Detailed Documentation
To read WAV files and extract comprehensive information, MATLAB provides built-in functions for audio processing. The audioread function can be utilized to load WAV files, returning both the audio data and sample rate. For signal visualization, MATLAB's plotting capabilities enable the creation of time-amplitude diagrams using the plot function with properly scaled time axes derived from the sample rate. Furthermore, the Fast Fourier Transform (FFT) can be implemented using MATLAB's fft function from the Signal Processing Toolbox, which converts the time-domain signal to frequency-domain representation. The resulting frequency-amplitude spectrum can be plotted to analyze signal characteristics more deeply. These methods provide a comprehensive approach to understanding WAV file contents and extracting valuable audio information through proper signal processing techniques.
