### Pitch Estimation

The Pitch Estimation tool is designed to analyze and identify the pitch of spoken audio in lecture recordings. This helps students understand the intonation and emphasis in speech, which can be crucial for grasping the lecturer's key points and nuances.

**How It Works:**
- **Input:** WAV audio signal of speech
- **Processing:** Analyzes the audio to estimate the pitch (fundamental frequency) of the spoken content
- **Output:** Pitch data and optionally a modified WAV file highlighting pitch changes

**Key Features:**

1. **Accurate Pitch Detection:** Uses advanced algorithms to accurately estimate the pitch of speech, capturing the fundamental frequency and its variations over time.
2. **Visualization:** Provides visual representation of pitch contours, helping students see how the pitch changes throughout the lecture.
3. **Intonation Analysis:** Allows for detailed analysis of the lecturer's intonation patterns, emphasizing how different tones and pitches are used to convey meaning.

**Benefits for Students:**

- **Enhanced Understanding:** By analyzing pitch variations, students can better understand the lecturer's emphasis and intonation, leading to improved comprehension of the material.
- **Improved Note-Taking:** Visual pitch contours can help students identify key moments in the lecture where important points are stressed, aiding in more effective note-taking.
- **Speech Pattern Recognition:** Recognizing pitch patterns can help students become more attuned to the lecturer's speaking style, making it easier to follow and anticipate key points.
