This repo contains the ENF-WHU audio recording dataset collected around Wuhan University campus and the MATLAB programs for electronic network frequency (ENF) detection, enhancement, and robust estimation, in ENF-based audio forensic applications.

EEG Signal Processing & Enhancement tool using Tkinter GUI. It performs bandpass filtering, EMG noise reduction via Wavelet Transform, and Savitzky-Golay smoothing. Supports EDF file input/output, visualization, and SNR calculation. Processed signals can be saved in EDF format. See README.md for details.

EEG signal preprocessing is essential for improving the quality of brain signals by removing noise and artifacts. It helps isolate meaningful features, making the data more suitable for analysis and classification. This step significantly boosts the performance and adaptability of BCI systems in real-world scenarios.
