Anyhow, I wondered first and foremost whether these +1 peak values are to be expected when adding RG tags directly to Mp3s?
Are they a problem at all and if so how might problems might be caused.
Yes.. replaygain is always about playback
So it goes like this:File A -> Replaygain Scan -> Peak and replaygain values stored as metadata.File is played -> Player changes the gain of the audio according to the replaygain value and other replaygain settings -> audio comes out from the speakers.
I think they swapped the definitionDisable unticked -> "apply gain and prevent clipping"Disable ticked -> "just apply gain"
