I occasionally edit my tracks in Melodyne with Region FX and want to bounce it down to a normal audio clip again.  However, every time I do it it raises the track 3db.  I can even take a track in a brand new session, so its completely bare no fx, buses, anything, and bounce mono track to mono track and it still raises it 3db. Am I missing something here? I attacked two screenshots showing what Im talking about - you can see the peak levels on the bounced track are 3db higher.
 
Thanks

Check the Pan Law settings, in case that's it.
 

Well, its set to
 
(Default) 0dB center, sin/cos taper, constant power.
 
Plus these are mono to mono, Centered tracks so I wouldnt think that would apply?


Thanks for the suggestion though

I've had this problem with Melodyne for years and have never gotten a good explanation as to why it happens.  I just lower the output volume in Melodyne  by -3db before I bounce back to audio.
 

I typically bounce to clips, not bounce to tracks.
I don't lose or gain any volume that way

Its not specific to MElodyne, it's just why Im doing it that way.  In my example I did it on a blank session with nothing happening and it still bumped it up.  
 
I havent been trying to bounce to clip for this, maybe Ill give that a go, thanks.

I can't see enough detail in your screenshot to know how you're bouncing, but if you bounce a mono track through a stereo bus with 0dB center pan law, you'll get a 3dB gain. You either need to bounce with Source = Tracks or change your pan law to -3dB.
 
I believe there's still an outstanding issue with freezing/bouncing mono synth outputs that also does this, no matter what settings are used, but I don't think it would affect bouncing a Region FX.

I get the same weird behaviour. However, Brundlefly has nailed it - if the bounce Source Category is "Entire Mix", then the mono track is actually going through the stereo output bus before going to the new track. The mono track is therefore copied to both the left and right channel of the output bus before being summed to the new mono track. Double the signal gives a 3dB overall boost. This is NOT intuitive, but it does make sense. As Brundlefly says, setting Source=Tracks is the cure.

 Double the signal gives a 3dB overall boost. Cheers, Peter.

 
Incorrect. Doubling the signal voltage = +6dB in level change.  What you may be getting confused with is a 3dB increase in power sounds twice as loud.

I stand corrected. Thanks. I'm still trying to understand what is happening here. During the bounce process, the output bus has a copy of the mono track in each stereo channel, which is then converted to a mono track to finish the bounce. If the two stereo channels were simply summed, we would have double the amplitude and therefore a 6dB increase. Is this where the pan law comes into play?
 
Cheers, Peter.
