The Spectrum of Sound - Synthesizer
Sound and its perception has a rich mathematical structure that allows us to understand and create sounds by mixing waves. The Spectrum of Sound is an exhibit composed of two parts: a synthesizer and an analyzer. This is the Synthesizer part.
Sound is a vibration of a body perceived by our ears. However, almost no object vibrates at a single frequency, it is always a mixture of vibrations at different frequencies and intensities (the spectrum, a kind of fingerprint that identifies sound timbre).
With this synthesizer, we can create tones by adding pure sine waves.
