Audio synthesis is the process of creating sounds using electronic devices or software. It involves generating audio signals through various methods, such as subtractive synthesis, additive synthesis, or FM synthesis. These techniques manipulate waveforms to produce a wide range of sounds, from musical notes to sound effects. Synthesizers are the primary tools used in audio synthesis. They can be hardware devices or software applications that allow users to design and modify sounds. By adjusting parameters like pitch, volume, and timbre, musicians and sound designers can create unique audio experiences for music, film, and other media.
