Marble White AutoWah is a dynamic auto-wah effect plugin from Antelope Audio, modelled after a sought-after boutique autowah pedal from Finland. Originally based on a vintage rackmount wah circuit and refined to deliver the feel of a real wah pedal, it adds clear and responsive wah textures to guitar and bass recordings.

Responsive Filtering Engine

Marble White features fast tracking and accurate filter response, ensuring every note is enriched with expressive wah movement. The envelope follower reacts naturally to playing dynamics, making the effect feel organic and connected to the performance.

Detailed Sound Shaping

Four dedicated controls — Sensitivity, Bias, Resonance, and Decay — deliver a wide range of auto-wah variations. The bespoke Decay control adjusts the filter frequency fall speed, allowing everything from sustained wah sweeps on every note to more restrained, traditional pedal behaviour.

Real-Time Performance

Powered by the Synergy Core platform, Marble White operates in real time with negligible latency. It can be combined with amp and cabinet emulations for a complete guitar rig within the DAW, without adding CPU load. Available in AAX, VST3, and AU formats.
