EBU R128 loudness normalization with two real-world presets — quiet files fixed properly.

Matching two podcast episodes at −16 LUFS step by step

The Audio Normalizer measures perceived loudness in LUFS and adjusts it to a professional target — −16 LUFS for streaming and podcasts, −23 LUFS for broadcast-style deliverables — using the EBU R128 model rather than naive peak boosting. Picture a two-episode podcast: episode one measures −24 LUFS, episode two comes in hot at −11. Run both through the Streaming preset and episode one gets lifted 8 LU while episode two is pulled back 5. Both land at −16. Same volume knob position for the listener, no more riding the dial between episodes — peak tools only see the loudest instant, while this one hears the whole performance.

One habit separates clean results from muddy ones: feed it the best source you have. Normalizing a low-bitrate MP3 that was already squashed just amplifies its artifacts — start from the WAV or the original recorder file when you can. For anything episodic, run every file through the same preset. A series normalized half at −16 and half at −23 sounds like two different shows, even though both are technically correct. A trick worth borrowing from radio: normalize first, then make your creative EQ and compression decisions on the level you'll actually publish at.
