Ring Modulator vs Elyfino
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Ring Modulator
This app creates unique metallic and bell-like timbres by multiplying two audio signals. It offers three modes for versatile sound design, from internal oscillators to sidechaining external audio.
- Ring modulation effect
- Dual input capability
- Three distinct modes (OSC+OSC, INPUT+OSC, INPUT+SIDECHAIN)
- Mono and stereo input support
- Adjustable carrier and modulator frequencies
- Mix and output gain controls

Ring modulation multiplies two signals together sample by sample. The result contains the sum and difference of their frequencies, the sidebands, while the original carrier and modulator tones are suppressed. This produces the metallic, bell-like, and clangorous inharmonic timbres associated with classic ring modulators, from robot voices to detuned percussion. Signal path: the carrier is multiplied by the modulator to form the wet signal, Mix blends that against the dry carrier, and Output applies a final makeup gain. Ring Modulator is usable in three modes and can take either mono or stereo inputs. The host app must support mixing to bus inputs or sidechaining in order to use Ring Modulator with dual input. Outputs mono signal. OSC + OSC Both carrier and modulator are internal sine oscillators, set by Car Freq and Mod Freq. Produces classic two-tone ring modulation with no input required, good for bell tones and metallic drones. INPUT + OSC The carrier is your track's audio and the modulator is the internal sine at Mod Freq. This is the standard ring-mod effect: it turns voices and instruments metallic or robotic and adds inharmonic sidebands. This is the default mode. INPUT + SIDECHAIN The carrier is the main input and the modulator is a second, independent input routed into the plugin's sidechain bus. Use it to ring-modulate one track by another, for example a vocal shaped by a drum loop or synth pad. This requires a host that supports sidechain routing; if nothing is routed to the sidechain, the input passes through dry. Car Freq and Mod Freq do not apply in this mode.
Elyfino
This audio effect plugin enhances low-end frequencies for producers and sound designers. It generates controlled subharmonics, adds optional fuzz for grit, and offers flexible tone shaping and wet/dry blending. Achieve larger-than-life bass and drums without sacrificing clarity.
- Source-tracked subharmonic generation
- Program-dependent compression
- Optional fuzz for harmonic edge
- Split-band tone shaping
- Wet/dry blend control
- MIDI learn and control
- Factory and user presets

Some low-end tools are static. Elyfino listens! Feed it a bass line, 808, kick, synth, guitar, drum bus, or cinematic hit, and it builds movement from the source. Make the low end feel larger without losing control. Elyfino is a real-time AUv3 effect for producers, beatmakers, mixers, and sound designers who need controlled low-end and harmonic edge. It combines program-dependent compression, source-tracked subharmonics, fuzz (optional), split-band tone shaping, wet/dry blend, calibrated output, factory presets, user presets, and MIDI control in one focused processor. Key features: - Source-tracked subharmonic generation for bass, 808s, kicks, toms, synths, guitars, impacts, and post sound design. - Comp, Subharmonics, Sub Mix, Sub Focus, and Sub Detect controls for tuning depth, punch, tracking sensitivity, and sustain. - Clean Path routing for low-end reinforcement without fuzz. - Powerful Fuzz for growl, translation, density, and harmonic edge when the sound needs more bite. - Tone, Mix, and Output controls for color, parallel blend, and level-matched gain staging. - 25 factory presets covering Utility, Bass, Sub Design, Drums, Guitar, Synth, Post, and Parallel workflows. - User presets with iCloud-backed sync for keeping custom sounds available across devices signed into iCloud. - MIDI learn, manual CC assignment, default CC mapping, and optional MIDI broadcast for hardware and host control. - Standalone version with Audio Settings, CoreMIDI input routing, and a built-in manual for setup and reference. - Mono and stereo AUv3 effect operation with supported 44.1, 48, and 96 kHz sample rates. Use Elyfino subtly to reinforce fundamentals, harder to make bass and drums shake the earth, or in parallel when you want controlled weight under the original performance.
