Luna Co. Audio has launched 4K EQ, MultiComp, and Tape Machine, three free mixing instruments for Home windows, macOS, and Linux.
At first look, I figured these have been easy mixing utilities we’ve lined dozens, if not lots of, of occasions: an equalizer, a multi-band compressor, and a tape-style saturation plugin.
However after going by the characteristic lists and documentation, I sort of realized that Luna Co. Audio aimed larger than “primary freeware.” All three plugins are very thoughtfully designed, extraordinarily well-documented, and polished in a approach that’s on par with business software program (and fortunately, that is one thing I’m more and more seeing from unbiased builders).
And once I say polished on par with business software program, I’m referring to the deal with strong DSP and options that transcend the fundamentals. The one factor that these don’t supply is flashy hardware-like interfaces that you just’d discover in most paid plugins.
Let’s shortly undergo all three plugins.
4K EQ
4K EQ is a console-inspired equalizer modeled after traditional British desk designs. It gives two modes that mirror the conduct of various console eras, with broader, extra musical curves on one aspect and tighter, extra surgical conduct on the opposite.
Alongside the same old 4 EQ bands, you get high-pass and low-pass filters, non-compulsory saturation, oversampling, mid/aspect processing, and a real-time spectrum analyzer.
It’s not probably the most superior free EQ on the market, nevertheless it’s versatile sufficient for many channel work, and in addition works properly on buses when used gently.
MultiComp
MultiComp is probably the most versatile of the trio by way of workflow. It combines a number of traditional compression kinds right into a single plugin, together with optical and FET-style compression, VCA and bus compression, a clear digital mode, and a completely featured multiband choice.
What I liked, although, is how clearly the manufacturing unit presets are defined on the product web page. As a substitute of simply providing you with “Vocal” or “Drum Bus” presets, the descriptions clarify why sure assault and launch occasions have been chosen.
So when you’re nonetheless studying the fundamentals of compression, MultiComp is definitely a helpful studying software as a result of you possibly can undergo the presets and work out precisely what the settings are and why.
Tape Machine
Tape Machine is probably the most formidable plugin right here. Simply by way of flexibility, that is one thing you’d usually discover in a premium tape emulation plugin.
It’s a extremely detailed tape emulation with a number of machine fashions, tape formulations, tape speeds, and sign paths. You may dial in refined saturation for combine bus duties or push issues towards lo-fi territory utilizing wow, flutter, noise, and bias controls.
There are additionally stereo VU meters, oversampling choices, and a wide variety of presets that showcase each clear and character-heavy settings. Once more, it’s surprisingly near what you’d anticipate from a paid business tape plugin, though ChowTape is one other very robust contender in that regard..
I haven’t had time to check these plugins in depth but, however primarily based on my first impressions, this can be a launch it is best to positively take a look at. One other massive plus is you could obtain all the things instantly from the developer’s web site with out creating an account or registering.
All three plugins can be found for Home windows, macOS, and Linux in VST3 format, with AU help on macOS and LV2 help on Linux.
