When more than one microphone is used to record a sound source, phase or polarity issues can arise between the different tracks. This can be due to the distance between microphones or any other factor that causes the audio to reach one track before the other. Often this is almost imperceptible, but in many cases it can make the recording sound "thin" or "weak".

Aligner is an automatic phase and polarity alignment tool, designed to streamline the daily workflow of audio engineers.
