Re: Why do these number fail linearization?

2007-12-06 by Louis Dina

Eric,

I had the same problem awhile back.  Apparently, QTR looks 
for "enough" tonal difference between steps before it will accept a 
file for linearization.  If the tones are too close together, or if 
there is a reversal anywhere, it rejects the input file.  

Try the 21 step wedge for linearization.  To me, the 51 step is 
probably overkill, and besides the differences are even smaller on 
the 51 step wedge.
