# 1175 Compressor 4x OS seems to get rid of a decent amount of aliasing when the attack and release are super fast and doing 12dB of gain reduction. 8x is even better. "The attack slider lets you choose from as fast as 20 microseconds (that's 0.02 miliseconds) for transient killing, and extends as slow as 2000 microseconds (2ms). BUT, if you want to use the 1175 with more run-of-the-mill attack settings, open it up in the editor and change the line `slider4:20<20,2000,10>Attack time (usec.)` to `slider4:20<20,10000,10>Attack time (usec.)`."[^1] [JS: 1175 Compressor in REAPER - YouTube](https://www.youtube.com/watch?v=eJM9qZbI0k4) [All Buttons In Is Not A Ratio Control - YouTube](https://www.youtube.com/watch?v=eEQ7K2KVXF4) [^1]: [Jesusonic Effects Documentation - CockosWiki](https://wiki.cockos.com/wiki/index.php/Jesusonic_Effects_Documentation#1175)
