Stereo Designer is an easy to use multi-purpose stereo shaping tool for Audiobus and Inter-app Audio. Create unique wide stereo image, "stereoize" a mono sound source, apply mid/side processing, independent high and low pass filters per channel, and more. Process synths, drum machines and hundreds of other apps by connecting through Audiobus. Use Stereo Designer as an effect inside DAW apps such as Garageband, Auria, Cubasis, and AudioShare using Audiobus or Inter-app audio. Stereo Designer supports Core MIDI via the Camera Connection kit, USB MIDI interfaces, Virtual MIDI and WiFi connections. The MIDI Learn function lets you easily assign your MIDI controller's knobs and sliders to control Stereo Designer's effect parameters. Here's what users are saying: " With Stereo Designer, Christopher has created one of the most impressive/creative stereo enhancement processors I’ve ever had the pleasure to use. If there was a VST/AU version for the desktop then I’d buy it in a heartbeat…." - Music App Blog (www.musicappblog.com)  "Add depth to your sounds - This can help add a missing dimension to your music. Try running a synth or drum app through it. Use an audio interface to process guitars, hardware synths, or even a signal from your desktop DAW. It works really well with the developer’s other apps too. Great with Audiobus." - dmonterroso (AppStore review) Stereo Designer features two distinct modes: PERFORM and TWEAK. • PERFORM mode is focused around four XY touch pads. Touch to control LOW PASS, DELAY, PAN and OUTPUT gain independently for left and right channels. • TWEAK mode features large expressive sliders and additional effect parameters, allowing you to fine tune your sound. In addition to Audiobus and Inter-app Audio support, Stereo Designer can also process external instruments such as guitar, voice and synths by connecting a microphone or professional audio interface such as the Apogee Jam, ONE, or any iOS compatible USB audio interface. Guitarists can use our effects live by connecting the output of their audio interface to an amp.

Habe ein ipad 2 mit ios7 und habe auch nicht vor weiter upzudaten.. Leider lässt sich die app nun nicht mehr öffnen.. Bitte eine stabile version für ios13 zur verfügung stellen.. Immerhin mal dafür bezahlt.. Traurig sowas :( **Developer response:** Please consider trying the latest version of Swoopster released late April 2024, which is v1.3.6. This update fixes the stability problems that were occurring when running Swoopster and my other apps on the most recent versions of iOS. ### 4/5 — Useful *2019-03-23* Stumbled across this app and am very glad I did. Has brought new life to my field recordings with the ability to tweak the stereo field and more. The only drawback is that the app hasn’t been updated in sometime and occasionally come across a few stability bugs. Nothing that can’t be solved with a reboot of the app, but still, can be a little frustrating. It’s worth it and hope the developers keep giving it some attention, unlike other similar apps that simply disappear with a new iOS update. **Developer response:** Hi, you may consider updating to the latest version of Stereo Designer v1.3.6, released in late April 2024. This update fixes the stability problems that were occurring when running on newer versions of iOS. Also, what a great use case for Stereo Designer, manipulating field recordings! ### 4/5 — Good *2019-01-18* Good, but for 5 stars needs AUv3 support. ### 5/5 — Had to write a review for this magical app! *2016-10-13* Hearing your audio do these wonderful things in the stereo field, is inspiring and beautiful. Top effects! Top Guy! For extra magic get the iPhone version too, then you can have it on 2 separate tracks, even more stereo expansion. These apps are Greeeeeeeeeeeeate! King ### 5/5 — Effektapp *2016-09-30* Sehr gut gemachte, sinnvolle und gut klingende Effektapp. Und seit Audiobus 2 noch besser zu nutzen :) ### 5/5 — Change Your Perspective... *2016-05-20* Literally. A useful and reliable tool. ### 4/5 — Please add a feature to import songs from iTunes library! *2015-05-04* I have a bunch of Mono songs that I would love to make into D.E.S.s, but I can't. I want it for my personal use! ### 5/5 — Impressive, powerful, use discretion *2015-03-26* This app is amazing for the price. Simply amazing. You get many different tweakable flavors of stereo design with a little something for everybody. Works great as an IAA in Auria these days, and it's always been rock solid as an effect in Audiobus. Just remember, a little selective stereo widening goes a long way :) Easily worth 5 times the price. Get it now and spread the love! ### 5/5 — A great and useful effect/utility *2015-01-27* This is much more useful than you may realize if you dabble in music production on your iPad. Being able to visually have complete control of your stereo field and depth really adds a nice dimension to your mixing. Highly recommended ### 1/5 — Fehlkauf *2014-12-14* Für Musiker nicht zu empfehlen! ## Frequently asked questions about Stereo Designer ### What is Stereo Designer?
