What is this option in Audio File Processor? And what are the implications of using each setting?? (Sync, Linear, or None)

I read the wiki, but that is for an earlier version that didn't have the option, & I searched this forum for such topic, but couldn't find.

Hope this is OK to post in support

not 100 % sure it is implicated fully
But Sinc / Linear has to do with oversampling. (Defailt is none -eg Off
I must admit, that i do not know the default rate, but the two different modes depends on the very familiar function, that we all know so well:
s^2samplesize - 1 sigma for i samples eq 0 ( 2^samples (dataset(i) over 2(samplesize*2)
Or as Lavry Engineering writes in the whitepaper :
Sampling, Oversampling, Imaging and Aliasing -
a basic tutorial

The Frequency plot for NRZ sampling
"The "sinc problem" (undesirable inband high frequency attenuation) is not the only problem. "
See! You are not the only one having problems!
Now...
All you need from here is 'just' a Phd in physics, then im sure you can read the rest of this 'phasianazing' paper.. :p

What a peasant from darker jutland can hear is that
compared to 'None'
Linear ~ a low-freq filter with low resonance
Sinc ~ a low-freq filter with high resonance

:´)

interesting, I can't hear any difference by ear, and have been using sync mode, assuming that this is the best quality.
