Hey Guys, I have a problem after exporting my project in the mixing.
Well before i export, everything is clear and well mixed.
But after the basic exportation(Wave, 44100, 32bits, EntireMix) it looks like there is a compressor or something that cakewalk added in. I Hear the volume go Up and go down, depends how many tracks are playing.
 
Exemple: When an instruments stop playing in a part, the other instrument that keep playing will fade in louder then it was usally playing. Its annoying. Did i checked something or forgot to check something to Bypass that "Auto-Mixing" ?
 
I saw the "What You Hear" options, but there are 3 "what you hear" options. What is good to check before the Exportation ??

Try dropping the bit depth to 16 bits. Standard audio CDs require 44100 Hz and 16 bits. 

Make sure that the "Fast Bounce" option is not selected.  It is only guaranteed to work correctly for audio-only projects.

Check your routing.

Is everything routed to your master bus, either directly or via another bus?

By Master Bus I mean the buss that YOU inserted, don't confuse it with the Main outs

A quick check to make sure nothing's routed directly to the main outs is to mute the master bus, which should make playback go silent. If a track continues to play, that's the one that's improperly routed.

There is no "auto-mix" feature in SONAR. By default it will pass audio unmodified in any way.

With what are you listening to the exported song? I don't think Windows Media Player handles 32 bits so I assume you're imported the audio back into SONAR? And WMP can have a compressor on, IIRC.

Anyway, as suggested above, routing is the first thing to check.

It is just about the only thing I ever change when exporting is the 32 down to 16. 

Then I might change the dither to whatever I'm in the mood for. 


And as said, be careful of how you proof your mixes on a computer. 

I use Win Amp because it's default is normal playback sans stupid effects. 
You should not have your on board sound card enabled either as those are notorious for adding unwanted effects.  Use your interface for all playback. 

Cactus brings up a good point. If you're using an MP3 player or Windows Media Player as a reference, it's entirely possible that the playback systems are responsible for the differences. 

The way to test this is to import your exported file back into the SONAR project into a track of its own and play it back. You can use the exclusive solo feature to switch between the original and exported versions while listening for differences. 

Since you're exporting 32-bit files, you can also perform a null test. Invert the imported version and mix it with the project's main bus. Once levels have been precisely matched, the result should be silence. If it is, then there is no difference between the two file versions and it's the playback system that's confusing you.
