Product Description
On March 17, 2017 two UH-1N Iroquois helicopters flew over my house and were flying around the area so I hustled to the local airport and there they were, parked on the tarmac. I spoke with one of the crew members from the 36th Rescue Squadron (36th RQS) at Fairchild AFB Washington. He was left behind while the others were out flying around and he informed me they were conducting “over water” search and rescue training on the lake. They would be flying in and out all day. As soon as I heard him get the call they were on their way back I prepped the SoundField ST450 MKII Ambisonic Microphone for recording. The SoundField ST450 MKII has internal heaters and they can take a few minutes to warm the capsules so the humidity doesn’t effect them. Once I had the microphone on a boom pole I was ready to step outside onto the cold, windy runway.
Only one Huey flew in to swap crew members and then it was off to the lake. A short time later they both flew in and landed for a lunch break. I patiently waited for the Huey crews to return so I could record them starting up.
It takes them quite a while to prepare and safety check the helicopters for departure so I had plenty of time to set up the SoundField ST450 and have my Schoeps MK4/MK8 MS rig on the boom pole. I placed the SoundField ST450 approximately 150 feet in front of the helicopters. My goal was to get a nice balanced Ambisonic recording so I used a microphone stand and the SoundField ST450 was centered between Hueys. I had the Schoeps MK4/MK8 MS microphone in my left hand using a boom pole and in my right hand was my iPhone to record the video. It was so cold my iPhone ran out of power and shut down right after the helicopters started their departure from the middle of the runway.
A couple weeks later one of the helicopters returned for some additional training flights. I recorded this one starting and departing.

Included are 4 channel SoundField B-Format, M/S encoded raw and decoded stereo WAV files. The M/S encoded files are interleaved stereo with the mid on the left and the side on the right. This makes it easy to use the leg picker in Soundminer to choose which channel you want to utilize. You may also change the ChannelLayout field in Soundminer to M/S on these files to audition MS decoded stereo.
ST450 MKII generates audio in any format including mono, stereo, M/S, 5.1 surround and beyond. SurroundZone2 unlocks the information captured from any of the SoundField microphone systems and gives unprecedented control over a wide range of microphone parameters from a single intuitive user interface. SurroundZone2 will be available FREE of charge to give anyone the freedom to manipulate SoundField B-Format and A-Format files.
