Harmonic Exciter is an AUv3 Compatible plugin for your favourite DAW such as Cubasis, Auria, AUM, Meteor, BM3 or GarageBand etc. The main purpose of a Harmonic Exciter is to help instruments cut through a mix and give some edge and clarity to a sound by adding additional harmonics. It can even be used to simulate valve / transister based saturation or overdriven harmonic distortion. How it works: Every sound under the sun can be constructed by a series of sine waves, the root sine wave denotes the fundamental percieved frequency or the series of waves. By adding additional harmonics which are simply multiples of the fundamental frequency you can turn say a simple sine wave into a square or sawtooth wave. For those who know anything about synthesis you will know these complex waves pack more punch and brightness for the same volume level. So by adding additional harmonics we can lift a sound and make it appear louder, brighter and stand our in our mix. It can also be used to saturate say a bass frequency range boosting bass without needing additional EQ which simple boosts existing harmonics and oftern requires compression to keep under control. This makes the harmonic exciter a great tool for that perfect mix and a nifty trick audio engineers have been using for decades. In Practice: The 4Pockets Harmonic Exciter allows you to visually see the incoming audio spectrum broken down into frequency bands so that you can immediately see any deficiencies in the mix. You can select a frequency range (whether bass, mid, high or even say a kick drum) and use the 10 harmonic sliders to dynamically synthesize of additional harmonics and phase manipulation. Generally it's the 'odd' harmonics that effect a mix in a more melodic way (1st, 3rd, 5th etc.), while even harmonics (2nd, 4th, 6th etc.) tend to be a little discordant or can be used to mimmic distortion of valve amps etc. When adding saturation in this way you can create simulate pleasing overdriven valve/transistor type amplification (transistor amps generally only apply odd harmonics). Why is a Harmonic Exciter better than EQ: While you can boost EQ using a Graphic or Parametric EQ, this only boosts existing harmonics which soon requires compression to avoid clipping. The Harmonic Exciter changes the tonal content of a sound to saturate without adding the same boost in volume. The result is more punch and an ability to cut through the mix without levels getting out of control. You can often get a more natural and aurally pleasing saturation from this kind of effect than using a dedicated oversdrive effects. If your DAW supports MIDI based effects you can also control certain features via CC controllers or using the pitch bend and mod wheel (or CC's 20, 21 and 22 to control the exciter window, gain and size). ## Key features - Adds clarity and edge to audio - Synthesizes additional harmonics - Simulates valve/transistor saturation - Visualizes incoming audio spectrum - Adjustable harmonic sliders - Phase manipulation ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/harmonic-exciter-auv3-plugin/id1458704222/reviews.md ### 1/5 — Poor *2020-08-19* App does not work. Makes no real change. ### 1/5 — Crash *2020-02-18, version 1.02* Admittedly downloaded to an iPad 2 but said the iOS was supported? Just crashes every time on the title screen so no idea what the apps like when it works. Also tried the app support link and took me to a random site. Can any of this be rectified or could I have a refund? ### 4/5 — An interesting addition *2019-04-27, version 1.02* Got lots of this devs apps, and this one is just a polished as the rest. Works best on individual instrument tracks used with a light touch, as opposed to a complete mix, which tends toward becoming a sonic trifle. Oh, and always make sure you have ‘Enable’ switched on. Nic ### 5/5 — Fine Tune Sound Textures *2019-04-21* The app enables you to bring out specific sounds you want to be able to hear in a very precise way. An excellent addition to the sonic shaping toolbox. ### 2/5 — Just OK *2019-04-20, version 