Robert:
I have done some careful on-air tests getting listener evaluations for both
"Punch" and "Quality". The tests were done using a good experimental
design; several observers, blind (they didn't know the filter numbers), and
the four Tx EDSP filters compared in all possible pairs. I use an old Heil
BM-10 boomset and have a rather soft, low voice. Here are the results, by
Tx EDSP filter number:
For "most punchy signal": best-to-worst 1,3,4,2
For "most pleasant-sounding audio" best-to worst 4,3,1,2
So... with my voice and mic, it's filter 1 to bust pileups and filter 4 for
best audio quality. Filter 3 is a good compromise.
Hope this helps
