Common questions
What does LUFS measure?
LUFS estimates perceived loudness across a recording. The tool applies gain across the file. It does not compress the dynamics.
Why did a file finish below the target?
The processor caps the sample peak at −1 dBFS. If reaching the loudness target would exceed that ceiling, the tool applies less gain and flags the result.
Can I normalize and convert in one step?
Yes. Choose MP3 or WAV before running the batch to apply normalization and encode each file in the selected format.
