got mail ;D (thanks). Nice font by the way !
like pointed out by nightstorm to phoenix (and explained for the sake of sound fonts in general)
- lack of tail : you need to keep the whole decay of the sound with which the hum will be mixed. Similar results are obtained with shortening a sound with a lot of reverb : you might think the volume is close to zero after a while, you cut it and the sound... sounds cut (instead of fade out).
- 1 blaster had a gap (silence), hence "pop" or harsh transition
- some files have saturation (clipping) but that's not pop per say and it adds up to the color (like a maul saber). Not pop per say.
- poweronf for instance is an interesting patchwork (from phoenix or the original sound was like that). There's a big burst of high freq at the very beginning, it sounds like a saturated mike. That "blast" suits well the power "on force" though. Same, not a "click" per say
- the main click, that is *everywhere* is in the hum, at the beginning. I though it was due to the CF audio engine or something but I listened carefully and the click is there in sound forge too (ie it's not looping properly). It's subtle, it's not in the waveform per say, it's in the transition.
This, of course, despite the zero crossing was made properly (good job). I confirmed this with headphones. It's a very subtle pop that occurs when looping or at the transition between the hum and the fx sound.
(I don't have bionic ear, listen to the sound in loop, it's there, even on my vaio internal sound card)
That issue is due to the nature of the chosen sound for the hum : it varies in pitch.
Solution : build the hum loop so that the pitch comes back on its feet. It can be longer if this helps, as long as it beginning and the end match.
As for the other sounds, they have been mixed with a portion of hum which pitch doesn't match with the beginning of the hum neither, so the pop is there.
