Course Description

This course provides an introductory overview of audio synthesis and visual programming using Native Instruments' Reaktor Software.  Students will receive an in-depth look into various audio synthesis methods, including: additive, subtractive, sampling, wavetable, physical modeling, and granular synthesis, as well as the various types of modulation synthesis. Students will also learn about the history of the synthesizer and electronic music, and will take a look at many of the current sound design trends in electronic music.  

Additional topics include:
• Sound + waveform characteristics (Timbre)
• Modulation/filters/envelopes
• Analog + digital signals
• Signal flow
• DAWs/sequencing
• Sound design
• Audio effects
• Production techniques
• Audio warping/FFT 


This course is in adaptive mode and is open for enrollment. Learn more about adaptive courses here.
