Brian, Having no idea of what to expect in terms of relative difference
between the 4 possible settings of Interpolation, I never even thought to
try anything other than the "default" setting (4th Order, figuring that the
programmer knew what was best as a "default" setting. The output quality is
probably dependent on a large number of considerable factors, wave file
sample quality, probably being the
most important of them all. I recently changed my method making soundfonts,
using one wave file for each key of the compass of the keyboard, 61
instances, instead of, in some cases, 3 keys per
wave file, or, in others, one octave per wave file. I think this makes
Fluidsynth tunings more feasible and correct, unless the computer treats
each note pitch as an individual entity without regard to
the fact that the wave file is "stretched" over three adjacent keys, which,
seemingly, would complicate the issue of calculations for parameters.
Anyway, I changed the Interpolation setting from 4th Order
to NONE. I use a Fluidsynth Reverb setting of Room=9, Width=6, Damping=2,
Level=4, the number is the number of green lights lit in the Classic skin of
jOrgan. The sound is a kind of phenomenal, cathedral-acoustic environment.
The articulation is excellent and, especially, the string stops (which I
think are the most difficult wave files from which to obtain convincingly
good quality. So,
I definitely notice a marked improvement in quality using the NONE setting
on Interpolation. As with all observations, mine are subjective. I think
"LINEAR" produces more "ringing" but this may
be a Reverb factor also. Again, there are so many variables affecting sound
quality that it is difficult to make judgments based on those correlative,
interdependent factors.
I have not tried 7th Order, yet, but will and will let you know what it
does.

Subject: [jOrgan-user] Soundfont - Interpolate
What is the meaning and function of the different Interpolate values on the
Fluidsynth propery?
I see the following, and some dispositions, have difference values selected
here:
1. None
2. Linear
3. Order_4'th
4. Order_7'th
Does this have anything to do with latency or audio quality?
Brian.
