Add Album Volume Increase via Replay Gain Tag

[DetlevD]

@James Buist

... I have used foobar2000 to apply ReplayGain to level the volume and have tested with both the "Scan Per File Track" and "Scan Selection as Single Album" However, even if I set the base decibel level from 89db to 94db, It still makes the same adjustment to the ReplayGain tags. I would like to increase the overall volume of all files to prevent me having to play everything at full volume on the iPhone. For some reason many tracks, even at full volume are too quite when using the std earphones (rather than the in ear ones) on a busy street. Foobar ReplayGain seems to decrease all the tracks by 5-7db and I would rather it left them at the same level. ...

Hi James Buist, yes, the ReplayGain method makes a file quietly when ReplayGain is activated within the Player, that means levels down the original volume in order to give the loudness regulator the headroom to work. There is a standard lost of 6dB, that means half the volume, that means the amplifier needs 6dB more power to produce the same volume as without ReplayGain.
Please read directly from the author David Robinson how ReplayGain works.
There is a forum post with following links of interest:
Anyone figure out how to port RG to WMP PEAKVALUE and AVERAGEVALUE?

If you want to do some simple math on the already correct calculated ReplayGain values (basically not recommended), then look into the Mp3tag scripting language. There are functions for adding or multiplying and such more.
Well ... such scripting functions do you find within foobar too.
