Hi Steve, IMHO, the swish you have been describing is nearly impossible to remove, with any software. It can be done but it will take days by someone who is /very/ experienced at the task. I once witnessed an operator remove an airplane fly by from a scene and I thought it was almost magic. Basically, he was dealing with Doppler effect but it took this person two days to remove that unwanted fly by form a movie scene using Sonic Classic. I usually get the most swish effect when I'm playing the disk at or near the bottom of the groove. Sometimes, particularly with instantaneous disks, the bottom of the groove is the only place you can capture whats on the disk. That said, is there any way you can work more toward the top of the groove? There's (obviously) more noise at the top of the groove(scratches, scuffs, etc.) but it's the kind of noise that's easier for software to deal with. Work in small increments when it comes to noise reduction processing. Make several passes at reduced settings. Think of peeling an onion, one layer at a time. The process is much more time consuming but the end result is worth it. If you do use this method in RX5, you will have to have the software learn the noise curve each time. FWIW, Sound forge 11 (and several previous versions) will record 32 Bit Float. This should be your default setting for digitizing regardless of the chosen sample rate. Particularly if you plan to do any post processing. Call me old fashioned, but I will not sample rate convert unless it is in even mathematical numbers (88.2K to 44.1K, 96K to 48K, etc.). On my website, I state that I digitize to 2 files simultaneously because I'm not a fan of sample rate conversion. Yes, I know that algorithms have improved over the years and those of you that maintain that you can't hear any difference will not change my opinion on this.
