volume booster
What is volume booster?
Giving a boost to the volume of an audio or video file, which only Mp4Gain can do, is the easiest way to make that music file (flac, ogg, m4a, wma, mp3, etc) sound better.
It has been widely demonstrated that optimizing the volume of an audio file (music or video) automatically makes it sound better to human ears.
How to make volume booster?
Mp4Gain can very easily give all your audio and video, in all major formats, a boost that increases quality and sounds better.
Obviously at Mp4Gain we have years of experience making increasingly sophisticated algorithms to achieve these results.
normalized
“Normalizing” is adjusting the volume so that its maximum peak is equal to (or a percentage of) the maximum signal available for digital audio. Typically normalizes the file to 100% as the final stage of production to make it as tall as possible and without distortion. Another reason to normalize is to make multiple tracks sound equally loud or have the same average volume.
The “peak” normalization method finds the sample with the largest amplitude in the file. Then normalize with this value as the peak value. When Normalize Peak Level is set to 100% (0dB), the entire file is amplified so that the peak reaches 0dB.
The Perceived Sound Normalization (dBA) method uses A-weighted decibels, which is an expression of the relative loudness of sound in air as perceived by the human ear. The normalization is because the human ear is less sensitive to low audio frequencies (especially below 1000 Hz) than to high audio frequencies.
