AB Mix Check

Compare your mix against references quickly on headphones with loudness-matched A/B playback, markers, notes, and fully on-device processing.

AB Mix Check helps you compare your mix against reference tracks quickly on iPhone, especially when you are checking on AirPods and headphones. Import common audio file types like WAV, MP3, and M4A, switch instantly between Mix and Reference while keeping context, and use loudness matching to reduce level bias. Add markers and notes during checks, then export your findings back to your workflow. Everything runs on-device.
