About A/B Audio

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!
