hi ,any help or advice would be appreciated. i have compiled a large amount of mp3s and loaded them into foobar.to acheive volume levelling for all the tracks i used replay gain.playback in foobar is fine in regards to levelling ,but when i playback the tracks on other media the levelling isnt being applied and the tracks are still loud/quiet volume wise.what am i doing wrong?
thanks in advance.
Full Version: volume levelling with foobar2000 and replay gain
You used the built-in ReplayGain scanner to write the appropriate tags to the files (specifying their average volume), but you still need a player which can actually use them for playback afterwards.
foobar2000 and a few other applications do it as they are; for other software, there might be some kind of plugin or component for it to work. Or you can use MP3Gain to ("losslessly") alter the MP3 files themselves and they will play with correct volume everywhere.

thanks for reply . i was going to use mp3 gain originally but am i wrong in thinking it just deals with mp3s? i have a fair amount of wma files. suppose i could convert them to mp3. do you know if the volume levelling with mp3 gain is done just as impressively as with replay gain?
The page I linked in my previous post states that MP3Gain uses the same formula as ReplayGain to decide the volume change, so the only difference would be the limitation to 1.5 dB steps for technical reasons (which is not generally noticeable nevertheless).
As for converting the WMA files, the lossy => lossy conversion is never optimal, it would be better to rerip them directly (or find a better warez dump).

thanks alot. 
.i will re-rip the wma files and use mp3 gain.

1.5 dB steps not generally noticeable? I believe you wrote that by mistake, otherwise: Pls. go and see a doctor - you probably need a hearing device.

I've tried to search: http://www.google.com/search?q=1db+noticeable or http://www.google.com/search?q=1+db+noticeable
...and I found:

"A 1dB difference is the smallest change in sound level that is noticeable"
"Minimum noticeable changes in loudness vary from about 0.15 dB to about 10 dB, depending on the type of signal. 3/4 dB to 1 dB is probably a practical increment"
"Audio level is measured in decibels (dB). One dB is the smallest change in level that most people can hear -- the just-noticeable difference. Actually, the just-noticeable difference varies from 0.1 dB to about 5 dB, depending on bandwidth, frequency, program material, and the individual. But 1 dB is generally accepted as the smallest change in level that most people can detect"

And BTW max. difference is actually 0.75 dB (if you round gain to nearest possible value).

You can do this also with foobar (you can permanently "losslessly" change the volume of mp3 files). Use the "Apply TrackReplayGain to MP3 data" in the context menu > ReplayGain

Perhaps a better phrasing would be "completely irrelevant" instead of "generally noticeable".
I have a pre-processor that supports adjusting the channels in 0.5 dB increments. if you sit in the sweet spot and change one channel by 0.5 dB you clearly hear a shift in the soundstage
"A 1dB difference is the smallest change in sound level that is noticeable"
This is not strictly true; a 0.5 dB difference (which shouldn't be there) can spoil ABX tests.

You can surely hear it when comparing, but the difference does not matter for the practical purpose of replaygain, which is to have an overall equal perceived loudness.
