Questions
Are my videos uploaded?
No. Your files are processed on your device. We never upload them.
Will louder sound crackle?
No. A limiter holds the loudest moments just under the maximum, so they don't clip. If a video is already loud, a big boost squeezes its peaks, which can sound flatter; choose a smaller amount.
How much louder is 6 dB or 10 dB?
6 dB doubles the strength of the sound wave; most people hear about 10 dB as twice as loud.
What does A standard loudness do?
It measures the whole video's loudness the way streaming services do (in LUFS), then raises or lowers it to the level you pick. −14 LUFS matches YouTube, Spotify, and TikTok; −16 suits podcasts; −23 is the European TV standard.
Does the picture change?
No. Only the sound is re-encoded; the picture is copied as it is, so it keeps its quality and the job is quick.
Can it remove background noise?
No. Making a video louder also makes its noise louder.
