Stacked LOCAL (purple) and REMOTE (orange) FFT analyzers — right-click to add band splits, drag the HP/LP and threshold handles.
Two tracks fighting for the same frequencies — kick and bass, vocal and guitar? Drop SpectralMediator on both and pair them. It's a multiband dynamics processor whose sidechain is the other track: set your bands with threshold and ratio, and inside each one only the frequencies that actually clash come down — bin by bin, both directions. You pair the two instances from a dropdown — no sidechain bus to wire.
Stacked LOCAL (purple) and REMOTE (orange) FFT analyzers — right-click to add band splits, drag the HP/LP and threshold handles.
A multiband dynamics processor — split the spectrum into bands, set threshold and ratio per band. The twist: the sidechain is a paired track, it works both directions at once, and the reduction follows that track's spectrum frequency by frequency, not one amount per band.
By hand you'd need dozens of narrow dynamic-EQ bands, each sidechained, on both tracks. SpectralMediator gives you that resolution in one pairing — automatic, both ways, set from a dropdown instead of a sidechain bus.
Insert SpectralMediator on two masking tracks (kick + bass here) and pair them via the REMOTE dropdown. Each instance writes its FFT spectrum into shared memory and reads its partner's. Wherever the partner is louder than a band's threshold, this instance ducks just those bins.

Full functionality in demo mode — audio is briefly muted every 60 seconds with a smooth fade so you can fully evaluate the plugin before purchasing. No sign-up required.
The Windows installer is not code-signed, so SmartScreen may say the publisher is unknown, and a brand-new installer occasionally trips an antivirus heuristic. Neither is a detection — it is a reputation score that every unsigned release starts from zero.
C:\Program Files\Common Files\VST3\
and
C:\Program Files\Common Files\CLAP\
Nothing to do. Since v1.3.0 the disk image, the installer and all three plugin bundles are signed with an Apple Developer ID and notarized by Apple, with the ticket stapled into the files so it works offline. The publisher shows as Tony Cuny — the legal name behind Xeni Audio, which is what Apple puts on the certificate. Logic loads the AU with no workaround.
Summer sale — 50% off until July 20th (normally €29). One license, all formats, all platforms, forever.
