Cut Through Recordings has released Convergence Free, a freeware multi-band compressor effect for VST, VST3, AU, LV2, and AAX plugin hosts on Windows, macOS, and Linux.
Convergence Free is a multi-band compressor based on the full version of Convergence ($45) with some limitations. The free demo version of the software can be used for an unlimited amount of time. It offers up to four bands (ten in the full version) and the compression display is disabled (it shows a Demo Mode overlay). Also, only up to 2X oversampling is available (up to 8X in the full version of the software). Other than these differences, the free and paid versions of Convergence are identical.See also: Best FREE Compressor VST Plugins
The plugin has all the features you’d expect to see in a multi-band compressor. Each frequency band comes with the Attack, Release, Threshold, Ratio, and Gain adjustments. The band range is adjusted by moving a horizontal slider placed on top of a real-time spectrum display. This method of range adjustment is quick and intuitive. Another workflow enhancement is the Global control panel which enables the user to quickly adjust a single parameter for all bands. For example, you could adjust the Threshold value on all active bands by moving a single control knob.
Unfortunately, the interface design isn’t the best. The control layout is fine, but the font size is a bit too small and the color contrast is too low. The interface isn’t unusable, but it could do with some design improvements. On a positive note, the spectrum display at the top of the interface is useful and well-implemented. Also, there’s a handy set of alignment controls in the lower-left corner of the UI. These are used to quickly set the relative width of the active frequency bands.
To use the free version of Convergence, simply download the demo version of the software from the product page linked below. No signup required and you also don’t need to activate the software. Convergence is compatible with 32-bit and 64-bit digital audio workstations on Windows, macOS, and Linux. Cut Through Recordings are offering several other freeware effects, including the Entropy crossover delay plugin which was previously featured on Bedroom Producers Blog.
