A sound synthesizer is an electronic instrument capable of producing a wide range of sounds. Synthesizers may either imitate other instruments or generate new timbres. They can be played via a variety of different input devices. Synthesizers generate electric signals, and can finally be converted to sound through the loudspeakers or headphones. Synthesizers use a number of different technologies or programmed algorithms to generate signal, each with their own strengths and weaknesses. Among the most popular waveform synthesis techniques are subtractive synthesis, additive synthesis, wavetable synthesis, frequency modulation synthesis, phase distortion synthesis, physical modeling synthesis and sample-based synthesis. Also other sound synthesis methods including subharmonic synthesis used on mixture trautonium, granular synthesis resulting Soundscape or Cloud, are rarely used. Synthesizers are often controlled with a piano-style keyboard. Other forms of controllers resemble fingerboards, guitars, violins, wind instruments, drums and percussions, etc. Synthesizers without built-in controllers are often called sound modules, and are controlled via MIDI or CV/Gate methods.
