## What is Exciter?

Exciter AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the Exciter AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of Exciter AUv3 plug-in comes as In-App Purchase.

The Red Rock Sound Exciter will allow you to improve and enhance sonic quality of signal more naturally than with equalization. Unlike traditional EQ that just turns up the existing harmonics, Exciter generates additional harmonics, therefore there is no boost in the output signal level, this maintains a clear and balanced sound.

Control & Indicator Functions:

• IN meter — Input Signal Level indicator;
• LEVEL — control knob for the Level of the Input Signal;
• HARMONICS — this knob controls the amount of generated Harmonics;
• TIMBRE — sets the balance between Odd and Even harmonics;
• FREQ — sets the frequency of the high pass filter in the side chain prior to the harmonics generator. For example, with a setting of 6000 Hz all frequencies above 6000 Hz will have Harmonics generated by Exciter;
• HL meter — the Level meter for the Harmonics that are created;
• MIX — sets the amount of Exciter enhancement added to the original signal;
• LISTEN — allows you to listen to the Exciter process alone;
• OUTPUT meter — Output Signal Level indicator;
• Undo/Redo;
• A/B comparison;
• 2x/4x/8x Upsampling;
• Macro controllers;
• Built-in Gain Match;
• Scalable GUI.

To use Exciter as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — Exciter will appear in the list of Audio Unit extensions for effect plug-ins in the host app.

## Key features

- Harmonic generation for enhanced sonic quality

### 5/5 — Thanks for fixing the crashes

*2026-01-05*

This was such a gem, I’m so happy you guys fixed the glitches. Now I can use this bad boy once again efficiently. Cant wait for more apps from you guys.

### 5/5 — Funktioniert einwandfrei

*2025-11-25, version 2.5.0*

super gemacht. HQ modus hörbar.
Schön, dass einem die Wahl gelassen wird ob man HQ und Oversampling braucht, oder ob man den prozessor belasten will.
5 Sterne

### 5/5 — Yo!!

*2025-05-24*

I was looking for a great Auv3 exciter app for my iPhone, so I asked AI. They suggested “Exciter”. Little did I know I was going to be amazed by it, as well as impressed about all the other plugins you guys have. Holy smokes! 
You guys ROCK! 6 stars ⭐️⭐️⭐️⭐️⭐️

### 1/5 — BUGS, CRASHES, EVERYTIME

*2024-03-21*

Fixed the bugs that makes it crash everytime I use garageband please. I would like to shop with you guys but THIS is what’s stopping me.

### 5/5 — Nice apps!

*2022-10-14*

Add a little sparkle with this one! Sound great, easy to use, get them all! New synth kicks!

### 1/5 — This will not work on my IPad even though I purchased it

*2022-01-13*

This will not work on my IPad even though I purchased it.
Who can I contact to sort this out

**Developer response:** support@redrocksound.pro

### 5/5 — This is secret sauce

*2021-08-23*

I have an old 190 kbps mp3 of a vocal separated from a music track recorded off a 90’s tape cassette, so not much top end to speak of. I added this, made some slight adjustments, and I swear it sounds like a studio recording. I mean, your results may vary, but I sure miss this plugin when it’s disabled.

I can definitely recommend this for mellow audio that needs top end restored. Another must buy for me. I also really like their bass enhancer. NOT sponsored - I just love the sound.

### 4/5 — wirkt gut

*2021-08-18, version 1.0.3*

der Exciter funktioniert wirklich gut. Ohne komplizierte Einstellungen werden Oberwellen zum Produkt gemischt und machen das Ergebnis deutlich transparenter, ohne Teilbereiche im Frequenzbereich signifikant zu verändern. 
Er ist einfach zu benutzen und sehr wirksam und erzeugt Ergebnisse, die mit einer Entzerrer/kompressor Kombination deutlich schwieriger zu erreichen sind, von der aufwändigen Einstellung einer solchen Kombination ganz angesehen.
Nachteil … es gibt ihn nur für Garageband, mit all seinen Nachteilen. Vorschlag …. Logic Pro wäre wünschenswert.

### 4/5 — GarageBand crashes

*2021-05-01*

I own all your EQs. Love the sound I can produce with them, but they crash GArageBand quite a bit. There’s just a high pitched click and then I have to close and reload GarageBand every time. Would appreciate some help with this Dev.

### 4/5 — Simple and useful for improving audio

*2020-05-23*

Update: Thanks to the dev for quick reply about issues. After buying the full version of the app I was able to get it to work in Cubasis. Developer passed on info on how to use it as a plugin in Garage Band (Does not show in External input as you might expect.) Shows up in some DAWs and recorder apps and can connect by Audiobus 3 in many others.

As for the effect itself, it's very good for demudding audio and crisping up the highs without adding excessive treble. Operation is simpler than other exciter plugins, which is a big plus. 

As a standalone app, it doesn't do much other than let you modify audio from the mic. Can't process files files or save output.

**Developer response:** Hi.
You wrote “External Input” in GarageBand — do You mean Inter-App Audio (IAA) plug-ins list for input signal processing? “Exciter” doesn’t support IAA format since it was deprecated since iOS13, according to Apple iOS13 release notes: “Inter-App audio is deprecated. Use Audio Units for this functionality moving forward”.
