sound synthesis techniques

Sound synthesis involves creating audio signals through various methods. Subtractive synthesis starts with a rich sound and shapes it by filtering out parts. Additive synthesis builds sounds by combining simple waves like sine waves. Frequency modulation (FM) synthesis creates complex tones by varying one sound wave with another. Wavetable synthesis uses pre-recorded wave shapes that can be scanned through to produce different sounds. Granular synthesis breaks sounds into tiny pieces (grains) and recombines them creatively. Each technique offers unique ways to craft sounds, from realistic instruments to entirely new textures, enabling flexible sound design in music and audio production.
