Cymatics. A demonstration of sand forming cymatic patterns on a metal plate. Cymatics (from Ancient Greek: κῦμα, romanized: kŷma, lit. 'wave') is a subset of modal vibrational phenomena. The term was coined by Swiss physician Hans Jenny (1904–1972). Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of ...
Table-lookup synthesis[12] (or Wavetable-lookup synthesis[13]) (Roads 1996) is a class of sound synthesis methods using the waveform tables by table-lookup, called "table-lookup oscillator" technique. The length of waveforms or samples may be varied by each sound synthesis method, from a single-cycle up to several minutes.
Life and career. Jenny was born in Basel, Switzerland. After completing a doctorate he taught science at the Rudolph Steiner School in Zürich for four years before beginning medical practice. In 1967, Jenny published the first volume of Cymatics: The Study of Wave Phenomena. The second volume came out in 1972, the year he died.
Frequency modulation synthesis (or FM synthesis) is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The (instantaneous) frequency of an oscillator is altered in accordance with the amplitude of a modulating signal. [1] FM synthesis can create both harmonic and inharmonic sounds.
PPG Wave 2.2 front panel. PPG's Wave series represents an evolution of its predecessor by combining its digital sound engine with analog VCAs and 24db per octave VCFs, featuring 8-voice polyphony; and by replacing its nontraditional series of push buttons and sliders with a control panel consisting of an LCD and a more familiar arrangement of knobs.
Digital waveguide synthesis is the synthesis of audio using a digital waveguide. Digital waveguides are efficient computational models for physical media through which acoustic waves propagate. For this reason, digital waveguides constitute a major part of most modern physical modeling synthesizers. A lossless digital waveguide realizes the ...
Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. [1] Individual objects can be detected using the Doppler effect, which causes the received signal to have a different frequency from the transmitted signal, allowing ...
Stochastic screening or FM screening is a halftone process based on pseudo-random distribution of halftone dots, using frequency modulation (FM) to change the density of dots according to the gray level desired. Traditional amplitude modulation halftone screening is based on a geometric and fixed spacing of dots, which vary in size depending on ...
