Wavesfactory is one of those boutique developers that manages to feel both playful and serious at the same time. Founded in Spain, they’ve built a reputation for VST plugins and Kontakt libraries that mix technical precision with a bit of character.
Their catalog balances two worlds: plugins that handle mixing, tone-shaping, and color, and Kontakt libraries that bring unique instruments. This guide pulls the best of both. We’ll look at Wavesfactory’s standout plugins, their libraries, and where they fit in your workflow. Let’s start.
Best Wavesfactory Plugins
Here’s where we break down the best plugins Wavesfactory has to offer. From problem-solvers that clean up a mix in seconds to character pieces that add vibe, this list highlights the standouts worth your attention.
| Plugin | Type | Score |
| Trackspacer | Dynamic spectral ducking for mix clarity | 4.7/5 ⭐ |
| Spectre | Harmonic enhancer and parallel EQ | 4.8/5 ⭐ |
| Equlaizer | Intelligent auto-balancing EQ | 4.7/5 ⭐ |
| Echo Cat | Vintage-style tape echo with modern control | 4.7/5 ⭐ |
| Cassette | Nostalgic tape coloration and lo-fi vibe | 4.8/5 ⭐ |
| SK10 | Subkick simulation for added low end | 4.5/5 ⭐ |
Now let’s break down the best Wavesfactory plugins, including what each one does best and how they actually feel in use when you drop them into a session.
Trackspacer
Traditional sidechain compression reacts to volume. Trackspacer reacts to frequencies. It analyzes the sidechain signal in 32 bands and carves out only the parts of the spectrum that clash.
That means your vocals can sit perfectly against guitars without thinning them out entirely, or a kick can live comfortably alongside a bass without constant EQ moves.
It’s like having an assistant engineer riding dozens of tiny faders in real time. Subtle or obvious, it’s always clean and musical-and once you’ve used it, you’ll wonder how you managed without it.
Spectre
Boosting highs with a regular EQ often makes things harsh. Spectre solves that by injecting harmonic content, not just gain. You set a band and pick from 10 saturation styles (tube, tape, diode, bit, digital clipper, and more.)
Because it’s parallel, the original signal stays intact, and you’re layering color on top rather than destroying balance. On vocals, Spectre can add silky air; on bass, extra presence that cuts through small speakers. On a master bus, it glues a mix together in ways traditional EQ just can’t.
Equalizer
When ears get tired, EQ tweaks feel like guesswork. Equalizer offers a shortcut: it listens across 32 bands and automatically adjusts each one toward a balanced target level. That can mean smoothing harsh mids, pulling down boomy lows, or brightening dull highs-all with minimal effort.
You can run it in one-knob mode for fast results or go deeper with per-band adjustments, tilt controls, attack and release settings, and mid/side options.
Because it runs with zero latency, it’s also a solid choice for live engineers who need instant clarity on the fly. It’s less about reshaping tone and more about keeping everything under control.
Echo Cat
The Watkins Copicat defined an era of tape echo, and Echo Cat nails that tone while adding modern control. You still get the lush, slightly unpredictable repeats, but now with tempo sync, per-head adjustments, stereo widening, filters in the feedback loop, and even ducking so the echoes don’t step on your main signal.
Push the input for gritty saturation or max the sustain for self-oscillating textures that become instruments in themselves. Whether you want vintage slapback, psychedelic swirls, or subtle width, Echo Cat delivers all the charm of tape without the maintenance headaches.
Cassette
There’s nothing clinical about Cassette. It models the quirks of four classic tape types and all the side-effects that came with them: hiss, wow and flutter, saturation, compression, and uneven stereo balance.
Instead of sounding like a “lo-fi filter,” it genuinely feels like you tracked through an old deck. Producers lean on it to make sterile synths warmer, to glue background vocals, or to give a beat that raw demo energy.
Push it hard and it gets gritty; use it lightly and it just adds subtle movement that makes things feel alive. It’s a character piece that works in more mixes than you’d expect.
SK10
Not every useful plugin has to cost money. SK10 is Wavesfactory’s free tool that emulates a subkick mic, adding natural weight to drums without muddy EQ boosts.
Drop it on a kick drum track, and suddenly you feel that sub energy in your chest. Try it on toms, and they sound like they were recorded with bigger shells. For a freebie, it’s one of those “why not have it” tools. It’s fast, effective, and capable of fixing one of the most common mix struggles: weak low end.
Best Wavesfactory Libraries for Kontakt
So we’ve already seen why Wavesfactory has earned a solid reputation for its plugins – but their Kontakt libraries deserve just as much attention. These libraries are designed to be playable, flexible, and inspiring in both production and scoring.
| Library | Role | Score |
| Mercury | Grand piano | 4.6/5 ⭐ |
| Guzheng | Ancient Chinese plucked zither | 4.2/5 ⭐ |
| Demonic Virtuoso | Authentic harpsichord library | 4.6/5 ⭐ |
| Marxophone | Quirky fretless zither / dulcimer vibe | 4.7/5 ⭐ |
| Strum Guitar | Realistic guitar strums (4 instruments) | 4.3/5 ⭐ |
| Ukulele Collection | Strummed + fingered ukulele library | 4.3/5 ⭐ |
Now let’s break down each library.
