R_WARE PORT OF AIRWINDOWS RECURVE

AW_Recurve is a port of Airwindows Recurve. The algorithms have been refined for the VM environment.

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

Recurve is 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.
