About Volume Normalizer

About the Volume Normalizer

The Volume Normalizer brings any audio file to a consistent loudness target using the EBU R128 loudness standard, the same measurement Spotify, Apple Podcasts, YouTube and broadcasters use to judge a delivery. Pick a target — −16 LUFS for podcasts, −14 LUFS for YouTube and music streaming, or −23 LUFS for broadcast — and the tool measures the file, applies the right gain and engages a true-peak limiter so nothing clips.

Normalizing to a published target means your audio sounds as loud as everything else on the platform, so listeners never reach for the volume knob between episodes. With a free account you can normalize up to 50 files at once to a single target — ideal for levelling a whole season or a batch of client deliverables before you ship them.

MP3 gain and volume boosting

If you just need to make a quiet MP3 louder, this doubles as an MP3 gain tool. Instead of guessing at a volume boost, it measures the file and applies exactly the gain needed to hit your loudness target, then peak-limits so a boosted track never clips. That makes it a safer audio normalizer than blunt 'increase MP3 volume' utilities: you get consistent sound leveling and clean peak normalization across every file, not a louder but distorted one.

How to use the Volume Normalizer

  1. Upload a single audio file, or a batch to process together.

  2. Pick the loudness target — podcast (-16 LUFS), YouTube (-14), broadcast (-23) or music streaming (-14).

  3. Download the leveled audio, or measure where it started with the LUFS meter.

Frequently Asked Questions

What LUFS should I normalize to?

Use −16 LUFS for podcasts (Apple/Spotify), −14 LUFS for YouTube and music streaming, and −23 LUFS for broadcast (EBU R128). When in doubt, −16 LUFS is the safe default for spoken-word and podcast delivery.

Will normalizing cause clipping?

No — keep the Prevent clipping option on and the tool applies true-peak limiting, so the output stays under the platform's dBTP ceiling even when it raises the level.

How is this different from the LUFS Meter?

The LUFS Meter only measures and reports loudness; the Volume Normalizer actually changes the file to hit your target. Measure first, then normalize if you are off spec.

LUFS Meter Measure loudness and check platform compliance before you normalize. Voice Quality Analyzer Full 6-point QA: loudness, clipping, noise, silences and clarity. Silence Trimmer Remove dead air and long pauses before publishing.
