AB Assist is designed to streamline the process of comparing multiple audio files quickly and effectively. Whether you are evaluating different takes, mix revisions, master versions, or plugin options, this tool provides a straightforward way to listen and assess your choices. It supports blind testing by randomly labeling channels in 'test' mode, helping to eliminate subjectivity and bias from your audio comparisons.

The latest version expands functionality by allowing users to compare up to four audio sources simultaneously, including stereo surround mixes with any number of channels. Features such as automatic short-term loudness matching (LUFS) ensure a balanced listening experience, while mono-check capabilities let you evaluate mono fold-downs with ease. Smooth fading between sources enhances seamless switching, and multiple plugin instances communicate directly for efficient workflow.

AB Assist offers compatibility with both Mac OS X 10.9 and Windows 7 systems, requiring minimal RAM to run smoothly. Its user-friendly interface and precise comparison tools make it a valuable asset for audio professionals seeking to make informed decisions during mixing and mastering stages.
