Time-Frequency Analysis of Noisy Speech Signals with Denoising and Reverberation Processing

1. Perform time-frequency analysis on noisy speech signals using spectrogram and periodogram methods 2. Design appropriate digital filters (FIR/IIR) for denoising through frequency response analysis 3. Conduct post-denoising time-frequency analysis to evaluate performance metrics 4. Implement a reverberation effect using four comb filters and two all-pass filters with equalizer integration for echo generation
