Consistent loudness, episode after episode
Nothing makes a podcast feel amateur faster than listeners riding their volume control — this episode quiet, that guest loud, the intro music blasting. Loudness normalization measures the whole file the way human hearing does (LUFS) and brings it to the standard level, so every episode lands identically in your audience’s ears.
This tool runs the full EBU R128 two-pass process in your browser: measure, then apply a linear gain with true-peak limiting at -1.5 dBTP. Your raw episode never leaves your machine — useful when the recording contains unreleased material or private conversations. Pair it with the noise remover for a complete free cleanup chain before you publish.
Frequently asked questions
-16 LUFS integrated loudness (with true peaks under -1.5 dBTP) is the widely adopted recommendation for stereo podcasts — loud enough for earbuds on a train, consistent with what Apple Podcasts and most players expect. Spoken-word platforms normalize around this level, so delivering it means your episode plays at the same volume as everyone else’s.
A first pass measures your episode’s true integrated loudness, then a second pass applies one precisely calculated, linear gain. Single-pass normalizers adjust on the fly and can audibly pump during quiet stretches; the two-pass approach changes your dynamics as little as possible.
Last. Edit, denoise, and mix first, then normalize the final export so the measurement reflects exactly what listeners will hear. If you re-edit, just normalize again — it takes seconds.
Yes. The loudness normalizer is completely free, with no signup, watermarks, or limits. We make money from our video translation service, not from this tool.
No. The loudness normalization happens locally in your browser using WebAssembly. Your file never leaves your device — you can even disconnect from the internet once the page has loaded.
