HoRNet MasterTool is a sound processor designed to apply that final touch to your tracks, you can think of it as a mastering robot.

Thanks to our algorithms and some clever intelligence built in the plugin can adapt to almost every music genre, if you are searching for an easy way to fix your tracks and make them sound good MasterTool it’s here to help you, and if you are a podcaster or work with voiceovers, we have also added some special algorithm tweaks to make you happy.

The plugin takes care of fixing frequency spectrum issues in your mix thanks to our frequency unmasking algorithm, then analyzes the dynamic content and using our coherence meter algorithm as feedback it sets a clipper and two different limiters.
The first clipper and the first limiter cut off the peaks increasing the loudness, the second limiter helps in reaching the final level you specify.

Old Price: 22,99€

I trust this brand, i don't even try the demo. I Just buy.

Tim says:

Excellent Plugin, However, A wet/dry mix knob would be well appreciated. Also, the plugin glitches when adjusting the paramenters in real-time. Also, suggest that a video should accompany every new plugin release as I am certain that this will help sales. Also, A LITTLE PRICY FOR HORNET AS THERE ARE SIMILAR PLUGINS THAT CAN ACCOMPLISH THE SAME RESULTS.

Its will teach me to always test a demo before buying. I performed 3 tests and the plugin crashed the session. I have no other problem with my machine. I am running windows 10 with an I7 9gen and 32GB of 3200MHz ram and 250 / 1TB SSD. My sound card is a thunderbolt Antelope. Maybe there will be updates that will be corrected. For the moment the plugin has not ruined me but it is unusable.

Just purchased this today and this is the best plugin ever!!! It's better than Izotope and these mastering online services!!! Great job once again!!!

Jens says:

Tried the demo and no matter which DAW I use, the plugin crashes the session. Everything else on my computer works flawlessly. Windows 10, Intel Core i5 8250U, 24GB Ram, 1TB SSD. Hope this will be resolved as I'm very curious about this plugin.

Robert Thornton says:

Not experienced any crashes to date, only issue is the real -time adjustment freeze-up…hoping for a update/fix to resolve…apart from that it's working great!!

I'm a bit disappointed because MasterTool doesn't work at all with Reaper (i own many others hornet plugins which perfectly work and that i like).
On my main PC (i7 win10 64bit 16Go Ram) it freezes Reaper when i want to delete the plugin and when i launch then stop the learn button, i can see that it updates indefinitely but doesn’t do anything, eq, limiter are freezed.
On my second machine (win10 64bit i5 8Go ram) MasterTool isn't recognized at all (vst and vst3).
And no answer to the tickets i open to the support (one of them is opened since 11 months). That's why i'm writing here
