Source Code for Audio Signal Processing Function Implementation in MATLAB

Source code implementation of audio signal processing functions using MATLAB. This program incorporates various algorithms and techniques for processing audio signals, including digital filtering (using functions like filter() or designfilt()), noise reduction methods (such as spectral subtraction or wavelet denoising), and sound synthesis approaches (including additive synthesis or frequency modulation). Through signal processing, we can modify frequency characteristics (via FFT operations), amplitude modulation, and audio quality parameters to achieve diverse audio effects. The code structure includes proper input/output parameter validation using nargin/nargout checks, comprehensive error handling with try-catch blocks, and performance optimization through vectorization and preallocation. To enhance code readability and maintainability, the implementation includes detailed comments describing algorithm flow and uses MATLAB best practices like function modularization. This function program demonstrates practical understanding of audio signal processing principles and their application in real-world scenarios such as audio enhancement, effects processing, and acoustic analysis.
