A MATLAB Program for Acquiring Audio from Microphone and Video from Camera

This documentation presents a MATLAB program specifically engineered to capture audio data from microphone devices and video data from camera sources. The program leverages MATLAB's Data Acquisition Toolbox and Image Acquisition Toolbox to establish real-time connections with audio and video input hardware. Key functions include audiodevice reader for configuring microphone sampling rates and bit depths, and videoinput object creation for camera resolution and frame rate settings. The application supports various audio formats (WAV, MP3) and image formats (JPEG, PNG) through MATLAB's native multimedia processing capabilities. The program's architecture enables flexible customization for diverse applications such as speech recognition using spectral analysis algorithms (FFT, MFCC), image processing techniques (edge detection, histogram equalization), and machine learning implementations (neural networks, SVM classifiers). Through systematic buffer management and callback functions, the program ensures efficient real-time data streaming while maintaining low latency. The modular design allows researchers to integrate custom signal processing algorithms and computer vision techniques, making it suitable for experimental setups in acoustic analysis, facial recognition systems, and multimodal data fusion projects.
