The duo, who left Noise London when it went into liquidation last month, have formed United Audio Project and will work closely with Halo but operate from Noise London's facility, The Hat Factory on Hollen Street.
Mainzer believes that bringing the companies' respective audio and video talents together makes a lot of sense financially. “It is very difficult for a company that works on TV factual to make money without a link to a visual post house,” he said.
The move is just one element of Halo's continued expansion, which has seen it take on a new building on Chancery Lane that will offer eight offline suites.
Halo managing director John Rogerson said he was able to expand because his costs are kept to a minimum.
“We are doing well because our overheads are really low,” he said. “We are paying a good price for our main building on Great Portland Street. We took a short lease because the site was up for development [but] we didn't think it would get approval and sure enough, it didn't. Our new lease is very cheap, too.”
He added: “Our kit acquisitions have been low cost. An endorsement from Digidesign makes our audio kit very reasonable and our VTs and Avids have been purchased from companies that have gone into administration.”
Halo Post Production has grown over the past eight months from four offline, one online and one audio suite to 20 offline, three online and three audio.
