Helix Tuner vs Exciter
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Helix Tuner
This app offers a novel approach to instrument tuning by visualizing sound as an interference pattern. It avoids pitch detection, instead creating an optical illusion of motion that indicates sharpness or flatness, appearing stable when in tune. This method is highly resistant to background noise and harmonics, providing clear tuning information even in noisy environments.
- Visual interference pattern tuning
- No pitch detection
- Optical illusion of motion for tuning
- Stable visualization when in tune
- Resistant to background noise
- Useful in noisy environments

Helix Tuner is a completely new way to tune your instrument. Unlike all other tuning apps, it does not detect your pitch at all. Instead, it combines the sound coming into the microphone with the desired tuning pitch to create a beautiful interference pattern on the screen. The interaction between your sound and the reference pitch creates an optical illusion of motion when your note is sharp or flat, and it appears stable when you're in tune. If you are tired of digital tuners that jump around erratically, have slow or delayed response to changes in your tuning, or in general just don't give you good tuning information, then Helix Tuner is the one you are looking for. When you manually select the tuning note, as opposed to letting the app detect it automatically, Helix Tuner is extremely resistant to background noise and higher string harmonics that confuse other tuners, causing them to jump around to higher notes and give wrong tuning information. Because the visualization system naturally responds more clearly to sounds near the selected tuning pitch, it is useful even when other musicians are playing nearby.
Exciter
This audio effect plugin enhances the sonic quality of your music by generating new harmonics, offering a more natural sound than traditional EQ. It provides detailed control over harmonic generation and signal mixing, and can be used within compatible music production apps.
- Harmonic generation for enhanced sonic quality
- Control over odd/even harmonic balance
- Adjustable frequency for side chain filtering
- Mix control for blending processed and original signal
- Input and output signal level metering
- Undo/Redo functionality
- A/B comparison for sound design

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.
