Objectives and Requirements

The objective of this lab course is to give students a hands on experience in audio processing. Requirements are a solid mathematical background, a good understanding of fundamentals in digital signal processing, as well as a general background and personal interest in audio. Furthermore, experience with PYTHON and NUMPY is required. Experience with the R Programming language is benefitial (beginners tutorial is provided in the course material). The lab course is supervised by members of the AudioLabs team.
