Softube Flow Mastering Suite review
A focused mastering suite for macro-driven chains, references, and detailed metering.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Softube Flow Mastering Suite is a mastering plug-in environment for music producers and audio engineers. Its central workflow uses engineer-designed signal-chain Flows, with macro controls that adjust multiple plug-in parameters together. Users can also create customizable chains and User Signal Chains. The suite runs on macOS and Windows and supports VST, VST3, AU, and AAX formats, making it suited to producers and engineers who want mastering tools inside a DAW.
Pricing is subscription-based in the listed US pricing, at 14.99 USD per month, with regional currency variation. The Flow Mastering Suite plan includes the Flow Mastering Suite plug-in, professionally designed Flows, more than 20 mastering plug-ins, monthly credits toward perpetual plug-in ownership, and Flow Credit Store Plus access. A 14-day free trial is available. The plan structure is straightforward, but the monthly credits and credit-store access are important parts of the purchasing model for buyers comparing it with individual plug-ins.
The standout feature is the macro-driven approach: one control can shape several plug-in parameters within a Flow, while custom chains preserve room for more detailed work. Visualizations cover frequency, stereo image, gain reduction, loudness, and dynamic range, with LUFS and True Peak metering for level assessment. Reference tracks can be compared through the sidechain input, and low-latency processing is available. Separate included plug-ins can be loaded in a DAW, so Flow Mastering Suite fits users who want both guided chains and individual processing options. It is a good choice for macro-led mastering workflows; buyers seeking a free tool or broader production software should look elsewhere.
