Doing a favor for a friend and am cleaning up/mastering some old Gospel cassette mixes that were ripped to digital form. There is a fair amount of ambient static (at least -40 to -30 db worth) Yeah I know it ain't trance, but it's still applicable for cleaning up noisy mixes.

These are raw un-mastered mixes in .wav form.

Any ideas on how to best clean up the mix while trying to maintain audio quality?

Also, is there a way to convert a single channel mono signal into L/R Stereo? A few of the songs seem to have been converted on the right channel only...So I was hoping to get at least an L/R Mono if not stereo if I can. Google/youtube yielded nothing specific. What I did try was Mono'ing the /R channel track, then using Mono->Stereo + Stereo enhancement, but I didn't like the results very much.

I've tried a basic de-noizer setup with my standard mastering chain and have gotten decent results, but I can still hear data loss. Is this impossible to fix? I've also made use of Wavelab 7's de-noise utility that analyzes a segment of noise and strips it out, so while the noise was completely removed, the data loss was very audible.

I'm working in Cubase 5 and my chain looks like this :

De-noizer
EQ
Multiband Compressor
PSP audio warmer 2
UV-22HR 16bit High
Limiter

Cheers!
