Name: Subtractive Synthesis Concepts
ID: m15456
Language: English (en)
Summary: Subtractive synthesis describes a wide range of synthesis techniques that apply a filter (usually time-varying) to a wideband excitation source such as noise or a pulse train. The filter shapes the wideband spectrum into the desired spectrum. This excitation/filter technique well-models many types of physical instruments and the human voice. Excitation sources and time-varying digital filters are introduced in this module.
