I have a player that plays 33 1/3 and 45s. Can I record on 45 and adjust speed with Record Now? if so how?

I don't know if Record Now has options for speed changes.  But here's a piece of freeware that will do what you want: WavMerge.  Record at 45 RPM, then bring your file into WavMerge.  Under the speed change options is one for "RPM" settings.  Set the original to 45, and the new to 78, and it'll do what you want.  I helped Dick Langley write the code to do the speed changes.  It doesn't do any fancy filtering, but I found it to work well for what I needed.  One way to eliminate some of the high-frequency artifacts (mostly inaudible) that occur is to set the output sampling rate to 22.1Ksps, which will eliminate the top octave, of which there's probably no musical information on your 78's anyway.

Hope that helps!
