Some more updates for Polarity-SC: Output Gain Fix, Smoothing, Custom Curves & Frequency Guides. 💪Polarity Spectral Compressor has been updated with practical workflow improvements for dynamic spectral shaping across Windows, macOS, and Linux. The revised version fixes output gain behavior when using the mix control, making parallel processing and loudness matching more reliable in real-world compression and spectral balancing tasks.
New additions include spectral smoothing to reduce harsh bin-by-bin gain reduction, frequency guides for faster visual targeting, and editable curve points for custom dynamic EQ-style compression and gating. These changes make the free plugin more precise for controlling problem areas, shaping tonal balance, and experimenting with upward or downward spectral dynamics.
Key Takeaways #
The output gain behavior was fixed so gain compensation now works properly with the Mix control; users can apply gain reduction, enable Match to align input/output loudness, and then blend dry and wet signals without the dry path being incorrectly affected.
Match automatically compensates loudness by matching the output signal to the input signal, making A/B comparison and wet/dry balancing easier after compression.
A new Smoothing control reduces harshness caused by heavy gain reduction on individual spectral bins by grouping multiple bins together instead of processing each bin too sharply.
Smoothing applies to both downward and upward compression modes, helping make aggressive spectral processing sound less brittle in the high end.
The frequency display now includes visual guides at reference points such as 30 Hz, 100 Hz, and 1 kHz, making it easier to identify where processing is happening in the spectrum.
The graph now supports editable control points: clicking adds dots to draw custom spectral gain-reduction curves, allowing targeted dynamic processing in specific frequency areas, similar to a spectral EQ.
Right-click removes control points, and the custom curve can be combined with Delta mode and Slope settings for effects such as spectral gating or frequency-weighted dynamic shaping.
Current limitation: there is one shared curve for both upward and downward compression; separate custom curves for each mode are not implemented yet.
