Painless Audio Comparison — from Mono to Immersive Mixes!

This article was Written By

Our Product Research Team

Get to know them!

With NUGEN Audio’s AB Assist 2, you can painlessly compare audio from up to four distinct sources — compared to the 2-source limit of its predecessor — to streamline your workflow. Whether you’re revising full mixes, adjusting individual takes, or reviewing masters, AB Assist 2 eliminates the frustration of bouncing between multiple projects and plug-ins, saving time with seamless integration into your setup. Useful comparison tools work to extract subjectivity and bias from your review process, like the “test” mode, allowing for blind tests by randomly labeling incoming audio tracks. To put it differently: it helps you get out of your own head. Sweetwater production pros are quick to herald AB Assist 2’s comprehensive mix accommodations — it is capable of comparing mono, stereo, and even surround mixes with any channel count. Additionally, the automatic level-matching instantly matches the LUFS of your sources, while the Delta function will play only the difference between your sources to pinpoint struggle points in the process. You can also use AB Assist 2 for monophonic downfolding to painlessly perform mono checks. If this all weren’t impressive enough, the multiple, simultaneous instances of the plug-in that you can run will communicate directly with one another, which means no added hassle with an external send.

Note: This is a specially priced version of AB Assist 2, from NUGEN Audio, available to select users. Please contact your Sales Engineer with any questions or concerns regarding qualification.

These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
