that is the tasty aroma of another tutorial baking
I'm going to have to do something about that. I pride myself on being not that easy to *read*. OK, yes I do have a little time in on building the filters now. Pretty damn cool, with some unexpected results from convolving/deconvolving outside of the *norm* (including some hand-drawn IR). The best part: there are a lot of test tone impulses and IRs out there already constructed and available for download. Here's two spots:
for Sound Forge from Sony, and
cAPLOCK's Noisevault.
how do I implement this in practice? Sounds a bit like building convolution reverbs, and I never have had any experience with that either
First of all, Wizky, thanks for 'pushing' me towards loading up the V-Station and Bass Station that I had lying around; dormant and uninstalled. Neat little synths. The oscillator sync sounds great, and they respond to program changes(!).
As for a 'tutorial', I've decided to try to work out one that uses tools that everyone would have on hand. I've got the SIR around here somewhere, and there are some freeware convolution apps as well. Maybe I can just start from available impulse responses, then point in the direction of rolling your own. I'm working off information that I gleaned from Dimension Pro, so there's some things that need to be in place for Rapture use.
One of those things is a "silence.wav". DP has a 98 - Special folder. I don't think that Rapture ever had the same contents; I do believe that I copied it over from DP. The Impulse folder has the same file. At any rate, this "silence.wav" is nothing more than 4,640 samples of ... nothing. Digital silence. It serves as a placeholder for the 'Chain To Next Element' toggle under E1-E3 (-E5 in Rapture). You build your Elements as usual, but then you run them through the last one as a 'cabinet, amp, filter, microphone, reverb', etc. I've had limited success in writing it all to a singular .sfz file, but I'm sure it can be done.
At any rate, here's a 'teaser'. It's taken from one of the Cabinet models, and sketches out how the time domain impulses work:
----------------------------------------------------------------
<region> sample=Impulses\silence.wav
<effect>
type=tdfir
tdfir_impulse=Impulses\
place_your_impulse_here.wav
tdfir_gain=0
tdfir_dry=0
tdfir_wet=100
----------------------------------------------------------------
From what's there, you can deduce a gain compensation adjustment, and the mix of wet and dry effect. This one is 100% wet, because it's 'filtering" the Element before it in the 'Chain To Next Element' configuration.
Edit: More as it comes.
