The modern audio industry seeks individuals who can implement creative tools for audio and music engineers. This course teaches students how to develop audio software and/or applications for music, sound, and audio engineering and assists them in acquiring programming skills for the audio industry. The course consists of four sections: (1) fundamentals of audio signal processing, (2) audio effects used in digital audio equipment (e.g. digital mixers), (3) applied audio signal processing technologies, and (4) Virtual Studio Technology (VST) plugin programming. The sub-topics include (but are not limited to) gain, delay, filter structures (IIR, FIR), EQ, Reverberator, Compressor, Beamforming, Adaptive filtering, VST plugin development. Students will be evaluated through both knowledge on audio signal processing and practical implementation of a VST plugin as a final project.
