Burbank, CA (December 20, 2021)―While working on his personal music writing and recording projects and mixing and production work for top television networks, Grammy Award-winning audio mixer Justin Merrill has begun using Nugen Audio plug-ins.

Merrill utilizes Nugen Audio’s Halo Upmix and Halo Downmix software and the ISL limiter on a regular basis. He also uses the brand’s VisLM loudness meter as needed, and is currently diving into Paragon, Nugen’s latest offering.

He typically works on audio for a variety of reality programs, in addition to remixing network intros―updating them from stereo 5.1 to 7.1 surround—and turns to Nugen’s Halo Upmix software to add space to the audio. “Halo Upmix is the one that I definitely use the most and, compared to any of the other upmixers I’ve seen, Nugen’s is the most versatile,” Merrill says.

“A lot of other plug-ins are very basic—you put something in, and you get something else out, whereas with Nugen, you can tell it which channels you actually want and move stuff around. It’s definitely more useful than any other ones I’ve used, and I think it just sounds better than the other solutions, by far. It’s usually the first thing I go to if I ever get a mono or stereo file that I want to spread out easily.”

Merrill says he also turns to Halo Upmix to mix stereo 5.1 audio to 7.1 or Atmos, which continues to become an industry standard. “If I have an Atmos mix, I’m definitely using Halo Upmix,” he adds. “I think Atmos music has some really cool potential. I love remixing music in Atmos; it just has so much more space and dynamic range to use.”

Merrill began his music career recording with a band in high school, but found his sweet spot “behind the glass,” working his way through various music and video production projects. Merrill, who is also co-CEO of his own production company, Happy Yeah! Productions, has worked with many top music producers in the business. Included among them is of the Black Eyed Peas and Raphael Saadiq, with whom he worked on film scoring and music engineering. It was those projects that turned him on to audio post production.

He will also tap Halo Downmix software on the occasions when he is working on 5.1 music stems, and it needs to go to a stereo output. “In those cases, I’ll definitely reach for Downmix rather than trying to actually downmix it another way,” he says. “It’s also an easier process than asking a client to re-deliver stems, especially since they often don’t have them.”
