Simple Audio Playback Implementation

Starting from MATLAB 2014a, the wavread function is no longer supported and has been replaced by the audioread function. For MATLAB beginners, this transition is straightforward and won't affect basic audio processing workflows. The audioread function provides enhanced audio file reading capabilities with better performance and support for various audio formats. To implement audio reading in newer MATLAB versions, use the following syntax: [audio_data, sample_rate] = audioread('filename.wav'). This function returns both the audio data matrix and the sampling frequency, which are essential for subsequent processing. For audio manipulation and analysis, MATLAB offers powerful functions like spectrogram for time-frequency analysis and fft for frequency domain transformation. The spectrogram function generates visual representations of signal frequency content over time, while fft implements the Fast Fourier Transform algorithm for spectral analysis. To deepen your understanding, refer to MATLAB's official documentation which provides comprehensive tutorials, function references, and practical examples. The documentation covers audio processing workflows from basic playback to advanced signal processing techniques, helping you leverage MATLAB's full potential for audio applications.
