What Does "Extract Audio from Video" Mean?
When you extract audio from a video, you're separating the sound track (music, voice, sound effects) from the visual content. The result is a standalone audio file, typically in MP3 format, that you can play on any music player or audio device.
This is commonly called "ripping audio from video" or "converting video to MP3."

Audio Quality Tips for Best Results
1. Match Bitrate to Source Quality
Don't use 320 kbps if your source video only has 128 kbps audio - you won't gain quality, only file size.
2. Consider Your Use Case
- Voice/Podcasts: 128 kbps is sufficient
- Music Streaming: 192-256 kbps is ideal
- Archival/Professional: 320 kbps maximum quality
3. Check Audio Channels
Stereo (2 channels) vs Mono (1 channel) affects both quality and file size.
