### Noise Reduction

The Noise Reduction tool is designed to significantly enhance the quality of your lecture recordings by eliminating constant background noise. This ensures a clear and focused listening experience, allowing you to concentrate on the important content without distractions.

**How It Works:**
- **Input:** WAV audio signal with constant background noise
- **Processing:** Applies a noise reduction filter in the time-frequency domain using spectral subtraction
- **Output:** Cleaned WAV audio file

**Key Features:**

1. **Effective Noise Filtering:** Utilizes advanced noise reduction algorithms to identify and remove constant background noise, ensuring a clear and undistorted audio signal.
2. **Spectral Subtraction:** Reduces noise by analyzing the frequency spectrum and subtracting the identified noise components from the signal.
3. **High-Quality Output:** Maintains the integrity and quality of the original recording while effectively reducing unwanted noise.

**Benefits for Students:**

- **Improved Clarity:** Eliminate background noise to enhance the clarity of your lecture recordings, making it easier to understand and follow the material.
