How to increase (normalize) audio level in a MP3 file fast?

Hello
How to increase (normalize) audio level in a MP3 file fast?

Just do a Google for "Normalization". A very complicated process.
There are all kinds of factors involved. Type of music (Rock, Classical)
Recording method (Digital, Analog). Just leveling each song to say a
-6 db level doesn't guarantee equal volume perception.
Songs are recorded with differing levels of companding & limiting.
Some tools allow you to do "Batch" analysis, where each songs content
are compared and a "Average" loudness value is determined.
Most Broadcasting uses extensive audio processing. This is how
Radio stations achieve that "Consistent" volume level and songs sound
different than when played from a CD.
I use a program, Adobe Audition (CoolEdit Pro) that has a number
of features to "Normalize/Colorize" audio. There are lots of free tools
available that will allow you to correct your collection's levels.
Just be sure to keep your original songs before Normalizing, since
using Lossy formats can result in some quality degradation.

Use CDex to reincode and set the volume to 100 or use audacity to amplify
to 0.

I want to normalize MP3 files downloaded from www.bbc.co.uk with radio
programs. Some of them are very quiet. I tried to use dbpoweramp to
normalize, but it does not change volume much. SoundForge 6 allows more
options, but is inconvenient and takes much more time.

Try audacity I use it for normalise if I needd to. the lnk is
http://audacity.sourceforge.net/latest/audacity-win/audacity-win-1.2.3.exe.
I asume you are using windows.

Yes, I'm using Windows.

Try audacity I use it for normalise if I needd to. the lnk is
http://audacity.sourceforge.net/latest/audacity-win/audacity-win-1.2.3.exe. I

Does audacity reencode MP3 to increase volume too?

MP3 Gain works well also:

Does MP3 Gain use Fraunghofer or Blade, not Lame codec? The Panasonic states
that my Panasonic SL-SV570 does not support Lame.

Thanks for replies.

Can CDex, MP3 Gain and audacity convert RealAudio to MP3?

You can use ogg files also. but winamp is the only media player that will be
able to play them.
