Frequently asked questions
What is LUFS and why does it matter?
LUFS (Loudness Units relative to Full Scale) is the standard measurement for perceived audio loudness. Streaming platforms like YouTube, Spotify, and Apple Music normalize audio to around -14 LUFS to ensure a consistent listening experience across all content.
Why should I normalize my audio?
Normalizing ensures your audio plays at a consistent, comfortable volume. Without normalization, videos or podcasts may be too quiet or too loud compared to other content on the same platform, leading to a poor listener experience.
Which audio formats are supported?
You can normalize MP3, WAV, OGG, M4A, FLAC, and AAC files. The output keeps the same format as your input file, so there is no quality loss from format conversion.
Are my audio files uploaded to a server?
No. All processing is done locally in your browser using WebAssembly (ffmpeg.wasm). Your files never leave your device and nothing is stored or transmitted.
