Summary: Analog modular synthesizers popular in the 1960s and 1970s produce sound with electronic devices such as oscillators, amplifiers, filters, and envelope generators linked together by cables. A specific cable configuration (or "patch") produces a distinct sound controlled by a keyboard or sequencer. While digital synthesis has largely replaced analog synthesizers ... with LabVIEW". [Expand Summary] Analog modular synthesizers popular in the 1960s and 1970s produce sound with electronic devices such as oscillators, amplifiers, filters, and envelope generators linked together by cables. A specific cable configuration (or "patch") produces a distinct sound controlled by a keyboard or sequencer. While digital synthesis has largely replaced analog synthesizers, the concepts and techniques of analog synthesis still serve as the basis for many types of synthesis algorithms. Learn about modular synthesizers and use LabVIEW to compose a piece of music by emulating an analog synthesizer. This course is part of the series "Musical Signal Processing with LabVIEW".

Summary: Most musical instruments as well as the human voice create sound by exciting a resonant structure or cavity by a wideband pulsed source. The resonant structure amplifies select frequency bands (called formants) and suppresses (or "subtracts") others. Subtractive synthesis algorithms use time-varying sources and time-varying digital filters to ... with LabVIEW". [Expand Summary] Most musical instruments as well as the human voice create sound by exciting a resonant structure or cavity by a wideband pulsed source. The resonant structure amplifies select frequency bands (called formants) and suppresses (or "subtracts") others. Subtractive synthesis algorithms use time-varying sources and time-varying digital filters to model physical instruments. Learn how to use the DSP capabilities of LabVIEW to implement an interactive time-varying filter, a band-limited wideband source, a vowel synthesizer for speech, a "cross synthesizer" in which a speech signal's spectral envelope is superimposed on a musical signal, and a remarkably life-like plucked string sound.
