Calling all Musicians, Mixing professionals and Mastering engineers, this app is for you! A/B audio comparison is the go-to audio tool to achieve the perfect mix or master and is now available on your favorite iOS device. A/B Audio is perfect for switching live between two mixes or masters so you can instantly hear the changes you made. Loudness match your files with the tap of a button (loudness matching is based on integrated LUFS) for a fair comparison. *Does this mix need more bass? *Compression ratio needs tweaking? *Too much reverb? *Too less reverb? *More limiting? *More chorus? *More of everything :)??? Use A/B Audio to blast your mixes anywhere and compare your mixes in as many places and situations as you can to achieve the best sounding mix/master for your track. Load tracks via the Music library (excluding DRM protected content), Drag and Drop on iPad or use your favorite file sharing app. After deciding which mix or master is the absolute best easily share the file from within the app and let your friends or fellow band members know which version you prefer. We even added a ' Blind test' option to let your ears decide which mix is the best one! ## Key features - Side-by-side audio mix comparison - Live switching between mixes - Load tracks from Music library - Support for iCloud Drive, Dropbox, Google Drive - Blind test option - Easy file sharing ## Chart rankings - #181 in Top Paid · Music (US App Store) ## Recent user reviews (10 of 15) All indexed reviews: https://appshunter.io/ios/app/ab-audio/id1312626953/reviews.md ### 5/5 — Smooth and easy to use *2025-03-17, version 2.9* Was at first hesitant to pay the price but the app works very smoothly and is not cluttered with anything unnecessary, helps me to hear differences clearly in my mixes! ### 5/5 — Perfect *2024-10-07, version 2.9* Simple, effective. Love that the tracks are already synced. Exactly what I was in need for. In the future, if you guys are planning to do updates, it would be nice to have a “Trim” to match levels when necessary or even an auto match. Thanks for the app. Really useful ### 5/5 — simple and perfect *2024-06-26* it's the kind of thing that when you need it, you need it, and this does it in a no-fuss, no feature bloat way ### 5/5 — Great and simple tool for A/B'ing *2024-02-06* Using in mixing/mastering environment, specially helpful when comparing mixes vs masters for clients. ### 4/5 — Excellent app- wish I could set the start time of each song individually. *2024-01-22* Simple interface. Perfect for what you’d want this tool to do. The only thing it needs is to be able to individually set the play back parameters of each song. If I’m comparing my mix with another song, I would like to be able to scrub to each chorus, for example, individually and compare, instead of having to compare 1:22 seconds at each file. I can see it would be useful to compare the same time too, if I’m A/B-ing versions of the same song. Maybe a toggle that allows you to turn on or off individual times? ### 4/5 — very useful *2024-01-21* a mono/stereo toggle would be great ### 5/5 — Exactly what it says and brilliantly *2022-07-07* I have been searching high and low (and spending major $) for an app like this since QuickTime 7! Elegantly implemented with a nice big volume slider this is perfect if you are comparing mixes or checking for mastering artifacts. Well Done!! ### 5/5 — Thumbs Up! *2022-06-08* Yodeling, thanks for your review. I have been looking for an app like this for years. I love how simple everything is. Love it! My only request would be some form of audio leveling between the two songs. Sometimes I’ll do a mix I don’t slam the limiter as much and when I switch back and forth, I want to hear it at the same volume. Maybe even a volume slider on each track? It’s this possible? Otherwise, this app is near perfect. ### 5/5 — Perfection *2022-04-28* Sometimes you wish you had a certain tool, do a google search, find exactly what you're looking for, buy it, use it, be impressed that it works exactly how you imagined, then come back and write a 5-star review for it. Thanks! ### 1/5 — Error messages on all music files *2021-08-01* I just purchased this app for iOS and receive the error message “import error: please check file integrity” on every audio file I’ve attempted to load so far. The files are all .wavs from my iCloud Drive and when I attempt to import from my music folder on the phone alternatively…nothing happens. I truly hope this is fixable as this app is something which would greatly improve my mastering workflow on the go. **Developer response:** Hi Myra, Please uninstall the app and install version 2.1 which has just been released. You will find that the issue has been fixed. Thanks for your feedback! ## Frequently asked questions about A/B Audio ### What is A/B Audio used for?
