This course aims to provide knowledge on several topics related to the usage of sound for the purposes of human-to-human, human-to-machine, and machine-to- human communication. More specifically the course covers aspects of acoustics and human hearing at a theoretical level as well as practical audio signal processing applications such as spatial audio systems, audio and speech coding, text-to-speech synthesis. The course aims to balance theory and practice in that it will involve students implementing some of the described algorithms, auditory models and replicate some of the auditory effects to be explained during the lectures using high-level languages such as Python (including SciPy and NumPy) and/or Matlab.
