Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
PyDub relies on ffmpeg or avlib for handling various formats, and missing dependencies can lead to unsupported formats.
Loading and processing large audio files can be slow due to memory limitations and lack of optimized streaming APIs.
PyDub requires ffmpeg or avlib to be installed and configured properly, which adds complexity to setup and deployment.
The official PyDub documentation is basic and lacks detailed examples for more complex operations like real-time audio processing or custom effects.
