Stereo to mono problem

[Village-Idiot]

When converting a file from stereo to mono, Adobe Audition severely suppresses the amplitude of the entire file. [see photo: tinyurl.com/46l96m ] This happens when using both the Convert Sample Rate method, as well as exporting a file from multi-track.

It gets weirder: files that were recorded quite a while back will process this conversion just fine, but newer ones will not. All files are recorded in 16-bit 44100 stereo and saved as a WindowsPCM wav file - so as far as I can tell there is no difference and I'm simply confounded.

And weirder still: I've also tried doing the conversion on a separate computer and that also will not work - so I'm convinced it has something to do with the way the file was recorded or saved, but I have no idea what. Any help provided will get you into heaven, thanks.

It will depend on the what you are summing to mono. If it is something with a lot of phase, you will get a lower volume in mono. This can happen on a number of different types of sources. Keyboards are notorious for this because the 'stereo' information a lot of times is just a stereo chorus that is 180 degrees out of phase on either side. Sum that to mono and it will almost completely cancel out. That will happen on almost any stereo file that is 'wide' sounding.

Thanks for the help! I inverted the left channel and then did the conversion and it worked well enough. You people are real geniuses, God bless the internet!
