Designed to emulate an analogue phaser, Audified's STA Phaser plugin can now be downloaded for nothing.
The effect also features a Summing Tube Amplifier (hence the STA name) which mixes the wet and dry signals while also adding a touch of non-linear distortion. Designed primarily to be used as an insert effect, STA Phaser also has a Wet only option (when only the effected signal is processed by the tube circuit) giving you the option to use it on a send bus, too.
STA Phaser works with PC and Mac and comes in VST/AU/AAX formats. Get it now on the Audified website.
If you want another Audified freebie, check out Computer Music magazine, which comes with a special version of the company's STA Enhancer plugin.
