Pull request overview
This PR introduces a comprehensive sound wave analysis system with both CLI and web interfaces. It implements audio processing functions for waveform analysis, decibel conversion, and dynamic range detection, along with multiple visualization modules using both matplotlib and Plotly. A Streamlit web application provides interactive audio analysis supporting WAV, MP3, and FLAC formats, and a verification script validates analysis accuracy against scipy.
Key Changes
- Added audio analysis and processing modules with decibel calculations and harmonic detection
- Created dual visualization systems (matplotlib for CLI, Plotly for web)
- Developed interactive Streamlit web app for browser-based audio analysis
- Implemented audio format conversion supporting MP3/FLAC via pydub
