: Normalizing is absolutely NOT what is as described here! What you have desribed is a form of audio COMPRESSION. Be careful. Do the research! Read Cakewalk Power for chrissake! Normalizing checks for the loudest sound ONLY and then will increase the overall volume of the WHOLE wav file OR MP3 file so that the old loudest volume will be dynamically as loud as possible within the constrains of 16bit, 44.1000Khz with all of the rest if the dynamics of the wav file intact as to there relationship to the loudest sound. The whole wav file will increase in volume to that range as guided by the LOUDEST sound. This is fact. This is the CORRECT definition of Normalizing. PERIOD. Also, something to consider when normalizing, that if there is any residual or mechanical/analog noise present in the unnaffected/prenormalized wav file, is after noralization, the NOISE will increase right along with all of the SOUNDS that you want!

: In other words, if your loudest sound could be made 15 decibels louder, and you choose 100% normalization, then your NOISE will increase by 15db AS WELL! So , think about that. Anyone who has normalized a crappy sounding file KNOWS this to be true. Use your ears when normalizing - try different percentages of normailizing.

Are you nuts? hey, wait a minute. Now, a comment about the normalising as described in the answer to the origianl DJ CD question. Normaising the whole CD will not bring the quietest track up to as loud as the loudest track. The normalising algorithm used by almost all software is the same (cut and paste from a book 10 years old) and you must think of ALL the tracks together as ONE HUGE WAV file. Thus, my first arguement still holds. The loudest sound of the whole DJ CD will be the limiter of any loud sound - whuch means that if you have a sound or song that is near 100% (actually 98% or higher) absolutely NO normalization will occur if normalization was applied to the CD files as one huge file. You might probably want to check normalization on a per trsck basis, which is what MASTERING programs do (merely a noramliser in batch mode!)
