Requirements According to License Type
UPG (upgrade) license: requires a previous eligible "AB Assist" license from the same publisher. Proof of ownership (serial number/customer account) may be required during activation.
What NUGEN AB Assist 2 Is For
AB Assist 2 is designed to impartially compare multiple versions of the same audio content. It is aimed at sound engineers, mixers, producers, and mastering studios who evaluate alternative takes, mix revisions, plug-in processing, or final masters, in stereo as well as multichannel formats for post-production.
Main Features
Instant Multi-Source Comparison
Switching between four sources is done with one click, featuring smooth crossfades to avoid interruptions. Different instances of the plug-in synchronize automatically, eliminating any external routing.
Fair Listening and Objective Decisions
The auto-level-match aligns short-term levels according to LUFS to compare content, not volume. The "mono-check" instantly verifies mono compatibility, useful for broadcast and restrictive platforms.
Unbiased A/B/X Testing
The "test" mode shuffles and anonymizes channels to perform true blind evaluations and confirm your mixing, mastering, or sound design choices.
Ready for Stereo and Surround
Whether it's a musical stereo mix or multichannel mixing for film, TV, or games, AB Assist 2 handles comparisons regardless of the number of channels.
