Positive dB raises signal level
Increasing gain makes the waveform level larger. Leave enough headroom because an excessive increase can push peaks beyond the available range and cause clipping or limiting in later processing.
Raises or lowers the signal by a chosen number of decibels. Use it for a deliberate gain adjustment; use loudness normalization when you want a target listening level instead.
The volume tool applies a deliberate gain change to the signal. Choose a positive decibel value when the file needs to be louder or a negative value when it needs to be quieter. This is the right control when you know the gain change you want; loudness normalization is more appropriate when the goal is to move perceived program loudness toward a target LUFS value.

Reducing gain is useful when an audio file is consistently too loud relative to the next processing or playback stage.
Gain applies the same level change according to the selected dB value. LUFS normalization targets perceived program loudness and is a different operation.
dB, or decibels, expresses a relative level change. Positive values increase signal gain and negative values decrease it.
Yes. If the source already has peaks near the available maximum, adding too much gain can exceed headroom and create clipping or require limiting.
Use volume change for a known gain adjustment in dB. Use LUFS normalization when you want perceived loudness moved toward a target level.
