How it works
Check the peak first
It applies fixed gain to decoded audio and creates an MP3, up to ±12 dB. It does not repair distortion or normalize loudness.

Raise the level and keep an eye on the peak
Start with a small gain change
Choose an adjustment between −12 and +12 dB and inspect the predicted peak. Listen to a loud passage as well as a quiet one. The waveform illustrates a change in amplitude; a larger waveform does not mean the noise has been removed or the recording repaired.
Understand the warning
A source peaking at −6 dBFS is expected to peak near −3 dBFS after +3 dB gain. If the predicted level exceeds full scale, lower the gain to avoid introducing clipping. The export clips out-of-range samples; it does not transparently recover the missing waveform above that limit.
Choose another workflow for a different target
Fixed gain raises speech and background noise together. It is not noise reduction or LUFS normalization, and it does not make a set of episodes equally loud. If the source is already distorted, reducing its level cannot reconstruct the damaged detail.
−6 dBFS + 3 dB = −3 dBFS
The same adjustment raises quiet passages and background noise too.
Before you export
More volume is not more clarity
Gain also raises noise and cannot restore missing detail. Lower it when the peak warning appears.
Questions people ask
Volume and clipping questions
Is adjusting gain the same as loudness normalization?
No. AudioCut applies fixed gain to the retained audio. It does not normalize to a LUFS target or remove noise. Listen to quiet passages, check the peaks, and lower the gain if it is too high.
Can increasing volume make unclear audio clearer?
No. Gain makes the whole signal louder, including noise. It cannot restore detail that is missing from the source recording.
What is clipping?
Clipping happens when amplified peaks go beyond the available digital level and can become distorted. AudioCut shows a predicted peak before processing.
How do I avoid clipping when I make audio louder?
Check the predicted peak. If it exceeds 0 dBFS, lower the gain and listen again to joins and louder passages.
Can I lower volume as well as raise it?
Yes. The current gain control runs from -12 dB to +12 dB, so it can make an audio track quieter or louder.
Is this the same as loudness normalization?
No. AudioCut applies the fixed gain you choose. It does not measure or target a broadcast or streaming loudness standard.
Can I adjust audio volume from a video?
You can use a supported video's audio track as the source. The result is an MP3 with the selected gain, not an edited video.
