AB Assist 2 from NuGen Audio is a quick comparison tool that allows you to compare multiple pieces of audio. This version is an upgrade from owners of version 1 that introduces several significant improvements. Version 2 allows you to compare four audio sources, and you can now compare surround mixes in any channel count, whereas version 1 only allows for stereo mix comparison. AB Assist 2 is Windows and macOS compatible and works with DAWs that support AAX, AU, and VST3 protocols in 64-bit.
