The Best Exciter Plugins Around

There’s a lot of plugins claiming to be ‘one of the best exciter plugins around,’ but let’s be honest, that’s just not true. I’m here break down the actual best options out there. The following best exciter plugins (the elite 8) all bring serious harmonics, excitement, and professional-grade effect all day, so let’s get into it.

#1. Bloom by Oeksound

Bloom by Oeksound isn’t just one of the best exciter plugins out right now; it’s probably the most intelligent-sounding one I’ve used, no joke.

What makes this exciter plugin special is how it reacts to incoming frequency content in real-time, so you’re not just boosting highs blindly… 

You’re shaping harmonics that move with your tracks. 

It’s constantly analyzing your signal, reacting to transients, tonal balance, and even subtle dynamic shifts (meaning the effect you get is always musical and always responsive, like it should be).

It has parameters for you to play around with, like Bias, which lets you push Bloom to favor either fast transients or more sustained signals.

Turning it up to +100 adds more detail to things like vocals, while bringing it down to -100 gives you a smoother result across mid-range material. 

Bloom also includes a Sensitivity control, which helps you fine-tune exactly how aggressively the algorithm tracks incoming changes.

Lower settings result in a more consistent enhancement, while higher settings give you a livelier, more reactive effect.

The Focus knob works like a frequency tilt EQ.

Dial it left to highlight low-end texture, or right to bring out air and brightness, depending on what you’re working on and the vibe you’re going for, of course. 

You can also solo the focus band, which makes it easier to hear exactly what frequency range you’re affecting.

This is a super helpful feature when you’re working fast and don’t want to second-guess your ears, so I definitely recommend messing around with that as well.

Drive goes from 0 to 100, and once you hit anything above 65, you’ll start hearing clear saturation buildup and harmonic lift without the harsh edge you tend to get with some analog emulations. 

The harmonics it introduces are dynamically shaped too.

So, you’ll notice that on quiet passages, it holds back, but on louder, more active moments, it subtly steps forward.

There’s also an Air control for adding that modern shimmer 一 just boosting it 20–30% on vocal stacks gives everything that extra sparkle and clarity. 

And if you’re running Bloom on an instrument group, it’s smart enough to stay transparent while still enhancing the tone, which is honestly rare.

Bottom line, this exciter plugin feels like it’s reading your mind, and once you hear how it adapts to each track, it’s hard to go back to anything static.

#2. Waves Aphex Vintage Aural Exciter

If you’re looking for that old-school shimmer that instantly makes your tracks sound more expensive, the Waves Aphex Vintage Aural Exciter seriously delivers. 

This epic exciter plugin is modeled after the OG Aphex hardware from the ‘70s (and yes, it still holds up).

It’s crazy how just blending in 10-20% of this thing on a vocal or drum bus gives the sound that polished, high-end air that feels like it was printed to tape.

You’ve got three modes to work with:

• AX
• Mix1
• Mix2

AX is more subtle and works great on a send if you want to blend it in slowly with your dry signal. 

Mix1 and Mix2 are for direct inserts and have slightly different harmonics 一 with Mix2 being a little more hyped in the mid and top-end.

Personally, I love it for parallel processing on bass or synth tracks. 

The AX Mix knob is where the magic happens, though… I usually keep it around 15–25% on vocals to bring out clarity and excitement without making it harsh. 

And if you want to go full vintage, just flip the Analog switch on and let that subtle tube-style noise creep in.

It’s lowkey amazing on instruments that need a little character.

Just remember to be careful with the input and output gain because there’s a +18dB range, and if you push it too hard, you’ll end up over-saturating everything.

But dialed in right, this exciter plugin can totally change the tone of your mix. 

I wouldn’t say it’s the flashiest of the best exciter plugins, but it’s certainly one of the most efficient when you’re looking for that classic, musical lift.

#3. Arturia Bus EXCITER-104

I wasn’t expecting to like the Arturia Bus EXCITER-104 as much as I do, but this thing seriously surprised me (in a good way).

It’s split into two sections, and both give you a ton of control: 

1. One for low-end
2. One for top-end excitement

Also, the Big Bass module is a beast on kicks and subs. 

If you set the Drive around 60% and widen the stereo field just a touch, you can add this crazy-wide yet tight low-end that doesn’t cloud up the mix.

On the flip side, the Exciter section shines on things like vocals, drums, and even full mix buses. 

It’s even got its own tone and saturation controls, and when I crank the Excite knob to about 40% and adjust the focus range between 4–8kHz, it adds this sweet upper-air lift without sounding brittle. 

You also get these handy solo buttons for each module so you can quickly hear what each part is doing in isolation, which makes dialing in the right balance super simple.

