DDSP: Audio and Music Processing with PyTorch

This workshop is an introduction to audio and music processing with an emphasis on signal processing and machine learning. Participants will learn to build tools to analyze and manipulate digital audio signals with PyTorch, an efficient machine learning framework used both in academia and industry. Both theory and practice of digital audio processing will be discussed with hands-on exercises on algorithm implementation. These concepts will be applied to various topics in music information retrieval, an interdisciplinary research field for processing music-related data. No pre-requisites, but some knowledge of python is assumed.

In-person (CCRMA, Stanford) and online enrollment options available during registration (see red button above). Students will receive the same teaching materials and have access to the same tutorials in either format. However, students will gain access to more in-depth, hands-on 1:1 instructor discussion and feedback when taking the course in-person.
