Antelope Audio A4-1B Perpetual Plugin License + 1 year SC Native

The Antelope Audio A4-1B plugin faithfully brings the warm, smooth tone of vintage analog compression into your digital workflow. Modeled after the revered A4-1B Analog Opto Valve Compressor, this plugin replicates every detail of the original's tube circuitry and custom transformers to deliver unmistakable analog warmth and dynamic character. Whether you're enhancing vocals, tightening a bassline, or gluing a mix together, the A4-1B offers the signature sound of classic optical compression with the flexibility of modern digital control.

Designed for professional producers and engineers, the A4-1B integrates seamlessly with your favorite DAW using VST3, AU, or AAX formats. Real-time automation of critical parameters like Attack, Release, Gain, and Threshold allows for dynamic mix shaping. Advanced features such as high-pass, low-pass, and band-pass sidechain filtering, along with a precise de-esser mode, make it a versatile tool for a wide range of audio tasks-from transparent vocal leveling to deep tonal sculpting.

This perpetual license ensures lifetime access to the plugin, and it also includes a one-year Synergy Core Native membership, giving you additional access to premium plugins from Antelope's acclaimed effects suite.
