Frequently asked questions
Does a multiplier of 2 mean twice the perceived loudness?
No. It scales audio amplitude before limiting. Perceived loudness depends on the source, frequency content and listening conditions.
Can boosting repair a distorted recording?
No. The tool changes gain and uses a limiter; it cannot recover details already lost through clipping or noise.
