I see this mentioned in the Foobar thread and have wondered about its use.
I'm happy to adjust the volume as necessary when sitting down to listen to tracks of my choice but we often have Foobar or Slim Devices play in unattended random mode and its very obvious the difference in volume, it's not just slight.
Does anyone on here use this regularly? Is it obviously detrimental to the quality?

I have not used it but indeed certainly when listening to random music the level differences between albums artists can be annoying.
AFAIK each album/song depending on how you set it, is analysed and gets a tag that says how much gain or decrease is needed. One thing is for sure the files won't be 'bitperfect' any more but that is not so much of a problem as DAC's (when upsampling) also are not bit perfect anymore. Nor is that needed. Most players calculate in 32 bits which are unbelievably small steps. So small you need an electron microscope to see them as it were.
In short... theoretically it IS detrimental to the music but in praxis I doubt anyone could be hearing the differences, certainly not when weighing the benefits.
Mind you... there is no 'compression' of dynamic range, so classical music might still sound 'soft' and loudness warred recordings will still sound comparatively loud... even when normalised. The problem is in the recording process.

Mick,
It was deleted along with your account at RG. I got you a new one... couldn't locate the original PandaHarris.
Did manage to find a smaller version of Panda Harris in google cache but only 84 pixels wide and not 'sharp' though.

I'll try it on a sample set of tracks. I was hoping it scanned all albums and set an optimum, didn't realise it needed human intervention, not always a good thing with me Syd

Thanks Claus, I'll try that, so long as the files don't need to be MP3. Syd

Hi Claus, is this a reversable process or once it's done there's no going back? Dicky

Mick, don't worry about it... didn't take me long to find a funny heli.
The replay gain process doesn't alter the original file/sound/volume and that is the 'beauty' of this. What replay gain does is look for the average sound levels of the file (or album whichever you select) and it stores the outcome (the amount of dB's that need to change) in a 'tag' similar to the song info, time info, album art e.t.c. When you select replay gain the playback program that SUPPORTS replay gain simply looks at the tag and reads what needs to be done. The playback program (on the fly) calculates (in 32 bit mostly) how much the original file (which is untouched) needs to be lowered or increased in overall gain.
So the file stays the same and no irreversable damage is done.

In actual fact, some people use this extensively on Ipods which have the EEC volume limitation imposed. They set the replay gain higher so that the Ipod plays louder for less sensitive headphones.