Another thing that’s worth mentioning is the Quality Mode toggle.

Switching from Studio to Render mode ups the processing fidelity, which is clutch when bouncing stems or mastering. 

Arturia threw in 20+ starting-point presets as well, which are actually usable 一 I tried the “Punchy Kick” one and only had to tweak one knob before it worked perfectly.

Out of all the best exciter plugins I’ve tested lately, this one’s easily the most modern-feeling and I definitely recommend it. 

It’s clean, versatile, and it gives you full frequency-focused control without making you overthink every little move.

#4. Waves Vitamin Sonic Enhancer

Vitamin is one of those exciter plugins that somehow feels like a saturator, a multiband EQ, and a parallel process or all rolled into one. 

If you’ve got dull tracks that need life (but a standard exciter isn’t cutting it) this one’s a go-to, for sure, and it’s one of Waves plugins, so you know you’re getting quality.

It splits your signal into five separate bands (Sub, Low, Low-Mid, High-Mid, High), and each one has its own Drive, Punch, and stereo width control. 

Being able to solo each band while you dial in harmonics is something I really love because it’s perfect for detailed mix tweaks.

The Drive knob on each band can go up to +18dB, which lets you really push the harmonics where you need them.

Especially on low frequencies where traditional exciters tend to fall apart. 

For example, pushing the Low-Mid band to around 10dB adds a thick, warm layer to bass and drums that actually sits in the mix instead of stomping all over it. 

Then we have the Punch control that tightens the transients, almost like light compression 一 great for when you’re working on mid-range instruments like guitars or snares that need a little smack achieved.

Also, and this is a big deal, you can blend the wet/dry signal for each band.

That kind of parallel processing control isn’t super common in exciter plugins, and it’s what makes Vitamin feel more like a mastering tool than just an enhancer. 

I usually keep the Sub and Low bands a little more subtle (30–40%) and push the High-Mid a bit more when working on vocals or synth leads. 

And if you’re finishing a master, this exciter plugin can literally save a dull bounce.

All-in-all, it’s one of the best exciter plugins if you want multiband precision and surgical tone shaping without losing that musical feel. 

Just be careful because it’s easy to go overboard, especially on the high end.

#5. Slate Digital Fresh Air

If you want instant brightness and sparkle without doing a ton of tweaking, Fresh Air by Slate Digital is ridiculously good. 

It only has two knobs (Mid Air and High Air), but honestly that’s all you need. 

I was skeptical at first, but the more I use it, the more I realize how smartly it’s tuned. 

Mid Air hypes everything in the upper midrange, which is great for adding life to vocals, snares, or anything that’s sitting in that 2–6kHz zone. 

High Air targets that top shelf (10kHz and up) and it’s amazing for drum overheads or, like a mastering engineer, getting that flat bounce sound.

Even though it looks simple, this exciter plugin is doing a bunch of stuff under the hood, and it’s not just EQ, it’s all about adding: 

• Extra harmonics
• Dynamic saturation
• Tube-style excitement

But all in a way that reacts to the signal rather than just blasting fixed frequencies. 

I usually keep the High Air around 30–35% and Mid Air around 20% when I’m working on vocal tracks 一 enough to lift the clarity, but still subtle enough to avoid sibilance. 

And the built-in Trim control lets you pull back the output if things start peaking, which helps maintain proper gain structure.

Fresh Air really shines when you’re stacking it on a bus, like a vocal or drum group, and then sending that through a little bit of tape or compression. 

That way, you’re getting that upper harmonic excitement but still locking everything into the mix. And the fact that it’s free for Slate All Access users just makes it even better.

If I’m being honest, it might be one of the best exciter plugins for producers who want fast results without digging through endless menus. 

It’s clean, musical, and surprisingly hard to mess up, unless you max out both knobs (so don’t do that). But used right, it can completely change how your tracks feel.

#6. PROCCESS.AUDIO Sugar

Sugar is one of those exciter plugins that makes everything feel instantly finished. 

It was designed by real engineers who clearly got tired of using 5 different devices just to add harmonics, clarity, and tone to a mix. 

If you’ve got something that sounds a little flat (like a drum bus that just doesn’t punch, or a vocal that’s missing that lift), it can seriously bring it back to life.

At the heart of it are four bands, each with two flavors you can switch between: 

• Low
• Mid
• High
• Air

For example, on the Low band, you can toggle between “Thick” and “Punch.”

Thick gives you a warm, subby bump that works amazing on bass, and Punch tightens everything for more mid-forward presence. 

On the Air band, “Shine” boosts around 16kHz and up, which gives your tracks that clean, modern sparkle without feeling harsh. 

I usually set the Air level between 25–40% depending on how dense the mix is because any higher and it can start sounding overly hyped.

