What is MP4?

The most common video container format. Used by YouTube, smartphones, and cameras. Extract audio from any MP4 file instantly.

What is WAV?

Uncompressed audio format. Perfect quality with no data loss. Standard for music production and professional audio work.

Why Convert MP4 to WAV?

If you're pulling audio from video for editing — cleaning dialogue, extracting sound effects, or mixing into a music project — you want WAV. It's uncompressed, universally supported by audio editors, and avoids any additional quality loss from re-encoding to another compressed format.

Frequently Asked Questions

Why extract to WAV instead of MP3 from MP4?

WAV is uncompressed, so there's no additional quality loss during conversion. Choose WAV when you plan to edit the audio. Choose MP3 when you just need a small file for listening.

How much larger is WAV than the audio in my MP4?

Roughly 5-10x larger. The audio track in an MP4 is typically compressed with AAC. Extracting to WAV gives you an uncompressed version that's much bigger but ready for editing.

Can I extract just a portion of the audio?

This tool extracts the full audio track. To trim it, convert first, then use any audio editor to cut the WAV to the section you need.
