How to extract audio from MP4 on Windows?

When extracting audio from an MP4 video, there are several important things to keep in mind to ensure the best quality, compatibility, and privacy.

1. Audio Format Selection Matters

Choose the right output format based on your needs:

MP3 – Most widely supported and compressed.

WAV – Uncompressed, high-quality, but large file size.

AAC/M4A – Better compression and quality than MP3, often used by Apple devices.

OGG/FLAC – Great for preserving quality, but may not be universally supported.

2. Audio and Video Sync Issues

If the video has variable frame rates or sync problems, extracting audio might result in slight desynchronization or dropouts. Use professional audio extraction tools for better handling.

3. Check for Multiple Audio Tracks

Some MP4 files have multiple audio tracks (e.g., commentary or different languages). Make sure you’re extracting the correct one. FFbmpeg and V1LC let you choose the track index.
