Wondered if anyone could help here. I'm writting a tune which is for a very small production (64k). The obvious choice here is P61 with 4bit sample packing. On the whole the quality loss isn't some much of an issue, however I've noticed something REALLY anoying about the 4bit delta packing. Some samples (for example my kick drum) end up with a click at the end. I'm guessing thats because the 4 bit delta isn't returning the end of the sample to 0 (centre).
Anyone know a way around this?
I was thinking some way could be to either implement my own 4 bit delta packing routine (hmmmm, time is an issue). Or run a routine after the samples have been unpacked to do a cheeky volume fade at the end of them?
I'd try doing a very short fade out using the tracker sample editor. It should be enough to use 16 samples for that fade which isn't audible (except for the click removal). Techniques involving extension of the sample (adding a "tail") are much more complicated.
Novel has a similar problem when editing a tune on Milkytracker and handing it to me. When I convert it to P6.1 format, some samples either end up in a "feep" or have noisy clicks at the end. He does the same thing Dalton described. Cutting off the sample at the very end.
I've recently learned, that the two first bytes pr. sample needs to be zero, as TP61 keeps repeating them instead of stopping the sample - apparantly so does protracker, so the solution is simply to load the mod in protracker and save it again - voila!
It's like a standard Protracker replay except the pattern position isn't multiplied by 16: pta_SongPos [0..127] pta_PatternPos [0..63]
I think PtPack is superior to The Player 6 (ADPCM smps packing which give better quality than The Player 6 compression, not bugged, adaptive replay) in all case but one: if you're short on chip memory; The Player modules are depacked in real time while PtPack ones are "unrolled" to maximize compression ratio.
Well, Novel has an affinity towards "mobile editing", that is having his GamePark handheld running Milkytracker. Even after he received a hardware donation by Ragnarok/VOZ including a whopping Phase5 1260 ac-ce-le-ra-tor board.
