MATLAB Code Implementation for Audio Recording

This audio recording application operates within the MATLAB environment. The program utilizes MATLAB's built-in audio I/O functions, primarily employing the 'audiorecorder' object for capturing audio signals with configurable sampling rates (typically 8 kHz or 44.1 kHz) and bit depths. The implementation allows flexible recording durations between 1-6 seconds, achieved through timer functions or loop-based duration control. Following acquisition, the code performs comprehensive signal analysis including: time-domain visualization using plot() functions to display amplitude versus time, and frequency-domain analysis through FFT (Fast Fourier Transform) implementation using fft() and fftshift() functions to generate power spectral density plots. Key features include real-time waveform display during recording and advanced signal processing capabilities for both time-domain and frequency-domain characteristics. The system incorporates automated file saving functionality using audiowrite() function to store recordings in WAV format with customizable filenames and metadata preservation, ensuring compatibility with subsequent processing and analysis workflows.
