Audio Recording and Time-Frequency Analysis

Record an audio segment and perform time-frequency analysis, then play back the recorded audio. For detailed implementation steps, refer to the code comments that include explanations of key parameters and signal processing functions.

When recording audio, ensure you select a quiet environment to obtain clear audio signals. The recording process can be implemented using MATLAB's audiorecorder function with specified sampling rate (e.g., 44100 Hz) and bit depth (16-bit) parameters.

For time-frequency analysis, you can use specialized audio processing software like Audacity or Adobe Audition, or implement signal processing algorithms in MATLAB using functions such as spectrogram for Short-Time Fourier Transform (STFT) analysis with customizable window size and overlap parameters.

When playing the audio, you can use audio player applications like Windows Media Player or VLC media player, or utilize MATLAB's sound or audioplayer functions for programmatic playback with volume control and sampling rate specification.

This information should assist you in completing the tasks of audio recording, time-frequency analysis, and playback. The code implementation would typically involve initializing recording parameters, capturing audio data, applying Fourier transform-based analysis, and implementing playback controls with error handling for device compatibility.
