FAQs

There's already MP4 to MP3 — when do I need WAV?

Choose WAV when feeding Audition/Audacity, running speech-to-text, or remixing — it's the lossless intermediate that stops further generational loss. For just listening, MP3 is fine.

How much bigger is WAV than MP3?

About 10x: roughly 10MB per minute (vs ~2.4MB for 320kbps MP3). Compress back to MP3 when you're done editing.

The audio inside MP4 is lossy — can WAV restore it?

No. WAV preserves everything the source track currently has — no better, no worse. Its value is stopping further loss: every downstream edit stays clean.
