i managed to fix my computer!

unfortunately it (my computer) crashes at high cpu loads due to the heat here, so i don't use it much, and i am not able to tell if there is a bug or if its just the computer. usually when i step to the 'snare zero' preset from the one before it, it crashes here, always fun to observe before upload. but hopefully the dsp isn't as makeshift as my heatsink adhesive.

universe is very simple. aamof its so simple an early version of the source is on the last page. this uses the same source-filter process as cepstral resynthesis, except driven by synthesis instead of samples. sort of a "simple solution for acoustic approximations ergo universe that really just makes a few weird noises" but with a retarted interface that can be interesting.

because i can't do a fancy graphic interface i have to narrow my data shaping down to a few params, so you see four sets of params to shape contours to populate the arrays. it you want to use it you'll use it so i won't explain it here. teh manual says, observe the default preset in a spectrum analyser and try the contour for mag, to understand the contour.

not teh taj mahal of vst development, eg. the phase based unison voicing would be more "generally awesome" with more computations, teh stereo output could be improed, but i said, do it this way. next time, do it the other way. for casual dsp, it does some things well.


tldr
diffuse horror soundtrack pads at around 10% cpu per voice unless i made some kind of sloppy error that makes it crash if you change the buffer length in which case just diffuse horror

sorry about the brief selection of presets, u mak

Nice to see a new development.

I just reinstalled all my xoxos vst yesterday after having wiped my puter a few months ago.

Not tempted to use the 64bit beta or are relevant sems not compatible yet?

apparently i don't feel like paying for another computer so far.

like i'm glad to have this available as its a modest entry into spectral synthesis, maybe i'll have a go sometime, but primarily interested in satisfying the compulsion to have done one. done it.

retrospective..
the phasing was initially a linear random -+ value added each frame. noisy so added a simple buf += w * (new - buf) filter which sounded lovely. much later i had a hard to trace signal exploding bug and found it was eliminated by clipping the buffer at -1 to +1 about the time i finished patching. i realised i haven't listened to it much since then and wondering how audible the clipping is in the drifting partials. but finished torturing my netbook for this week.

it might be improved by making that filter leaky eg. * .99f instead of clipping but me no try. there are probably many ways to improve it, worked alright, stopped explode. but a better build would develop options.

also the stereo 90 degrees quadrature output thing which is common to so many processes, is not always good with some patches. i think the offet signal could be used for some spacialisation, since the engine has acoustic emulative potential. other things are much more interesting to do at present :) its going to be too hot to run that computer much for months here. fans on, 40 mph gusts. me no develop synth.

i suppose despite the fact that it does something, its a very McCreation eg. you get all or odd partials, no noise phasing covers it. it would have been rgeat if it had been 2002 not 2020.

Many thanks for this one xoxos. I semi-recently got a new machine thus (finally) made the move to 64-bit. I'm yet to look into a bridging solution, but I'll be checking out the new stuff once I get around to it. Really feeling the absence of your plugs. They're the only reason I'm looking into bridging at all.

universe has been updated

heh fun to say. update is internal and in all likelikood doesn't affect performance, something i noticed later. if gate recall was sloppy it's fixed.

at teh present i have sort of a toxic reaction to thinking about some dsp things, having made a lot of errors this weekend due to too much weed and too little sleep. that single minded focus works well until something interrupts you, or you incorporate some source you haven't thought about in a wile and forget about teh little things. i just don't even want to think about it, i did it, it's done. it's easier to explain that than what i was going to explain.


i never liek to share my soruces because teh algorithms are much simpler to talk about and have less baggage than my implementation. after all, most of these algos are so fing simple that they can be typed in entirety in a few lines.

but here is teh source for universe, at least the dsp module for synthedit that does all the signal generation. iirc its about 500 to 600 lines and has several duplicated sections which obfuscate reading, because i probably got a bit tired of typing at some point. seem to lvoe it now tho.

i hate reading source, but maybe that works well for you. making a synthesizer with a phase vocoder engine like this is simple and has significant application.... hth
