MATLAB WAV File Data Reader: A Compact Implementation

This is a compact MATLAB program designed for reading WAV file data. The implementation utilizes MATLAB's built-in audio processing capabilities through the audioread() function, which automatically extracts audio samples and sampling frequency information. Key parameters handled include sampling rate, number of channels (mono/stereo), and bit depth (sample precision), providing comprehensive audio metadata extraction. The program demonstrates practical approaches for audio data analysis by converting raw audio samples into analyzable formats. It covers fundamental audio processing techniques including waveform visualization using plot() function, spectral analysis via FFT implementation, and basic audio statistics calculation. The code structure emphasizes efficient data handling through MATLAB's matrix operations, enabling seamless conversion between time-domain and frequency-domain representations. Through this implementation, users gain understanding of WAV file format specifications while learning essential MATLAB audio processing workflows. The program serves as a foundation for advanced audio applications such as digital signal processing, audio feature extraction using MFCC algorithms, and real-time audio analysis systems. Future enhancements can incorporate audio filtering, noise reduction techniques, and machine learning-based audio classification capabilities.
