EF-1 Envelope Follower

Wildsync EF-1

The EF-1 Envelope Follower from Wildsync is a great way to derive modulation signals that follow the amplitude of any audio source, bringing a potent and relevant source of modulation to your system. At the input, a gain control lets you adjust the input preamplifier to taste, with a clipping LED indicator for easy level setting. An optional low cut filter can be applied to get rid of unwanted rumble. Controls for setting the threshold at which a gate is generated gives you precise adjustment for the perfect response. The envelope follower output can be smoothed in either the attack, decay, or both stages simultaneously, enabling a wide range of responsive modulation shapes. If you're looking to get your system listening to itself or sounds from the outside world and turn that information into CV, the EF-1 from Wildsync will do so handily.
