Raising Jake Studios has released Telephone VST2/VST3 plug-ins for Windows (x64).
Telephone emulates the complex sound of a classic analog telephone in one simple plugin. Telephone is not just a bandpass filter - it processes the signal with noise, non-linear distortion and the 8-bit grit of early telephone digital trunk systems - along with the characteristic 300-3300Hz bandwidth filtering.
Raising Jake Studios say "It might read bad sure sounds cool as effect on vocals and even entire mixes."
Also included in the plugin is a stereo/mono mix switch (active when used on stereo tracks) and an output level trim control.
