Normalizing audio...
This may take a minute
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.
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.
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.
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.
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.
