Online Volume Booster works on the principle of increasing the overall gain of the audio signal while limiting the audio peaks to 0dB to prevent clipping and distortion.
In other words, it increases the gain on the quieter segments of the audio record while attenuating the peaks, resulting in a more balanced sound output.