The parallel processing blend knob is super useful as well. 

You can add all your enhancements and then back them off to taste, which helps you keep things subtle when needed. 

And once you’ve dialed in your effect, listening for perfection, the Warmth section lets you add full saturation to glue everything together.

It leans into tube-like harmonic content and can be pushed all the way up to +24dB. 

The built-in level matching button is also a nice touch, so you’re not being tricked into thinking louder always sounds better.

Simply put, Sugar feels like it was developed with the modern mastering engineer in mind, but I tend to use it on individual instruments too.

It’s perfect for when you’re looking for fast, clean excitement with a bit of tone-shaping baked in and definitely deserves the crown of one of the best exciter plugins around.

#7. SPL Vitalizer MK2-T

The SPL Vitalizer MK2-T is a bit of a different beast, but once you get the hang of it, it’s one of the most powerful exciter plugins you can throw on a mix. 

It’s based on analog tube circuitry, so everything it does is colored in that smooth, classy way that people really react to (even if they don’t know why).

It doesn’t just add harmonics 一 it reshapes your frequency response in a way that helps things sit better, especially in busy mixes.

The Bass knob isn’t just boosting lows; it introduces phase-shifting that tightens the low-end and adds punch without feeling boomy. 

I usually set it around 4–5 (on the scale of 0–10) for kicks or 3 for vocals. 

The Mid-Hi Tune lets you sweep from 1kHz all the way to 22kHz, and this is where you dial in the “Vitalization” part to boost clarity/excitement in a specific frequency zone. 

The Process knob controls how intense the exciter effect is, and you can push it up to 10 if you really want things to sound like it’s jumping out.

Personally, I tend to keep it around 4–6 to stay subtle, but it’s dealer’s choice.

You also get Stereo Width control which I find very intriguing as it can make your tracks feel wider without pushing the mix off-center. 

And then there’s the Soft Saturation knob, which brings in gentle tube-style warmth.

It’s super nice on mastering chains where you want to add character without changing the balance. 

And finally, you’ve got the output gain for keeping everything on point after you’re done dialing it in and feel like it’s up to par.

I won’t lie, the interface takes a little time to get used to…

But, once you understand what each section is doing, this legendary exciter plugin can totally transform flat mixes into polished, radio-ready material any day.

It’s not the newest tool in the shed, but trust me it still earns a spot on any list of the best exciter plugins, and for good reason.

#8. Klevgrand Knorr

And last but not least, let’s talk about Klevgrand Knorr, because this exciter plugin does something a lot of other enhancers don’t even try to touch…

It focuses purely on low-end harmonic reinforcement (bass and kick elements specifically). 

If your 808s or subs feel a little too smooth or flat in the mix, Knorr gives them that extra grit and tone without needing to over-compress, distort, or layer a bunch of other stuff.

Here’s what makes it special: it uses a technique called synchronous modulation, which basically tracks the pitch of your input in real time and adds harmonics that lock to it.

This means it stays musical, no matter what material you feed it. 

The Harmonics Amount knob goes from 0 to 100, and for subtle movement, I’ll usually keep it around 20–30. 

If you’re going for more excitement, feel free to push it up toward 50–60, just don’t overdo it because that’s where things get a little messy. 

The Tone knob lets you shift where those harmonics sit, and I’ve found it’s most effective when it’s focused just below the middle of the spectrum.

You’ve also got a Dry/Wet Blend slider that makes parallel processing a breeze. 

For example, I like setting it at around 60% wet for basslines that need to cut through without crowding the low frequencies of the kick. 

This exciter plugin, unlike some other enhancers/models, also includes real-time visualization, which helps you see what you’re doing.

But more importantly, you can actually hear the difference clearly as you make changes. 

The best part in my opinion is it reacts to playing dynamics, so it doesn’t just slap on a static effect 一 it breathes with the signal, which gives it a more analog, reactive sound.

I didn’t really expect to learn this much from such a simple interface, but Knorr really delivers a sense of precision and purpose. Every knob does something meaningful. 

If you’re into layering heavy 808s or want your kick to feel like it’s been run through an old-school rack unit, this thing adds that vintage weight in a clean, modern way. 

NOTE: It doesn’t just affect bass. Sometimes I’ll throw it on low vocal layers or even drum loops just to create some thickness underneath, so you can get creative.

Knorr may not be your traditional exciter plugin because it’s more niche, but if your tracks are lacking punch in the low-end, and you want something that adds just the right effect, this belongs in your chain. 

Out of all the best exciter plugins, this one fills a space that most others totally miss. 

It’s not flashy, but when you need harmonics down low that feel intentional (not just noise), this is the one to reach for.
