Acoustic signal processing is a research area that focuses on the analysis, manipulation, and synthesis of sound signals. It involves the use of digital signal processing techniques to process audio signals, primarily for the purpose of enhancing their quality, extracting useful information, and making sound-based systems more efficient and effective. This field is interdisciplinary, drawing on principles from areas such as physics, mathematics, computer science, and engineering to address a wide range of applications including speech recognition, music analysis, noise cancellation, and audio compression. Researchers in acoustic signal processing work on developing algorithms and technologies to improve the performance of audio systems and devices, ultimately aiming to enhance the user experience and enable new applications in areas like healthcare, entertainment, telecommunications, and more.
