Wider -- derived from the massively popular stereo feature of its sibling Manipulator -- expands the stereo image of a mono signal to an awe-inspiring amount of width. However, Wider is a unique stereo plugin in the sense that it is completely “mono-compatible," meaning that any signal that has been extended will always remain in phase with itself, even if summed to mono. Many stereo effects currently in use have the nasty habit of knocking signals out of phase which can quickly make a track sound muddy and unbalanced, or make sounds seem flat and lacking dynamics if one isn’t mindful of the effect. Thanks to Wider’s one-of-a-kind all-pass and comb filtering algorithm, a natural-sounding stereo image is created from a mono channel without compromising the phase between the sides. Because Wider cancels itself out when summed to mono, the original signal is left intact. Wider can be used to increase the stereo image of any mono signal up to 200% of full stereo for an extra wide, exaggerated effect. ## Key features - Expands stereo image of mono signals - Completely mono-compatible - Maintains phase coherence - All-pass and comb filtering algorithm - Increases stereo image up to 200% ## Recent user reviews (10 of 24) All indexed reviews: https://appshunter.io/ios/app/wider-by-infected-mushroom/id1338262710/reviews.md ### 3/5 — Seems debatable *2025-09-16, version 1.0.1* Not sure or if it’s just me. But something seems lower quality when I use it. Even when I don’t add a ton of width. Sometimes it sounds thin and spread out instead of wide ### 5/5 — Great job *2025-07-08, version 1.0.1* This plug-in has so much depth to it and it is my number one go to for mastering it provides just that little bit of widening on the sound without putting mud in it, which is great for making your sound feel like it is all around you instead of just in front of you ### 5/5 — Secret gem? *2023-12-09, version 1.0.1* It's crazy to me that this only has 9 ratings. This whole time I thought Infected Mushroom was some big developer, but just got around to looking for more releases and this is all I find. Anyway, thanks for making this, I put it on like 90% of my stems. Super simple, clean sounding, and incredibly useful for getting a bigger sound. ### 5/5 — It has one job, and boy does it do it well *2023-11-21, version 1.0.1* It’s pretty simple. Make it wider. As all music producers should be wearing headphones, you’ll definitely notice a difference in audio as it flows through your ears. It’s simple, and easy to use. Great job! ### 5/5 — really great plug-in *2023-11-21, version 1.0.1* This is a good plug-in and is essential for the trap beats I make. I liked this so much, that I amadeus sure to get the computer version for my FL Studio! ### 5/5 — Keyboards come alive!! *2022-09-04, version 1.0.1* My favorite app to enhance keyboards in the mix. Pianos especially benefit from this app. ### 5/5 — Stereo Widener *2022-02-02, version 1.0.1* This is exactly what I needed, spot on !! ### 5/5 — Perfect *2021-12-24, version 1.0.1* I generally mix mid side combine this with the free stereo imager for my kick and bass to be mid. Then I throw this on all my instruments at various widths and when u sprinkle in the fab filter q3 to eq mid side life is sweet on the iPad ### 1/5 — no big sur compatibility *2021-11-01, version 1.0.1* FIX IT. ### 5/5 — Works Perfectly for Free *2021-07-01, version 1.0.1* I needed to widen the drums to give a more intimate, live feel to a track with guitar, bass and drums on GarageBand. This worked perfectly and is free. Couldn’t ask for more. With some Eventide reverbs, I’m finding I enjoy recording with the iPad more than with Logic on a Mac these days. Also tried Cubasis but it had all sorts of noise, bugs and latency, so I’d recommend just using GarageBand with a few nice plugins like this one if iOS recording is your cup of tea. ## Frequently asked questions about Wider by Infected Mushroom ### What does Wider do?
