is to offer valuable insights into the theoretical underpinnings and practical applications of these advanced techniques.
