Audio synthesis is the process of generating sound using electronic devices or software. It involves creating audio signals through various methods, such as subtractive synthesis, additive synthesis, or FM synthesis. These techniques manipulate waveforms to produce different sounds, which can be used in music, sound design, and other audio applications. Synthesizers are the primary tools for audio synthesis, allowing users to shape and modify sounds in real-time. They can emulate traditional instruments or create entirely new sounds. With advancements in technology, software synthesizers have become popular, providing musicians and producers with versatile options for sound creation.
