Holophone’s H2-PRO microphone helped record surround-sound audio elements for the soundtrack of “Truth in 24,” an NFL Films production chronicling the Audi team’s quest for victory at France’s annual 24-hour car race, 24 Hours of Le Mans. Sound mixer Kyle Hartigan used the H2-PRO trackside.
The full-length feature was shot in HD and features a surround-sound mix of the event. Hartigan not only used Holophone’s H2-PRO to capture sounds on the track but also from the audience and in the pit. He also brought the Holophone into town to capture the sounds of the region, including a local church, a street parade and a crowded market. All of the sound effects are based on the Holophone; the entire bed of the movie is 7.1 surround sound.
As the lead sound mixer throughout the entire project, Hartigan spent three weeks in Le Mans capturing both the lead up to the race and the entire race itself. Hartigan and his four-person sound team used the Holophone H2-PRO along with Sound Devices’ 788T digital recorder. Hartigan was driven in a golf cart around the track to record different unique locations.
The H2-PRO contains eight mic elements, now featuring Sennheiser MKE 2 mic capsules, arranged to coincide with the typical surround speaker setup found in a studio or home theater. The structure of the device and the configuration of the mic elements allow H2-PRO users to capture, from a single point, an immersive 3-D audio experience.
