Console8 Updates (and more!)

Hi! If you’re using these plugins, especially on VST, you might want to update them!

Console8.zip(4M)
Console8Hype.zip(2M)
Monitoring3.zip(673k)
PurestWarm2.zip(613k)
Shape.zip(622k)

This is what I’ve been doing for the last couple weeks. It’s always a little like trying to sprint and falling down and spraining your ankle to hit a major bugfix scenario, but this hopefully straightens things out and allows me to return to plugin-making and releasing the cool stuff I’ve got in the pipeline.

So what happened? All these plugins share an experiment I did with PurestWarm and continued with Shape, looking to test it out before trying it in Console8. Turns out the experiment failed, but in such a way that it wasn’t immediately obvious until folks started measuring things. The plugins use an ultrasonic filter (or in Monitoring3’s case, define how Dark works) and since it’s a fixed filter, they try to set up how the filter works in ‘reset’, just once when the whole plugin is created for the first time in your DAW.

In doing that, they use a thing called getSampleRate. You would expect that if getSampleRate() returned a garbage value like ‘zero. zero samples per second. Have a nice day!’ then the plugin would crash or otherwise not get through testing… but these plugins ALSO do a thing where if you’re not running at high sample rate, they switch the filtering off, because it’s not useful running at 44.k or 48k: not enough room to suppress aliasing at those sample rates.

And if the plugin is asking ‘are you under 49 kilohertz in sampling rate?’ and the DAW is apparently saying ‘why yes, I have zero kilohertz! I killed all the hertz! ahahaha!’ and will only give the real value when the plugin actually runs and processes stuff… well then, zero is less than 49k, isn’t it? If the plugin asked ‘oh BTW are you 44.1k or 48k?’ it would’ve figured out something was wrong, but instead they happily just said ‘yeah we’re at low sample rate, don’t run the filter’ on ALL VST PLUGINS no matter what sample rate you were at.

And this affected my mixdown of my track Skronk, and I never knew it.

So now it’s fixed. Please re-download the plugins above (or get the collections of plugins below) and Console8 will use its ultrasonic filtering properly, which it wasn’t on VST.

You might think since it’s ‘ultrasonic filtering’ there would be no change in sound. Uh no :) the point is to suppress aliasing. I think you’ll find it DOES change the sound and make it what it was always meant to be, which also means if you need to recall stuff done in the last couple months and MUST have it be the same, you’ll need access to the original releases (this is an ‘update in place’ so you should replace your old plugins with the new ones and they’ll just automatically work with no changes to your stuff). So, if you go to those plugins’ pages on airwindows.com you’ll find, at the bottom of the post, a link to the original version still downloadable. In every case it’ll be, for instance, Console8original.zip(4M) with the word ‘original’, in lowercase, appended to the zip name.

I would suggest trying the updated version to see if you just like it better, though. I was using the VSTs because on Mac Reaper they’ll run a double precision buss and get slightly more of the sound I want from them. And the update, I think, was very helpful in doing that.

Exciter

TL;DW: Exciter is an Aural Exciter plugin that can be both subtle and extreme.

Exciter.zip(614k)

This plugin isn’t my usual jam, but I’ve been listening to this type of effect all my life. The Steely Dan album ‘The Royal Scam’ wouldn’t be the same without the Exciter effect. And now it’s a free Airwindows plugin!

Note that this is NOT a clone of hardware, or any particular brand. As I usually do, I’ve extracted the guts of the effect and then adapted it so it can be used normally or exaggerated. You’ll find that as you apply the effect, it’ll start off sounding like it does nothing, gets more and more intense and then suddenly blows up into crazy distortion. To use it like a normal exciter, fine-tune it so that it’s just barely making transients ‘pop’. If you’re hearing obvious crunch, you’ve already got it cranked up higher than real-world examples would let you do.

The effect works like this: get a sharp band filter going to extract certain kinds of information. Distort it with a soft clip (I use a sin() function, and some real-world examples used a 4049 hex inverter chip, which does a very similar super soft distort when used as an audio effect: it’s the chip that made up Craig Anderton’s ‘Tube Sound Fuzz’ circuit back in the day, and I still have lots of these chips to play with :D ) Then, once you’ve distorted this bandpass, add just only the distortion elements back into the full bandwidth signal, by subtracting the bandpass again.

Exciter lets you adjust the frequency you’re using, and dial in the amount of effect you want. I’m pretty sure it’ll consistently sound good (not quite natural, but this is ‘late seventies heightened detail’ tone here, it doesn’t have to sound natural) if you’re careful to not crank it too much. And of course this is Airwindows, you can crank it on stuff that doesn’t have much to excite, and blast it on bright stuff to make a distinct form of gritty evil distortion for effect.

A lot of the stuff I like in analog is when transistors and chips are misused and freaking out. You can get tones like that out of Exciter, if you like. You can put it in the middle of uLaw, if you like. I’ve not tried that so you can be the first. I hope you enjoy Exciter :)

ZRegion2 (and ZRegion)

TL;DW: ZRegion2 is an Emu e6400 style Airwindows Region filter, with coefficient smoothing.

