AUDI 103 Audio Theory and Systems This course immerses students in the language, theories, and technical knowledge common to all fields in which audio is used. Topics include sound waves and propagation, the analog and digital audio signal, signal analysis and processing (frequency, amplitude and time-based), and basic audio systems (transducers, amplifiers, mixers). To contextualize these theoretical aspects, students are introduced to equipment used in professional audio systems from a technical and functional point of view.