Mercury Piano
Mercury isn’t just another piano library. It was sampled from Freddie Mercury’s personal Fazioli F-228 at Metropolis Studios, and that history comes through in the sound.
With 5 mic positions, multiple pedal techniques, sympathetic resonance, and more, it can be intimate one moment and thunderous the next. Play softly and it feels cinematic and emotional; hit harder and it gets punchy enough for pop or rock.
For many producers, it becomes their go-to piano library for Kontakt because it balances character with versatility.
Guzheng
The Guzheng is a Chinese plucked zither with a rich, bending tone. Wavesfactory went beyond standard sampling, capturing finger, pick, stick, bow, and even e-bow articulations.
That means you can use it traditionally for authentic Asian textures, or push it into ambient drones and hybrid scoring. With effects built in and plenty of round robins and velocity layers, it feels alive rather than mechanical. Whether you’re producing cinematic cues or adding unique flavor to electronic tracks, Guzheng brings something that most Western libraries can’t.
Demonic Virtuoso
Harpsichords often sound thin or brittle in sample form, but Demonic Virtuoso avoids that trap. Recorded with 3 mic positions (close, mid, far) and full round robin sampling, it delivers the bright, percussive pluck you expect, but with depth and presence that makes it sit in modern mixes.
You can play authentic Baroque pieces, sure-but it also layers beautifully under strings, works in film scores, or even adds a sharp edge to experimental electronic arrangements. The included effects let you take it from historical to contemporary in seconds.
Marxophone
The Marxophone is one of those instruments that makes people ask, “what is that sound?” Part zither, part dulcimer, it has a metallic, bouncing timbre thanks to its spring-activated hammers.
Wavesfactory captured multiple articulations chords, springs, picks, and fingers so you can go from folky strums to tremolo textures that shimmer.
It’s perfect for indie film scores, folk-inspired arrangements, or even just adding a subtle texture that cuts through dense mixes. Out of all their libraries, this one leans most into playful character.
Strum Guitar
Programming believable guitar strums is one of the hardest things to fake. Strum Guitar makes it painless by sampling real upstrokes and downstrokes across four instruments: acoustic, 12-string acoustic, electric, and 12-string electric.
The built-in chord recognition and sequencer let you play natural progressions with timing variations that feel human, not quantized. For quick demos it’s a lifesaver, but with the right processing, it can also hold its own in finished productions. It’s not meant to replace a session guitarist-but when you need convincing strums fast, it delivers.
Ukulele Collection
There’s a reason why Ukulele keeps showing up in ad work and jingles: it nails that upbeat, happy sound without hassle. The Ukulele Collection covers strummed and fingered articulations, recognizes extended chords (7ths, add9s, etc.), and even includes a stereo “doubler” for instant width.
With multiple velocity layers and round robins, it avoids the mechanical feel that plagues many ukulele libraries. Whether you’re writing a cheerful commercial, a kids’ show theme, or just want to lighten the mood of a track, it’s a fast, reliable tool.
Conclusion
Wavesfactory keeps its catalog focused: plugins that solve mix problems fast and libraries that feel authentic and playable. Instead of quantity, they deliver tools that consistently earn a place in sessions.
Frequently Asked Questions
Is Trackspacer really different from sidechain compression?
Yes. A compressor ducks overall volume, but Trackspacer ducks only the frequencies that overlap. It’s like precision sidechain that saves you from over-compressing.
Can Spectre replace an exciter?
It goes further. Spectre acts as a parallel EQ with multiple saturation styles, so instead of just “brightening,” it adds harmonic color across specific ranges with more control.
Do I need full Kontakt for these libraries?
For some, yes. Mercury Piano is compatible with the free Kontakt Player. The others (Guzheng, Demonic Virtuoso, Marxophone, Strum Guitar, Ukulele Collection) require the full version of Kontakt.
Which library is the most versatile?
If you only grab one, Mercury Piano covers the widest range-from intimate solo pieces to aggressive pop chords. But if you want something unique for cinematic or hybrid work, Guzheng and Marxophone are hard to beat.
Are the plugins heavy on CPU?
No. Wavesfactory designs with efficiency in mind. Even heavier processes like Spectre’s oversampling run well on modern systems, and lighter tools like SK10 are virtually instant.
Is SK10 really worth installing if it’s free?
Absolutely. It’s one of the quickest ways to add low-end punch to kicks and toms without EQ mud. It’s so light on CPU that there’s no downside to keeping it in your kit.