ZRegion2.zip(667k)
ZRegion.zip(657k)

Here’s one I might be needing in future, so I’m putting it out for everybody to have!

The Airwindows Z series filters are kinds of digital filtering, with sampler hardware emulation put on ’em for added color and vividness, plus a staggering capacity for gain (folks using the original samplers often internally distorted sound with gain boosts in order to get maximum color out of the Emu filters).

But what if there’s a filter type that didn’t even exist on the original device?

ZRegion is that filter. The original Airwindows Region wasn’t written in the context of an Emu Z emulation, more like just experimentation. It uses the cascading filter stages and distortions in an interesting way: you’re using bandpass filters and distorting them, but Region lets you stagger the bandpass frequencies so that you’re successively distorting through series of different filters. A bit hard to explain, but it lets you distort on midrangey frequencies and soften into the bass, or start out with bass clipping and then exaggerate that effect with higher frequencies.

The reason I might be needing this one is, I can get pretty killer bass tones using it. I’ll set the first filter higher for midrange articulation, set the last filter very low for heavy bass mojo, and it’s instantly a bass-amp type of sound. And if I intend to leave the setting as a fixed setting, ZRegion will give me that with the same flavor as my other Z filters.

But if I want to automate or move the controls as part of the mix…

ZRegion2 comes out at the same time as ZRegion, but note that I’m still putting out ZRegion. This is because ZRegion will always run at lower CPU than ZRegion2, because the first plugin doesn’t do coefficient smoothing. It’s for if you have a fixed tone setting to use, OR if you want to have a slight glitchy/zipper-noise quality on some audio and you’re moving the controls.

If you’re going for automation, the Z2 filters are the ones that interpolate the coefficients across the sample buffer, meaning they’ll make control changes smooth. No crackling! This eats more CPU, but a lot of the fun with these filters comes from actively manipulating them. The original sampler never had a Region filter type, but now you can make believe it did, and produce aggressive and textural bandpass-y effects across a broader range than the original sampler’s ZBandpass. Hope you like it!

PitchNasty

TL;DW: PitchNasty is a primitive pitch shifter that also has primitive time-stretch artifacts.

PitchNasty.zip(615k)

So this is a bit unusual. Though this is a sound mangler, there’s no bit crushing here, and in fact most of the time it’s delivering a very high-res immediate and punchy pitch shift, super clean and tight.

It’s just that the rest of the time it’s throwing a nasty, loud sample-glitch, at audio rates. No, beyond that. It’s throwing digital trash at you so hard it becomes a musical note!

And therein lies the secret of PitchNasty. This plugin brings you the heart of old school digital like your classic Akai stuff, back when they did not have the luxury of doing anything elegantly or nicely. Instead, you got things like time stretches that just plain looped a tight time cycle and overlapped it, producing a weird digital honk. Some folks really seem to crave that stuff, and there’s a reason.

Turns out if you do that, your results tend to be very punchy, direct and intense, except for the weird robotic overtone that’s welded to the sound like it’s a musical note. Things like drums love being timestretched or repitched in this way! It’s a whole retro tone, which PitchNasty starts off with. The crossover is very slightly ‘clever’ in a way the retro stuff isn’t, for the purpose of making it sound more retro and less DAW-like: it keeps the presence very high while slightly masking the high frequency edge of the ‘note’ you get.

But then PitchNasty goes way beyond, in that Airwindows way. You’ve got two pitch controls, one giving you note intervals in half-steps, and the other being a pure pitch bend. They stack, for really high or low bends. Then, there’s a control that’s the same as the classic Akai method of setting the sample buffer size… but for this one, you specify the buffer as a musical note (six octave range). Set it insanely high and you’re basically not able to pitch shift anymore because the buffer’s too small, set it insanely low and it barely registers as a note anymore. And then after that, how about a feedback? How about a feedback that can be cranked to more or less constant regeneration? This gives you horrible wonderful old Eventide noises of many descriptions, or you can use traces of it to make your existing sound more complicated and harmonic-dense.

And then the whole thing’s followed by a Dry/Wet, and you can see that PitchNasty sticks so tightly to the underlying sound that you can get it acting like a giant flanger or strange overtone generator. And that’s the other secret of the crude old Akai-like time/pitch processing: when you don’t have any RAM or CPU to work with, you can only do naive primitive things that happen to sound really immediate, direct, alive. It doesn’t lose the impact of a drum track. If you set it up to thicken a snare by applying, Eventide-like, a 30% layer of pitch up (or down, with feedback), there is no flam or hesitation to the sound like more sophisticated algorithms would have to do. Instead, it’s just THERE in the sound, with a hefty dose of digital gnarliness, but woven right in to make a very 80s composite sound that’s huge and fierce.

If you would like to use this as a time stretch, what you should do is open the source sound in an editor, change the sample rate without resampling until you have the new pitch you want and apply that, resample it back to what your working sample rate is (use a good resampling method, you don’t need to use a bad one), THEN use PitchNasty to re-pitch it to what the target pitch is. That’ll give you the time-stretch artifacts, because they are really just pitch-change artifacts used in a different light. Hope you like PitchNasty!
