Exploring Sound Generation and Processing in Mechatronic Systems through Digital Signal Processing: A MATLAB-Based Investigation

Digital signal processing (DSP) encompasses various applications such as convolution, censoring, and filtering. These techniques find relevance in diverse fields, including computer games consoles, tone generation for mobile cellular devices, and theatrical performances. For computer engineers facing limited memory budgets in their devices, generating new sounds by convolving with existing sounds or noises becomes a significant challenge. The objective of this paper is to elucidate and demonstrate the generation of sounds through sound and recorded sound processing. These operations form the foundation of DSP, particularly digital filtering. Sound processing involves modifying prerecorded sound clips using different types of digital filters and processors. The entire process, including sound recording and processing, will be implemented and tested using MATLAB, the widely adopted technical computing software. This project aims to provide valuable archival material that complements the learning and expertise of computer engineering students and specialists.
