Quick comparison tool - remove subjectivity and biases
AB Assist is a tool for quickly comparing multiple pieces of audio. This could be different takes, mix revisions, versions of a master, plug-in options, or something else entirely! Blind tests can be conducted in 'test' mode, with the channels labelled randomly in order to remove any subjectivity or biases.
