What do normalization and the limiter do?
Normalization adjusts the overall loudness. It does not remove noise or make every word equally loud. The limiter controls excessive peaks when boosting the signal. Keep it enabled to help prevent overload.
How do I choose the right level?
Start at 100% and adjust in small steps. Listen to the quietest and loudest sections, switching between Original and Edited. Amplification also raises background noise and cannot restore audio already distorted in the source.
Which files are supported?
MP3, WAV, M4A, FLAC, OGG, AAC, Opus and videos with audio. Up to 500 MB per file and 60 minutes of audio.
How long is the result available?
