Subject:I would like to Normalize various wav files so that they have similar output levels

I have various wave files and they all have different output levels.
When I make a CD I would have to turn up some songs and turn down others because the levels don't match.

Does anyone know the answer to this question?

How can I take all these files and convert them to the maximum levels at once?

Thank you

To normalise: Menu bar, Process, Normalise.

To do a bunch of files in oine swoop use the batch converter.

It's all in the manual, and the Help.

If you are collecting songs for a CD it would probably better to bring them all in as waves into an audio editor or Acid Pro so you can hear them together.
WHat I do is importing the (almost) finished stereo tracks inot Acid and first line them up in parallell to check for relative audio levels. Then I line them up in the order they are going on the CD along the timeline in Acid. That way you can get a feeling for the transpositions between tracks as well. I would do all the volume modifications/fade ins/outs/crossfades and render as separate stereo-waves before burning.
Hope this helps

Convert your files to MP3 and use MP3Gain... highly recommended.

MP3Gain

Tired of reaching for your volume knob every time your mp3 player changes to a new song?
MP3Gain analyzes and adjusts mp3 files so that they have the same volume.
It does not just do peak normalization, as many normalizers do. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear.
Also, the changes MP3Gain makes are completely lossless. There is no quality lost in the change because the program adjusts the mp3 file directly, without decoding and re-encoding.

Hey HowhiMZ3,
Can you explain that again in profesional terms: I thought every time you save an MP3 you lose? Or did I mis-read ??????(DATA COMRPESSIOIN)

I think what he's asking is how to normalize WAV files before burning into CD. Converting WAV files into MP3 for the sake of normalizing it then burning into CD is a bad idea IMHO, since the compression/decompression will degrade the quality.

Again.. Make sure your levels are high but never clipping, As for volume levels for different songs .. let your ears be the judge! What sound's good!

Yes, I am quite aware about the losses involed in MP3 compression...

My suggestion was based on the assumption that eventually, he would be converting the rather large waves to a better archival format (I use LAME 3.91 with the RazorLame GUI.) I do not keep wave files around after I have processed them to my liking, though I suppose one could save them to CDR/W: that's just too much time and space for me to deal with. I am quite happy with the results I get from LAME and MP3Gain.

For an in depth discussion of how the MP3Gain program works go to the site.

Thanks for the answers that you have given me.
MP3 gain seems like a good idea.
The batch conversion sounds like a better idea but I don't quite understand how it works yet.

Thanks
