This week's featured free plug-in from our free plug-ins database is Convergence From Cut Through Recordings, a plug-in which represents one of the most under-represented categories of free plug-ins - Multi-band compressors.
To be clear, the free version Is a demo with some features disabled. However, the missing features aren’t deal-breakers but we wanted you to be aware that this is the case.
What Is Convergence?
The free version of Convergence is a multi-band compressor that offers up to 4 bands of compression (the full version offers up to 10). The crossover frequency can be set for each band and controls are linked by default but can be unlinked.
It features a useful input vs output history for each view, which makes it visually informative. The transfer curve is disabled but still seems to work while greyed out. Be aware that it’s quite easy to generate distortion, the time constants are unlabelled and sound fast to me. Take care when setting it up!

The Compressors
Convergence uses crossover filters with -6dB gain at the crossover frequency that sum together to create a perfectly flat frequency response. These -6dB crossovers also introduce the least amount of phase shift possible while still being low on CPU usage. The compressors are designed to have a digital feel to their attack and release timing to be as precise as possible.
The Displays
Convergence comes with several displays that are fine-tuned to help you visualize what effect your tweaks have on the incoming audio. The main display is a spectral analyzer with controls to adjust the crossovers for each band. This allows you to easily dial in the frequencies based on which frequencies are most prominent. Each band also has an envelope display, a compression display, and a gain reduction display. The envelope display helps give you an idea of how the attack and release times will affect the compression. The compressor display shows how the threshold and ratio controls will affect the compression as well by graphing input versus output levels. Finally, the gain reduction display shows input levels and output levels over time so that you can easily see transients and how they are being affected by the compressor.
Soloable Bands
One of the most useful features of Convergence is the ability to solo bands. You can simply hold down the Control key and left-click a band to solo it to really dial the compressor settings. Multiple bands can be soloed simultaneously.
Free Version
This plug-in is also available as a free version, which works exactly the same as the full version except that it is limited to 2-4 bands rather than the 2-10 that the full version boasts. The other limitations of the free version are that oversample is only available up to 2x and the compression display is disabled. Try it out now to see the power of this compressor for yourself!
