Audio Signal Processing is the manipulation of audio signals to improve or modify sound quality. This field involves techniques such as filtering, equalization, and compression, which help enhance audio clarity and reduce unwanted noise. It is widely used in music production, telecommunications, and broadcasting. In addition to improving sound quality, Audio Signal Processing also enables various applications like speech recognition and sound synthesis. Technologies such as digital audio workstations and audio effects plugins rely on these processing techniques to create and modify audio content, making it essential for musicians, sound engineers, and content creators.
