Im one of many firm believers in Plangent Processing. Its been used on live Grateful Dead recordings since at least the 1973 Winterland box set released in 2008. That was a ¼ two track tape recording. Theyve used it on their annual box sets, all eleven Daves Picks and some of the Road Trips series. Just read some of the comments about it and Jeffrey Normans work on their Spring 1990 (The Other One) order page.
However, PP is not a fix-all. Born to Run as an example, has other issues besides tape machine errors. In order to build the wall of sound feel, tracks were overdubbed so often the original tracks deteriorated. Thats different from a single undubbed source tape being corrected based on anomalies in the recording machine.
Nothin' left to do but smile, smile, smile (~):}
