A
synthesiser is an electronic musical instrument
designed to produce electronically generated sound, using techniques
such as additive, subtractive, FM, physical modelling synthesis, or
phase distortion.
Synthesizers create sounds through direct manipulation of electrical
voltages (as in analog synthesizers), mathematical manipulation of
discrete values using computers (as in software synthesizers), or by
a combination of both methods. In the final stage of the
synthesizer, electrical voltages generated by the synthesizer cause
vibrations in the diaphragms of loudspeakers, headphones, etc. This
synthesized sound is contrasted with recording of natural sound,
where the mechanical energy of a sound wave is transformed into a
signal which will then be converted back to mech
