Tips for Best Results
- MP3 is compressed and produces smaller files, ideal for sharing and storage
- WAV is uncompressed and preserves full audio quality, but creates larger files
- For music or high-quality audio, use MP3 High (320 kbps) or WAV
- For speech or podcasts, MP3 Medium (192 kbps) is usually sufficient
- Extraction time depends on video length and format
