Can someone tell me why in Adobe Audition 2.0 that a mixdown from Multi-track has a 3-4 db reduction in volume from the session sounds?

I've noticed the same thing Jeff. However, with our automation equipment, I have no problem with the cut. I simply add a hard limit on it and press on.

Are you saying the volume is lower on the bounced or "Finished" WAV or mp3 file?

Acoustics are counter-intuitive. If one thing is certain about acoustics, it is that if anything seems obvious it is probably wrong.

[Jeffrey Kafer]

yes, Mike, that's what happens.

Yes, this is a "feature" you might say. I don't know if they fixed it in Audition 3 or not. It doesn't happen to everyone, but if you are one of the lucky ones (like myself) it's consistent.

I've gotten into the habit of exporting the work, then opening that exported file in edit and using the "+2db" preset in the Amplify to bring it back up to the proper level.

Well, that would be a good thing -especily if the mix output -of your working audio file- is close to 0dBFS. Let me explain.

Recording in the digital domain is different than in the analog domain. When we used to record on tape, it was standard practice to record hot in order to saturate the tape, essentally using the tape as a peak limiter. In the digital world this is no longer required. All we need is good clean audio and you can nearly boost it to the moon.

When working in your DAW's ProTools, Logic, Adobe Audition ect.. you're creating your program's Working file and a WAV or AIFF file or what have you.
When you digitally compress a file to a smaller file, you lose some dynamic rage. So if your Working or WAV file is hot (peaking at or above 0dBFS) it will clip in a smaller mp3 file -- and in an analog files, due to intersample peaks.

Here is what mom never told you. When you bounce your file to an mp3, you should be peaking at -4 to -6 dBFS in your working file. This will give you clip free audio. (0 dBFS is assigned to the maximum possible level. A signal that reaches 50% of the maximum level would peak at -6 dBFS.)

There are some programs that do this automatically, this could be a built in feature in Audition.


Louder is not always better.

Mike,
This reduction in amplitude occurs even if you are exporting to a lossless .WAV file. It also occurs with that same export if your original recording was done at -20dB. (not that you would want it that low)

I concur with Bob. Frankly, I've been doing this long enough that I don't need Audition to babysit my volumes. If it's a feature, it's unwelcome.

I understand. It was just a suspicion of mine.
