Auto-Align is an automatic microphone time alignment plug-in.
Time-aligning a multi-microphone setup is crucial to achieve coherent and punchier sound. When recording an instrument with more then one mic, sound tends to reach each microphone at a slightly different time and thus cause some frequencies to cancel each-other while other frequencies can build-up unnaturally.
Auto-Align will "listen" to your multi-mic recording and will automatically measure and compensate for the delay between the microphones - sample accurate.
When distant microphones are used and a delay is desired to preserve a sense of space, Auto-Align can time-place the microphones to better match the close-mic'ed source.
