Immersive Audio's first venture into MSFS soundscapes covers one of the most popular helicopters for the sim - CowanSim R66. It's certainly one of the most detailed sound packages developed for the civilian helicopter, you will hear all the details you can hear in the real R66, and beyond. Immersive Audio recorded the real R66 from multiple angles, in a total of two recording sessions, simmers can be sure that the quality of the sounds is second to none. All the sounds are derived from 96khz, 24-bit recordings, and absolutely no sacrifices are made to the quality whatsoever. The sounds will really transform how you experience this helicopter, it will suddenly feel like a breathing machine. Features:

• All sounds are derived from 96khz, 24-bit recordings
• Over 240MB of high-quality sounds and long loops for big audio variations
• Completely authentic startup, shutdown, idle, and full-throttle N1 sounds
• Completely authentic sounds of cyclic, collective, and pedal movements
• All buttons, switches, knobs, levers, and door sounds, are derived from the cleanest in-cockpit recordings
• Battery/gyro and air conditioner, including authentic spool up and down, with circuit breaker sound
• Battery sound depends on voltage
• Authentic cockpit vibration sounds during slow-speed hovering
• Dynamic blade slap sounds depending on various factors, tweaked after real R66 pilot inputs
• Rotor blades noise that changes based on collective/blade angle
• Completely authentic open door(s) sound environment. It's not a classic switch from internal to external sound mix
• Sounds of dust particles hitting the airframe on takeoff and landings, for better perception of AGL and enhanced flying audio immersion
• Rotor sounds are reflected off the ground at really low altitudes
• Don't leave the door open during takeoff and especially flight, it will get very loud! Wind noises depend on blade angle and aircraft speed
• The rotor blade sound matches the blade's RPM during startup and shutdown
• Authentic transmission whine, especially audible after shutdown
• Low RPM and ELT warning alarms
• Scrape sounds if you love to destroy the paint on the landing skids. It will tell you how good or bad your takeoffs and landings are
• Seatbelt On/Off sounds, activating in the appropriate moments
• Airframe vibration low-frequency noise, depending on the rotor stress level/blade angle
• Engine cooldown sounds. Don't touch any hot parts
• Touchdown thumps, depending on vertical speed
• Fully authentic exterior sounds that change dynamically depending on distance, speed, altitude, and viewing angles
• If you get close to external views of the helicopter during flight, you will hear an authentic wind sound hitting the camera microphones/observer
• Police radio chatter can be activated via a reserved cockpit switch
• Dynamic windshield rain sounds, depending on the amount of rain and wind hitting the windshield.
