[78-L] Audacity and off-center transfers

I've done the same for decades, using an extra mat and an extra LP to 
raise the disc. I have an old record weight liberated from the CBC to 
keep everything in place. Too bad so many reissues have veen done with 
nobopdy paying attention to centering.

  I use a piece of 1/4" Styrofoam sheet cut to 12" diameter. Punch or 
cut
  or ream out a hole in the center just big enough to fit over your
  turntable spindle. Put the adapter on the table. The spindle should be
  hidden in the hole. Place an off-center (78rpm) record on the adapter
  with the center holes lining up  The friction between the styro and 
the
  record will be enough to hold the record stationary on the styro no
  matter what speed you're going to play it at. Run the table initially 
at
  33 or 45 and adjust the record by gently tapping along its edge until
  the groove no longer wanders and tracks straight. Then you can play 
the
  record at it's normal speed when digitizing.
  I use a Technics SP-15 table and this trick works every time.
  I've never lost a record due to it's being flung off the machine!
  I don't think Audacity or Audition have an algorithm that allows the
  digital repair of an off-center disc. At least they didn't a few years 
back.
