Sound 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. In sound synthesis, different parameters like frequency, amplitude, and waveform shape can be adjusted to shape the final sound. This technology is widely used in music production, film scoring, and video game design, allowing artists to create unique audio experiences that enhance their projects.
