You’ve spent time trimming your audio, cutting out the mistakes, and getting everything just right. Now you hit **Export**, and the editor asks: *WAV or MP3?*
If you’re staring at those two options like they’re a different language, don't worry. You're not alone. While they both play sound, they do it in very different ways. Let's break it down in plain English.
The WAV File: Raw, Pure, and Heavy
Think of a **WAV** file like a RAW photo from a professional camera. It contains 100% of the audio data that was originally recorded. There's no "compression," meaning no quality is lost.
- Pros: Absolute best sound quality. Perfect for professional production and archiving.
- Cons: HUGE file sizes. A 5-minute WAV can easily be 50MB.
- When to use: Use WAV if you plan to do more editing later, or if you're producing high-quality music or podcasts.
The MP3 File: Smart, Slim, and Shared
An **MP3** is like a JPEG image. To make the file size small, it uses "lossy compression"—it literally throws away sounds that the human ear usually can't hear. It's incredibly efficient.
- Pros: Tiny file sizes. A 5-minute MP3 might only be 5MB. Plays on literally every device on Earth.
- Cons: Minor loss in quality (though often invisible to most listeners).
- When to use: Use MP3 for sharing on social media, uploading to your phone, or sending via email.
The Golden Rule: Always edit in the highest quality possible (WAV), and only convert to MP3 at the very last step when you're ready to share.
What about Bitrate?
In our editor, you might see settings for bitrate. For MP3s, **128kbps** is standard for speech, but if you want it to sound "CD quality," go for **320kbps**. High bitrate means more detail, but a slightly larger file.
The Bottom Line
For 90% of people, **MP3 at 256kbps or 320kbps** is the perfect balance of quality and convenience. But if you’re a perfectionist working on your next big hit, stick with **WAV**.
