Recording 78's at 45 rpm, equalization?

[higlider]

I have several questions about recording 78's at 45 rpm. First my receiver is applying the RIAA equalization, but the frequencies are being changed later by Audacity, is there a proper correction I should apply? Could someone post what that correction is?

Is it better to record to a mono track or a stereo track and then convert to mono?

What is the proper order in which to apply the various corrections and clean up steps? Thanks in advance.

what do you think audacity is changing ?

depends on whether the source is stereo or mono

what are we cleaning up?

if you played a 78 at 45 then the freqs would be too low
and you would need to raise all freqs by 1.733x
and the time would be too short so you would need
to stretch it by that factor also

if it had riaa eq applied then you need to undo that
and then apply whatever eq the 78 actually had
which may vary by year and label

if you have noise pops ticks etc then use the appropriate filter
