Powerful, no-fuss phase correction

Phase issues are the bane of any post-production audio engineer’s existence (they cause ulcers, migraines, and more here at Sweetwater). But multi-microphone recordings, and the resultant phase complications they can produce, are par for the course in film work. And oftentimes, the mics are moving around, causing comb filtering and other unwanted artifacts. But now Sound Radix’s Auto-Align Post plug-in is here, and it makes short work of these pesky problems. Auto-Align Post corrects for distances of up to 112 feet or a delay of ±100ms. Performing continuous phase/time correction for moving actors or cameras is no problem, courtesy of this plug-in’s Dynamic mode, and stationary microphones are even easier to fix, thanks to its Static mode. Best of all, everything is automatic — no manual adjustments are required!

What the pros are saying about Sound Radix’s Auto-Align Post:

  • “It’s helped me in my workflow to give me options — it’s very satisfying to do just two clicks and have everything in sync. I don’t have to zoom into the waveform level, futz it around, and make sure that the waveforms are in sync. It just works.” — Justin WalkerThe Dub Stage, Los Angeles
  • “I deliberately created a piece of content to try it out where I set up a fixed boom mic, put a personal radio mic on myself, and then walked around in a reverberant space. When I came to play it back, it was like, ‘wow’.” — Mike ThorntonProduction Expert Editor, London
