What does LUFS mean and why does it matter?
LUFS (Loudness Units relative to Full Scale) measures perceived loudness and guides the normalizer to raise or lower gain so every track hits a consistent loudness target.

Volume Normalization FAQ
How is normalization different from compression?
Normalization adjusts the entire file to a LUFS target without reshaping dynamics, while compression changes dynamic range by attenuating peaks and increasing softer parts. Use normalization for uniform loudness before applying dynamics processing.
Which file formats work with this normalizer?
The uploader accepts popular audio formats such as MP3, WAV, M4A, FLAC, and OGG, plus most standard video files. Every upload stays in your browser while the LUFS-aware processing runs locally.
