Synthesizer [ˈsɪnθɪˌsaɪzə]

1. (Music / Instruments) Sound synthesis is the electronic production of sounds—starting from their basic properties, such as sine tones and other simple waves.
Synthesizers are so named because they can emulate, or synthesize, a wide variety of sounds—such as the sound of another instrument, a voice, a helicopter, a car, or a dog bark. Synthesizers can also produce sounds that don’t occur in the natural world. The ability to generate tones that cannot be created in any other way makes the synthesizer a unique musical tool.
2. An analog synthesizer combines voltage-controlled circuits—such as oscillators, filters, and amplifiers—to generate and shape sounds. The amount of voltage is typically related directly to the waveform pitch, with higher voltages equalling higher pitches.



“Creativity is defined as the tendency to generate or recognize ideas, alternatives, or possibilities that may be useful in solving problems, communicating with others, and entertaining ourselves and others.” – Robert E. Franken, Human Motivation
