RM-1 Wave Modulator RM-1 is a multi purpose audio effect designed around various types of modulation. Featuring a built-in carrier oscillator, multimode filter, envelope follower and low frequency oscillator, RM-1 creates new sounds by combining carrier waveform and the audio input in different ways. Types of modulation: - Ring Modulation (virtual analog) - Ring Modulation (digital) - Amplitude Modulation - Phase Modulation (DX-style FM) - Frequency Modulation (linear) Overview: - Built-in carrier oscillator with variable wave-shape (sine->square) - Built-in multimode Filter (LP, HP, BP) - Built-in Envelope Follower and LFO Connectivity: - Standalone (MIC, USB audio) - IAA / Audiobus - AUv3 Plugin ## Key features - Multiple modulation types (Ring, AM, FM, Phase) - Built-in carrier oscillator - Multimode filter (LP, HP, BP) - Envelope follower and LFO - Standalone and IAA/Audiobus support - AUv3 plugin compatibility ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/rm-1-wave-modulator/id1436855751/reviews.md ### 1/5 — Never worked(s) *2024-08-24, version 1.1* Thought I had Ring, FM, Am+ together got a little hum inside a host and 0 strait out my I-pad. Contacted the people but I did not even get a Response. Thanks for nothing. Though I have most of your other apps and they work, this is an expensive one(for ios) and the one that stands out in ios apps(if it actually worked). Looks it works for some other lucky humans? ### 5/5 — Best Ring Modulator App in Existence! *2020-01-06, version 1.0.1* I’ve been looking for a perfect ring modulator app for well over a year, and my dad came across this app recently. This app is absolutely perfect in every way and it is so relieving to have an app that accomplishes as much as some high end guitar gear! (I’d also like to mention the real reason why I bought this app, I needed it to make voices for a Dalek from Doctor Who, and it absolutely delivers!) I couldn’t be more pleased with this app, it is well worth everything and you won’t be disappointed if you’ve been looking for a Ring Modulator! A+++ ### 5/5 — Passive diode ring mod *2019-09-19* It sounds like a passive diode ring modulator in some settings! Capable of much more than just ring modulation. It's so good, that I wish it was available for the iPhone. ### 1/5 — AUv3 Totally broken in NanoStudio 2 *2019-02-28* Seems like a really cool effect, but the audio unit is totally broken, won’t even load the UI ### 5/5 — Everything I could want for this variety of app *2019-01-28, version 1.0.1* This app has a great, well laid out GUI, sounds great, and explains it functions in a clear, accessible way. In the time I spent with it, I’ve found that everything functions as it should. It’s even an audio unit, which is a must for me! 5 stars. Thanks for bringing a ring modulator to the iOS music making environment. ### 4/5 — Way cooler than normal *2018-12-22, version 1.0.1* This effect suite is more intricate and amazing than most other ring mods for sure. The filters are ace and this thing rocks on bass, just need some creativity and experimenting and the results can be sweet yet nuts. ## Frequently asked questions about RM ### What types of modulation does RM-1 Wave Modulator offer?
