Recording and Processing Personal Voice Signals with Digital Filtering

Record your own voice signal, perform sampling, and visualize time-domain waveforms and spectrograms. Design filters using window function method and bilinear transform based on specified performance metrics, then analyze frequency response. Apply custom filters to voice signals, compare pre/post-filtering results, playback audio, and create a signal processing system GUI.
