PHA-979 is useful during mixing sessions, especially when working with audio material recorded by a number of microphones. In many cases, this allows you to solve various synchronization problems arising from the microphone placement chosen during tracking session. In other cases, this process can help align drums and other instruments each other, which leads to coherence between accuracy and time not attainable by ordinary single time alignment.
In addition to the phase change, PHA-979 features positive and negative delay while eliminating the need to move events on the track in the sequencer to align the time on any set of recorded tracks. PHA-979 also provides controls balance and roll mid / side channels that let you record pairs of stereo microphones in a single stereo track without resorting to dual recording mono (on separate tracks) which usually takes a long time in an edition later.
