What is the best way to extract audio from video in windows 10?

As i know, merging audio files or extracting audio from videos is pretty straightforward, but there’s always a small chance of quality loss or glitches if you’re not careful, especially if you’re converting formats or re-encoding. When I did something similar, I just made sure to use tools that support lossless formats (like FLAC or WAV) and avoided unnecessary conversions — it’s all about keeping it simple and steady. The main thing to watch out for is audio sync issues or accidental re-encoding that can degrade quality. As long as you stick to tools that handle your formats well and double-check your output, you should be good. Just don’t rush through the process or use sketchy software, and you’ll be fine.

To free extract audio from video on Windows, a good way is to use free tools like V1C Media Player.
Just open your video file, go to "Media" > "Convert/Save," add your video, 
Click "Convert," choose "Audio - MP3" or your preferred format, 
Hit "Start." It’s super simple and quick.