1.01* I’ve got some of this devs other apps, which are mainly good but there is the odd decidedly average one, too. This one is below average, at least for me, because the effect it has on the sound is minimal at best and non-existent more than half the time. And, yes, I do know where the ‘enable’ button is! I’ll stick with it in the hope of a developer update, though, because the concept is a good one. Edit: thanks for your response, Paul. I did watch the videos, yeah. Thanks for the the changes you've implemented. I do really love some of your other apps, too. Shimmer is an instant classic 👍 ### 5/5 — It works *2019-04-10, version 1.0* You’ve gotta press enable button ## Frequently asked questions about Harmonic Exciter AUv3 Plugin ### What is Harmonic Exciter AUv3 Plugin used for? Harmonic Exciter AUv3 Plugin is used to add clarity, edge, and saturation to audio by synthesizing additional harmonics. It helps instruments cut through a mix and can simulate valve or transistor-based distortion. ### How does Harmonic Exciter AUv3 Plugin work? It works by adding multiples of the fundamental frequency (harmonics) to a sound. This process can make a sound appear brighter and punchier, similar to how synthesis creates complex waveforms from simple ones. ### Is Harmonic Exciter AUv3 Plugin better than EQ? Yes, it can be. While EQ boosts existing harmonics and may require compression, Harmonic Exciter changes the tonal content to saturate without a significant volume boost, leading to more natural saturation and better mix control. ### What DAWs are compatible with Harmonic Exciter AUv3 Plugin? It is compatible with DAWs that support AUv3 plugins, such as Cubasis, Auria, AUM, Meteor, BM3, and GarageBand. ### Can Harmonic Exciter AUv3 Plugin be controlled via MIDI? Yes, if your DAW supports MIDI-based effects, you can control certain features using CC controllers, pitch bend, and mod wheel, or specific CCs for window, gain, and size. ### What is the price of Harmonic Exciter AUv3 Plugin? Harmonic Exciter AUv3 Plugin is available for a one-time purchase of $8.99. ### How often is Harmonic Exciter AUv3 Plugin updated? The latest version is 1.03, and the app was last updated on September 4, 2025. Updates typically occur to improve performance and add features. ### Does Harmonic Exciter AUv3 Plugin have ads?

Added dedicated buttons for the scope and graphic display modes. Saves the graphical modes as part of the saved state. ### 1.0 — 2019-04-09 No release notes. ## Apps similar to Harmonic Exciter AUv3 Plugin | App | Rating | Price | Category | | --- | --- | --- | --- | | [TB Sibalance](https://appshunter.io/ios/app/tb-sibalance/id1593744258) | 3.4 (9) | $7.99 | Music | | [Addictive Pro](https://appshunter.io/ios/app/addictive-pro/id1130398188) | 4.7 (18) | $5.99 | Music | | [Warm Distortion](https://appshunter.io/ios/app/warm-distortion/id1221368957) | 1.0 (1) | $1.99 | Music | | [Transient Shaper](https://appshunter.io/ios/app/transient-shaper/id1599434645) | 5.0 (2) | $5.99 | Music | | [TB Enhancer](https://appshunter.io/ios/app/tb-enhancer/id1484449791) | 4.6 (18) | $6.99 | Music | | [True Pan](https://appshunter.io/ios/app/true-pan/id6444190718) | 5.0 (7) | $4.99 | Music | ## More apps by 4Pockets.com - [Meteor Multitrack Recorder](https://appshunter.io/ios/app/meteor-multitrack-recorder/id417726727) - [Tone Generator Ultra](https://appshunter.io/ios/app/tone-generator-ultra/id514273546) - [PocketRTA Ultra](https://appshunter.io/ios/app/pocketrta-ultra/id514903914) - [StompBox Band](https://appshunter.io/ios/app/stompbox-band/id845046209) - [Audio Toolbox](https://appshunter.io/ios/app/audio-toolbox/id1353387223) - [Audio Compressor AUv3 Plugin](https://appshunter.io/ios/app/audio-compressor-auv3-plugin/id1426387457) All apps by 4Pockets.com: https://appshunter.io/developer/370131860 ## Related topics [harmonic exciter auv3 plugin](https://appshunter.io/ios/topics/harmonic-exciter-auv3-plugin) · [exciter](https://appshunter.io/ios/topics/exciter) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
