A synthesizer is an electronic musical instrument that generates and modifies audio signals. Rather than relying on physical acoustic vibrations (like striking a guitar string), synthesizers create sound electronically using oscillators, then shape the tone using filters and envelopes. Synthesizer-like instruments emerged in the United States in the mid-20th century with instruments such as the RCA Mark II. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis, additive synthesis, and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments, and can be synchronized to other equipment via MIDI.
