Frequently Asked Questions
- What does normalizing audio do?
- It raises or lowers the whole file to hit a consistent loudness target (in LUFS), so quiet recordings get louder and uneven ones become balanced — without manually riding the volume fader.
- Which LUFS target should I use?
- −14 LUFS matches YouTube and Spotify, −16 LUFS suits podcasts and Apple platforms, and −23 LUFS is the EBU R128 broadcast standard. When in doubt, −16 is a safe default.
- Is this the same as 'increase volume'?
- Not quite. Change Volume applies a fixed gain you choose; Normalize measures the actual loudness and adjusts to a standard target automatically, with peak protection to avoid clipping.
- Is it free?
- Yes — free, no sign-up, no watermark. MP3/AAC/WAV/OGG process in your browser.
