Presenting The Huey HD Professional Sound FX Library. During the summer of 2016 I was granted access to a 1964 Bell UH-1H Iroquois helicopter while it was being tested and certified for flight after a lengthy inspection and reconditioning. The company that owns the UH-1H allowed me to place microphones in and around it during ground tests and be present while it was test flown. The results are in this sound effects collection.
The UH-1H was moved from the hanger after scheduled maintenance and inspection to the landing pad and I was able to place several stereo microphones around and inside. A Sennheiser MKH-8040ST ORTF set was placed inside the crew compartment toward the rear facing forward. A Sennheiser MKH-8040ST XY set was placed to the rear of the main body under the tail pointed up at the turbine engine. The distance was 2 meters away from the exhaust outlet. A Sanken CSS-5 was located at the front of the aircraft just under the nose pointed up at the two-bladed main rotor. Last but not least, a Schoeps MK4/MK8 MS stereo set was used on a boom pole and a stand operated by yours truly. I was standing off to the side of the helicopter approximately 75 feet away.
The MKH-8040ST ORTF set was connected to a Sound Devices 702 recorder inside the crew compartment. Both were held in place on foam pads with micro bungie cords. The MKH-8040ST XY and the CSS-5 microphones were connected to a Sound Devices 744T/MixPre-D that was located near me so I could monitor the results and make adjustments as the tests were conducted. After the first test run the levels and positions were set and remained in place during the next six tests. The Schoeps MS set was connected to another 702 recorder that was with me.
After the final ground test the XY and CSS-5 were removed and the ORTF and Schoeps remained in place as the Huey started up and took its first post maintenance flight to the airfield across the street. I quickly packed the gear into my SUV and set up on the airfield and waited for the Huey to return. I had to work fast as I only had 15 minutes or so before it returned.
After the blade and engine adjustments were complete it was time to take flight. I placed a MKH-8040ST ORTF inside the crew compartment, a Sanken CSS-5 far way in the field, A MKH-8040ST XY in front up close and I wandered around with a Schoeps MK4/MK8 MS stereo microphone on a boom pole. Because I had no idea where the Huey was going to land after it flew around for 20 minutes or so some of the microphones set out on the tarmac and field captured some fantastic off axis sounds. I also made sure I stood at different distances every time the Huey started and departed so I could get a variety of medium close perspetives.
A full set of buttons, switches, levers, dials, pedals and pumps were recorded along with the doors from both inside and outside.
Using the library:
Below are some quick tips and information on how to use the library for maximum benefit
1. Create 4 stereo tracks in your DAW to place the stereo WAV files.
2. Most tracks are time aligned for easy editing and mixing.
3. The Schoeps MK4/MK8 MS stereo track is also delivered in mono with the MK4 microphone track only.
4. The ground test tracks can be used for “in flight” sound design.
