We present a two-part workshop on Efficient Content Creation and Editing using deep generative models. The first part covers our latest advancements in general-purpose deep generative models. The second part offers interactive demos on content restoration and editing with generative modeling tools. These applications meet professional music industry standards and have been integrated into commercial AI-driven music production tools. Participants are invited to engage in demos, where implementation codes are provided, discuss real-world applications, and explore the potential of these models.
