Subject: RE: :MP3 Gain
From: Gvillo, Mike (MXG_at_dolby.com)

You can add multiple folders to the file list.

Open MP3Gain.exe, search for 'album gain' then select 'button bar'.
Those may be the pictures you're talking about, there's also a good
explanation of each type of gain.

I use constant gain because I like to make playlists and I don't listen
to classical, which is probably the most dynamic type of music (lots of
very quiet passages). My jazz albums don't seem to suffer from constant
gain, but that's completely subjective.

MP3Gain is very easy to undo, so feel free to experiment.

Quote from the help page I referred to earlier:
"Album mode volume-corrects a collection of related songs (as they would
appear on a CD, or "album") relative to other collections of songs.
Applying Album gain is like adjusting the volume knob once for each CD
you put in your CD player. The overall volume of the album is adjusted
to the Target Volume, but the volume differences between the mp3s in the
album are preserved.
For example, if you have 3 songs that have volume levels of 86, 91 and
89 dB, then the overall volume of this "album" will probably be around
89 dB. If the Target Volume is set to 92 dB, then when you apply Album
Gain MP3Gain will increase the volume of each of these songs by +3 dB.
With Album mode, you want some songs to be noticeably quieter than other
songs, just like they are on an album. If you're playing a classical CD,
you expect the track with the flute solo to be quieter than the track
with the big full-orchestra finale. Album mode allows you to correct an
entire album while keeping each song's volume level relative to the
other songs."

Off-topic, but quick question (I hope) re: MP3 Gain.

I have a folder on my JBR that has a bunch of MP3s
in it - music from various genres, artists, eras, etc.
Some aren't encoded very well (low levels, etc).

What is the best way to apply MP3 Gain to everything
in that folder so that the low songs get boosted and
the loud ones stay about the same? In other words,
how can I apply gain to those so I can minimize how
often I have to adjust the volume in my car?!

There's Track Analysis and Album Analysis and Album,
Track, and Constant gains. Not sure what to use..

I once saw a good tutorial on MP3 Gain, with some
good graphics somebody did, but I can't find that now.

If there are any good links about this, please send
those on too.

It might be best to reply off-list so we can return
to Rockbox topix. Thx.

Thanks,
Gary
