Hi, Charles, RX8 has some new features including a method of compensating for lost high-end--it's an AI/Synthesis thing and I haven't played with it much, but for the right program, it might be useful. If Lou's suggestion about multipath doesn't work (or not enough) I would suggest trying the Deconstruct tool after the Spectral De-noise tool. This allows separate adjustment of the "tonal" and "noise" components of the signal and might improve intelligibility. Since the stereo FM system has FM sum signal on the main carrier and an AM difference signal on the subcarrier, I do think that the summing should help get rid of the noise. The noise is mostly on the AM subcarrier and it was added to the L+R carrier in two polarities to generate the stereo signal. So the stereo signals that you have recorded on the tape really are: 2L+N=(L+R)+(L-R+N) 2R-N=(L+R)-(L-R+N) Now, since the N component is of different polarity in L & R derived signals (what was recorded on the tape), if you sum the two signals from the tape, the N component will cancel: 2L+2R=(2L+N)+(2R-N) Now, we all know that channel gains and responses never match exactly, so you should retain the stereo copy as your preservation master. Then, you should create a mono access copy (still a full-resolution WAV) and adjust the amount of the signals from each tape channel. There should be a point where the noise is minimized as you adjust the gain of the two channels in the mixer summing them to mono. Watch your headroom as you sum things, of course. Hope that helps!
