Sound synthesis, various methods of sound generation in audio electronics Wave field synthesis, a spatial audio rendering technique, characterized by creation of virtual acoustic environments; Subtractive synthesis, a method of creating a sound by removing harmonics, characterised by the application of an audio filter to an audio signal
Sound waves propagating through a liquid at ultrasonic frequencies have wavelengths many times longer than the molecular dimensions or the bond length between atoms in the molecule. Therefore, the sound wave cannot directly affect the vibrational energy of the bond, and can therefore not directly increase the internal energy of a molecule.
Additive synthesis is a sound synthesis technique that creates timbre by adding sine waves together. [1] [2]The timbre of musical instruments can be considered in the light of Fourier theory to consist of multiple harmonic or inharmonic partials or overtones.
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.
Chemical synthesis using green chemistry promotes the design of new synthetic methods and apparatus that simplify operations and seeks environmentally benign solvents. Key principles include atom economy , which aims to incorporate all reactant atoms into the final product, and the reduction of waste and inefficiencies in chemical processes.
This synthesizer demonstrates the versatility of substrates and the capacity to potentially expand the type of research conducted on novel drug molecules without human intervention. [ 29 ] Automated chemistry and the automated synthesizers used demonstrate a potential direction for synthetic chemistry in the future.
Table-lookup synthesis [12] (or Wavetable-lookup synthesis [13]) 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.
Make Noise Morphagene – a eurorack synthesizer module built around microsound, or granular synthesis, in addition to Musique Concrète-inspired sound on sound audio manipulation [9] [10] Tasty Chips GR-1 - polyphonic granular synthesizer capable of 128 grains per voice, which can add up to a total of 1000+ grains simultaneously [ 11 ]
