Now when I do all these effects manually I get an awesome sound with which I’m really satisfied.
If I use a chain though, it sounds like I’m talking through a can. I use the exact same effects, the same order and the same settings.
Which version of Audacity? Wine Glass Voices are probably cause by bad Noise Reduction settings. If you have Noise Removal settings instead, you’re using an old version of Audacity.
Might you have pulled on your speaker or headphone cord by accident after applying the Chain to the project? This is the most likely explanation. Does it sound “not through a tin can” if you Edit > Undo the Chain?
I copied the first track (unedited) then I apply the affects manually to the first track and via chain to the second. First sounds good, second doesn’t. That’s it. No variables that might have changed.
I think we will continue to give you blank looks. There must be something you are not telling us about this project. You pressed Solo on this second track, right? You are sure the effects in the Chain are really the same as those you do manually?
Perhaps you should reinstall 2.1.1 from http://audacityteam.org/download/windows/, making sure you enable the “Reset Preferences” box half way through installation. Confirm the reset when you launch Audacity.
If that made a difference, and gave the same result as running the effects manually one after the other, that would suggest there is some problem with Chains.
Until we have some evidence of “before and after” audio files, or even better the project in question, it’s hard to comment.
