HoRNet MultiFreqs

MultiFreqs 1.1.5 is available, this update is free for owners of the plugin and includes:

  • Finally fixed various issues with Logic on Apple Silicon

Inspect and compare multiple tracks at once

HoRNet MultiFreqs is a spectrum analyser that provides two different kind of visualisation of the audio spectrum for up to 28 tracks together.

The first visualisation type is called “analog” and is inspired to an analog hardware spectrum analyser that is still found on the master of many recording studios even today, the second one is called “digital” and it’s our own take on the typical spectrum analyser based on the FFT (the standard math to transform an audio file into its spectrum components)

MultiFreqs GUI is completely resizable and it’s crisp and smooth on every display thanks to its hardware accelerated drawing.

Up to 28 tracks can be shown together and you can select which one you want to display, on VST3 and AAX host the plugin is able to read the track name, but you can easily change it just clicking on the name of the instance.

The plugin offer different integration times and ranges for the levels shown by the spectrum analyser, it also provides peak and average display features . MultiFreqs can display both the “mid” (or sum) part of a stereo signal and the “side” (or difference) to help you isolate problematic frequencies.

To find out problems between tracks even faster MultiFreqs also has a “conflict” button that shows only the part of the spectrum in common between all the enabled tracks.

Using a multi track spectrum analyser like HoRNet MultiFreqs allows you to check against frequency collision in different track (like the classic snare and kick combo or kick and bass) and help you get a more separated sounding mix and when the GUI is closed it uses almost no CPU so you can keep an instance of MultiFreqs in every track of your mix and open it when you need it.


We decided to not provide a demo for MultiFreqs because we don’t want to to cripple our product too much and limiting the capability of this plugin for a demo would mean to provide a bad testing experience.

For this reason we offer an instantaneous full refund within 15 days of your purchase if you buy MultiFreqs and you don’t like it

another happy purchase.

GS says:

Great tool per se, but why waste so much space below the spectrum. absolutely unnecessary. Please add a proper fullscreen/windowed mode so it becomes usable.

Great plugin!!!

The plugin itself is fantastic, outstanding concept & a so-close to excellent execution. The massive unused space beneath the actual spectrum analyzer is pretty atrocious UI design & does nothing but bloat up your screen with useless filler, with no information presented whatsoever on it. The function of the plugin combined with this crazy sale right now caused me to look past this amateur UI design flaw. If this is fixed it's a 10/10, but at the moment it's more like a 6/10 because of a dreadful user interface choice. I'm not sure what the thinking was here, but you can do better. We've seen it. If you can fix the UI I think we'd be looking at the standard for budget multitrack spectrum analysis. Really this is my only holdup with the plugin. It's a valid one however, our screens only have so much room… we can't afford to have it bloated up like this. In this day & age it's unacceptable UI. if this wasn't less than a couple bucks on sale, I wouldn't have given this plugin a chance over this design flaw alone. I know I'm not alone in this sentiment. Please consider updating this in the future…. in spite of this it is a good plugin, but it could be excellent.

Hans says:

It's a really great idea to do it this way. Efficient for many engineers, I suppose.
But for this type of plugin, that does not process audio, only analyze, it would be great to be available for improving legacy projects, that can only be recalled in 32bit mode.

Great plugin. Can I request a feature whereby one is able adjust the eq for the different tracks on the same plugin plugin? That would be great.

I love this kind of utilities plugin, very useful to analyze accordingly your mixes submix via visual… i wud give it 5 star, it just i think the GUI could be better logistically.. too much empty space under the graphic spectrum.. anyway, always love hornet plugins!

Robert Ryda says:

I love you Saverio/HornetPlugins for being productive and making good plugins!

This analyzer is cool, however I have an issue:
Makes my Pro Tools 2020.11 crash and quit, I dont yet know why, but by just having the plugin present in the session..

Also I have a suggestion: Please make a few user-customizeable tweaks for UI, such as hiding some portions of the UI to have a bigger frequency window, instead of having groups part of it resize altogether; Soloing the frequencies for sweeping in A/D mode would be useful if that is possible; Soloing M/S would be useful;

ahmed saleh says:

i am happy that i can get this product during the last sale
but i wish it can read the name of the track it will be more easier and killer plugin to save us a time for another mixing task instead of typing the name of the track manually
i`m using studio one 5.2 and it can`t catch the name in vst or vst 3 version please work on to solve that

ottimo plungin

Junkyard Sam says:

Wow. I thought I could handle frequency unmasking by ear only — but I tried this on a finished mix and the additional separation I was able to achieve increased clarity and reduced listening fatigue. Outstanding.

MultiFreqs is another Hornet classic.
