Imagine I have 2 audio files. They contain same audio but one of them was amplified using Amplify effect of Audacity. I don't know the value used. Is it possible to calculate exact dB value used to change one file comparing it with original? How?


If the amplification was linear, and didn't result in clipping, then comparing any given peak value (in Audacity) between the two files will give you the information.
