Frequently Asked Questions

Soren is a standalone desktop app designed for precise audio mastering. It performs billions of operations for each master to ensure top-tier quality. Soren is not a DAW plugin — its advanced AI model requires non-realtime processing.
Mix Agent is new in v1.5. It analyzes your mix before mastering and detects common issues like tonal imbalance, resonances, and low-end problems. You can apply deterministic fixes with adjustable intensity, then use the result as your mastering input.
No. Soren processes everything locally on your device, ensuring complete privacy. After the initial online activation, no internet connection is required.
Soren and real-time plugins (like Ozone) work fundamentally differently. Soren processes the entire audio file by dividing it into thousands of segments and applying billions of non-realtime calculations. It follows a specialized AI-driven model that can only function offline, ensuring automated yet track-customized mastering. Real-time plugins operate as effect chains for manual adjustments — great for hands-on workflows, but limited by real-time constraints.
Yes, you can try the demo version here.
No. Soren offers a one-time perpetual license, allowing you to master unlimited tracks. Just choose the license type that fits your needs — Standard or Business.
macOS 12 or higher (native Apple Silicon or Intel) and Windows 10/11. We recommend minimum 8GB RAM. v1.5 can process files up to 90 minutes on Apple Silicon M1 with 16GB RAM — 3x more than the previous version.
We're actively working on batch processing, additional Smart References, and expanded Mix Agent capabilities. We value your feedback — reach out anytime.
