replaygain - alway loses volume instead of gaining... :(

(1/2) > >>

polluxx2006:
hello,

i understood what replaygain is for - but i dont really understand, why it doesnt work:

in foobar2000 i scanned an older album and applied album gain. but instead of increasing the volume,
gain was set to -3,95db. and as i turned ablum gain on on my player (iriver h320) it gets lower,
NOT louder... can anybody please tell me how this works?

thanks
oliver

Replaygain adjusts track to have a common reference level, which is generally much lower.  Raising the volume digitally can be done, but it usually leads to clipping which renders the track unlistenable. 

Take a look at the replaygain peak value for your track.  Is it much lower then 1?

You might find http://en.wikipedia.org/wiki/Replay_Gain quite useful for info about replaygain.

i did.

okay.. so the only way it makes sense is to scan all albums on my player
and apply album gain to alle the albums, right?

ok, and after that - should i adjust a specific pre-amp gain?

You can use the preamp value to adjust how far down replaygain drops the volume.  Combined with the "prevent clipping" option you won't get distortion.  But if you raise the preamp too much volume might not be equal between different tracks. 

That said, scanning everything is pretty easy.  Add to foobar from your player, start scanning, write back to the files.
