[78-L] Acoustic disc playback speed?

[CelticGuitar666 at aol.com]

Luckily for me my wife is trained classical violin player so she is my  
pitch picker. I noticed my challenge was with female opera singers like  Alma 
Gluck etc. but also good for Fritz Kreisler recordings Spike Jones would be  
a challenge especially the toilet seat instruments

I'd also  add A flat, particularly in strictly wind-based groups.  More 
common than  G, as you have to put sax and trumpet parts in 3 or 4 sharps in 
that key, and  key changes can go wild in some  arrangements.

One thing I've found over decades of doing transfers is  that there are no
absolutes. Your best bet is to use a good pitchpipe and  try and adjust the
playing speed to existing keys. E Flat, F, G, B Flat and  C are probably the
most commonly used in popular music. Some Columbias like  Frank Crumit's 
"Lena
from Palesteena" play just fine at  78.

determine correct  playback speed.  I'm aware of the advice to listen for 
certain notes,  judge whether they're sharp or flat and adjust accordingly.  
Which  doesn't help as I'm not a trained musician and I don't have a clue.  I 
 think I can get pretty close with recordings that have singing or voices, 
but  instrumentals are a real challenge.

78s to  WAV files in preparation for a radio show I'll be doing at a local 
college  station.  So I'm understandably concerned about accuracy.  I also  
have the occasional customer bring old acoustic discs for transfer to digital,  
so customer needs are a consideration as well.

Technics  direct drive turntables for playback, so I've got capability to 
adjust pitch  within a +/- 9.9% range.
