tl;dw: curve is the simplest, purest form of airwindows recurve with no extra boosts.

sometimes you just want the effect to be lowercase.

the previous plugin slammed home with 6 db of gain in its compression so you could hear it working, and had a clipper on the end in case you wanted to use it as a loudenator.

but maybe you don’t. maybe the best thing for the purest, subtlest compression (the one with no transition point between getting louder and getting quieter, and no edges in the sound anywhere) is to have no gain either. it can still catch overs… most of the time, occasionally not. it can still be heard, probably, but in this form it can sit on nearly any track, unnoticed, quietly balancing levels in lowercase.

you could put it on everything, even though compression multiplies (you get the ratio of all the different compressions, times each other). curve is so calm and gentle that even putting it on all tracks and stems and then the 2-buss still shouldn’t give you a heavily compressed sound.

people have asked whether you can still do airwindows patreon for one dollar a month rather than the ‘fifty dollars a year’ concept. the answer is yes, of course, the per-plugin concept is just to give people something they can relate to. also if you can only spare one dollar a month i would rather help you. but hey, if you gotta share the love i cannot argue as it would be most hypocritical given my own fierce affections for the music producing community.

i was helping clean up my late dad’s house and got a book called archy and mehitabel. whether it influenced curve will have to remain a mystery to the non-literary. suffice to say there’s a dance in the old plugin-monger yet. whatthehell, whatthehell

do 2s and 3s count as uppercase

enjoy curve

TL;DW: Recurve is a special buss compressor with no threshold point.

Recurve.zip(342k)

Sometimes the most amazing things are the simplest.

Recurve is ONE line of code (per channel) plus a bit of implementation. It’s a compressor, and this ‘preview’ look at it is a lot like when Spiral came out: this is Recurve as a ‘black box’, set up for maximum explosiveness and impressiveness. (I’ve got more elegant plugins in the works and this will become a core technique due to its effectiveness and simplicity of coding, so this is the introduction to what the algorithm does)

Recurve works on principles similar to Spiral. It’s using a very high resolution sine calculation to affect the sound, and scales part of itself relative to the loudness of the sample it’s on. It also enjoys similar principles of ‘no sharp transitions, ever, for internal calculations’. In a clipper that means the rate of curvature doesn’t abruptly change, which is the principle behind Spiral. For Recurve, this is applied to the threshold of a compression and whether gain is being turned up or down.

If the signal is super-quiet, the gain doesn’t change. Recurve takes moments of space and ambience between loud sounds, and preserves their character. It doesn’t swoop up in volume: if you need sidechainy pumping, you have to use something else.

If the signal is medium, the gain gets turned up until it hits its max (with Recurve, it’ll exactly double the gain, which is BitShiftGain at its smallest increment. Exactly 6dB of very clean gain boosting things. This isn’t at a threshold: it’s at the most intense spot of a sine curve, so as a waveform passes through this zone it’ll increment the gain smoothly and without any transition points.

If the signal is loud enough, it pushes this curve back through zero to its most negative point, and the sine function delivers a -1, for the maximum gain-cut, which is also scaled by how loud the sample is. So Recurve can cut back an over-loud transient FAST. In fact everything it does is really fast because the lack of transition points and the gradual nature of this sine-triggering lets it react very efficiently without edginess. It also lets through sonority and projection but cuts dull and muted stuff, kind of like Pyewacket, but without Pyewacket’s inherent pointyness.

Sounds complicated? Just listen to stuff and switch it on. This is a preview in extra-dramatic form of an algorithm that’s going to find many uses in Airwindows plugins. It’s the compression equivalent of Spiral for saturation, and it could be adapted in many ways.

The way you get today is a buss-comp or limiter form, running in true (linked) stereo. Mix into it and Recurve will gracefully eat up whatever you send it, even if you push it real hard. There’s a built-in 6dB of very clean boost to show off what it can do, and there’s a clipper on the output in case you get carried away and want to slam it so hard that transient attacks might poke out. And because of Recurve’s curve-and-recurve gain adjustment style, you’ll get none of the usual compression pumping and breathing: it’s just plain different. I hope you like it. There will be more :)

The Airwindows Patreon is how you have this. Turns out keeping Chris working on plugins has benefits: who knew? If you agree, join and help me hang in there, ‘cos in a very real sense we’re all in this together. I’m quite happy to set you up with the plugins first, and we’ll see where that takes us. So far so good :)
