I've just doing some ABX tests with the sample trumpets1.wav, which you can find at http://www.pcabx.com/product/reference/trumpets1.wav

It's a trumpet sound, with no pre-echo issues, just added harshness on some alt-presets.

My results:

--alt-preset standard: 6/6 p= 1.6%, quite easy
--alt-preset standard -Z : 7/7 p= 0.8%, quite easy
--alt-preset extreme : 7/7 p= 0.8%, quite easy
--alt-preset extreme -Z : 12/14 p= 0.6%, seems more difficult, or I'm more tired
--alt-preset insane: 3 trials, total 20/32 p=14%, quite difficult, I think I can ABX it on optimum conditions, but I can't prove it right now rolleyes.gif . Edit: not so sure I can ABX it...





So, seems that the VBR alt-presets have more room for tuning?

Would gpsycho be any better in this respect?

You mean better in the --alt-presets?

No. Nspsytune has less problems than GPSYCHO if you compensate for some of the other issues nspsytune has, which the --alt-preset vbr modes do very well.
