The FAC fx never disappoint and can always find a place in my mix. ### 5/5 — Aural Lushness *2022-11-01* A beautifully crafted shimmer verb from Fred. Adds some wonderful ambiences you your productions. Thanks Fred ### 5/5 — The best *2022-10-26, version 2.3.3* This is the best!!! ### 5/5 — The best reverb I ever had *2022-06-09* I only wish the encoders would rotate slower, so that I could make fine adjustments a little bit easier. Apart from that: This is hands down the best reverb I ever had. And I had quite some. You can easily set it up for beautiful wide open spaces, and this is what it is being advertised for most prominently. But to my surprise, I like it as well for short drum rooms. Alteza just sounds EXTRAORDINARY GOOD! ### 5/5 — VERY NICE! I LIKE! *2022-05-23* Very lush and spacey sounding. Using on AUv3 instruments as well on hardware synths and it never disappoints. Good night Much Love ### 5/5 — Incredible ambiance space *2022-05-18* This is just what I was looking for, in an ambient reverb. Beautiful dreamy spaces, for my synthesizers. Good interface allows me to get what I want, with ease. Incredible presets. I suggest adjusting dry/reverb mix to taste, and saving, as many presets are a bit wet to start with. Really glad I found this. ### 5/5 — Excellent *2022-05-15* Lush and organic. Amazed something of this quality is available on iOS. App is stable, reliable with a well designed interface. All of the FAC apps are extraordinary and professional. ### 5/5 — Gorgeous Reverb *2022-04-19* Everything FAC does is amazing. I highly recommend all of his apps. This reverb is a perfect example. All his stuff is a great mix of form and function. It can be super lush and atmospheric, or tight, and wobbly. There is a lot of potential sounds to be made with this effect. Two pitch shifters, with +-12 semitones add to the fullness of the sound. My go to reverb. Definite 5 stars. ### 5/5 — Absolute MUST HAVE for ambient guitarists! *2021-05-15* This app is a MUST HAVE if you play ambient guitar! It is truly stunning to play through it and the presets with certainly keep you busy for hours. ### 5/5 — Love it *2021-02-24* Hands down one of the most precious app of my virtual gear! ### 5/5 — Believe Every Review! *2021-02-18* This is really that good! Just listen to the reviews and understand that yes (against all your attempts to believe otherwise), it really does sound that freaking amazing!!! This is the way... ### 5/5 — Ambient goodness *2021-01-24* This is the most astounding effect available for creating lush ambient pads. Simply feed in almost any sound and listen to the sound transform and morph into something reminiscent of a movie soundtrack. As with all of Fred’s apps, this is top quality and is a standard that all other developers should aspire too. ### 5/5 — The best! *2020-12-30* I love the shimmering effects!!! ### 5/5 — Really? *2020-12-23* I don’t understand the point of this App. All it does is make everything I push through it sound absolutely breathtakingly gorgeous. ### 5/5 — Great developer / Amazing Apps *2020-08-16, version 1.2* It's effects like this that make hours go by like minutes and music production a real treat on the iPhone. Don't sleep on these - every FAC effect is a gem. Be sure to check this guy's YouTube channel out as well - he goes way beyond tutorials and shows unique ways to use his remarkable products. ### 5/5 — BEST SHIMMER *2020-08-07* This is really best shimmer and reverb in the appstore, for sure ## Most critical reviews (10 lowest-rated) ### 1/5 — Wot *2020-02-21* I don’t know why so many people have given it a good review it doesn’t even freeze properly in Cubasis . It takes A few seconds to speed up it just sound like a cutdown version of Black hole **Developer response:** Update: Mixdown in Cubasis is solved in Version 1.1 Please update, and reconsider your rate/review again. Best, Fred 21/02/2020 Dear, please contact me via social media. I will help you to solve your issue in Cubasis. It s very pitty that you did not contact me first. I devote a lot of attention to the user satisfaction. Best, Fred ### 3/5 — All the effects sound over the top *2026-06-21* I’m not sure if I’m doing something wrong but all the effects sound way too extreme. I just want a gentle reverb and everything is crazy! Would love it if the presets were toned down a lot more ### 3/5 — Not working on 2021 iPad *2022-01-08* Sounds great using it as host on iPhone but cannot get it processing audio as host on iPad. Just sits there. It does work if hosted by other app like beatmaker3. **Developer response:** Thank you for your message, the standalone app should not be used. Please check the first line of the description "This is an AuV3 fx". You have to use FAC Alteza as an AUv3 in AUM, BM... If I understand properly, you reported an issue with the standalone app only on the last iPad. It will be fixed, but please use and enjoy the AUv3 and update your rate and review regarding your AUv3 experience. Do not hesitate to contact me, Fred ### 4/5 — Good sound, confusing interface *2022-02-16* Monomaker is too confusing, stages are cryptic ### 5/5 — <3 *2025-11-23, version 2.4.3* Such a magical reverb! ### 5/5 — Pure space✨ *2025-11-03* FAC Alteza has been part of my recent sound work — I love how it opens up space in such a deep and emotional way. The shimmer feels organic, never artificial, and the interface is so intuitive that it invites instant creativity. Perfect for creating wide, dreamlike soundscapes, even for beginners. ### 5/5 — Perfect on iPhone *2025-06-16* A big and great thanks to the developer, because great sound is one thing but usage on the iPhone another story. The whole package of apps have a great sound and the AUM user interface changes if you are on iPad or iPhone. Perfect usability on iPhone! ### 5/5 — i want… *2025-01-27* …a hardware baby! By far my favourite reverb! ### 5/5 — Amazing! *2024-11-28, version 2.4.3* Great shimmering harmonic reverb with great tone! ### 5/5 — My go-to reverb *2024-02-24* I use a few different reverbs on the iOS platform, and must say FAC Alteza is the one that I reach for the most during my sessions. It is extremely versatile, and instantly adds life and atmosphere to any sound that you feed into it. It can give that otherworldly quality to the soundscape, in a similar way that an Eventide Blackhole does, but in a way that is entirely unique and unmistakable. It can turn a simple monophonic sound source into an expansive space of complex harmonic richness. ## Most praised reviews (4 highest-rated) ### 5/5 — Excelente *2023-11-12, version 2.4.3* 100% recomendable ### 5/5 — Fantastic *2023-08-20* One of my favorite reverbs ever. Every FAC app would be an asset to your iOS production toolbag 💪🏾 ### 5/5 — Ecstasy *2023-07-06* It's only the most beautiful reverb in the universe...and there is nothing else like it. Pure audio love! ### 5/5 — Best reverb for ios *2023-04-21* As an ambient producer, this reverb is essential for lush and dreamy reverbs. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
