How do I equalize or normalize all songs (wav) to about the same even levels?
Can they be all processed in batch?

thank you,
Victor

That's what Chris's Compressor does.

http://theaudacitytopodcast.com/chriss- ... -audacity/

It simulates a broadcast compressor system that squeezes everything into the same volume.

It does change the character of some songs, but that's how they work.

The other tools like Effect > Normalize and Effect > Amplify are arithmetic tools and don't work on loudness. If you have a show with lots of expression and a dense dance tune, the dance tune will always come out far louder than the expressive one with the standard tools. So they won't do what you want.

Effect > Compression works somewhere in the middle, but requires you to hand tune the effect and the overall volume before you apply it.

Alright! Thanks for your help, I really appreciate it.
I do have one more problem if I may ask here. When I play the songs either directly from the wav file or from a burnt cd on Foobar,
the artists, track number and title are not displayed the same. Hoe do ID Tag the wav file?

Again, thank you for your help.

You'll need an additional piece of software to produce metadata which is compatible with ID3: an ID3 tag editor, (apparently itunes will do it), or "Mp3tag" [which despite the name does WAV too] ... http://forum.audacityteam.org/search.ph ... tor+itunes

Music CDs do not carry metadata or song titles. They seem to because when you put a CD in the computer, the machine goes on-line and looks up the titles. If you put a fresh Music CD into a machine not connected to the internet, the song titles will be something like: song1, song2, song3.
