Wobulator Modulator Plugin (AUv3) Wobulator is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic or GarageBand. Overview Wobulator is a stereo chorus / modulation effect with a wobbly twist! The chorus effect is typically achieved by modulating the time of a delayed version of the dry signal, and mixing the two. Typically, these delay times are very short, around 20ms. Wobulator includes a "Wobble" parameter that adds variation to both the rate and depth, which makes the modulation cycle less obvious to the listener. Parameters Active - Toggles the effect On or Off. Delay - Varies the base delay time between 10-100ms. Higher delay times can be used to create ADT (automatic double tracking) type effects. Rate - Sets the base modulation LFO frequency between 0.01 and 2.00Hz. Depth - Sets the amount of base delay modulation. For example, a 50ms Delay, with 50% Depth, will be modulated between 25 and 50ms. Wobble - Sets the amount of variation introduced by an internal wobulation matrix! At extreme settings the unpredictable nature of the resulting modulation can sound almost tape-like. When Wobble is set to zero, Wobulator behaves like a standard chorus effect. Mix - Sets the balance between the dry / input signal and the wet / processed sound. At 50%, the mix is an equal amount of dry and wet. At 100%, you hear the wet / processed sound only, which is good for wobbly tape effects! If the name sounds familiar, Wobulator is an updated version of the WOBULATER module developed for Voltage Modular by Waverley Instruments.
