FSLABS A321 MSFS CFM SOUND PACK

  Immerse yourself in the most realistic Airbus A321 sound experience ever created. After 10 years of development, supported by pilots and ground personnel, this sound pack delivers unmatched authenticity with every sound recorded from real Airbus aircraft and scientifically matched to reality. Experience the iconic CFM56 engines, from windmilling at low speeds to the raw power at higher thrust settings, with every detail crafted to perfection. Dynamic sound profiles adapt to each phase of flight—ground idle, takeoff, climb, cruise, descent, and landing—seamlessly changing tone and pitch with speed, altitude, and atmospheric conditions. Vibrations and bass feedback evolve as the gear leaves the ground, transitioning from ground vibrations to fuselage resonance, creating an immersive journey from startup to shutdown. Using real-world audio samples and precise engineering, every layer of sound, including N2, exhaust, and atmospheric effects, perfectly aligns with actual aircraft performance. Whether in the cockpit or outside, this sound pack brings the true essence of the Airbus A321 to life like never before. Watch our video comparison to hear the difference and experience the ultimate immersion.  
Other completely reworked and changed features of this pack are: ventilation system with blower extractor, electrical system with contactors and hum, fully redone packs, that could be heard when the door is open, PTU, cabin ambiance, passenger ambiance, cabin fans ambiance, engine startup and shutdown from cabin, cockpit and outside, the touchdown sounds dependant on the force of impact, the runway bumps and roll, wind sound, turbulence sounds, gear wind, flaps wind, reverse sound, reverse hydraulic and much more. All other original features that were exact are kept also. Explore yourself and you will find every sound present in this pack as in real aircraft.

### CFM 56

- Total of 327 sound samples that build the IAE from scratch – all outside and inside in 360 degrees with proper cones  
- Each element of engine sounds depending on state and outside conditions  
- Core  
- Exhaust  
- Fan  
- Startup and shutdown  
- Vibration that reacts to physics – some vibration on the ground, more vibration once the gear leaves the ground  
- Jet blast that penetrates the gear doors – if they close, it moves out  
- Ground effect of the engine  
- Speed, altitude, and Mach speed effects on engine sounds – they sound different at any speed and condition  
- Pitch and volume of each 10% of N1 are scientifically and musically designed with correct formulas to present the most realistic engine sound ever created for this type  
- 10 years of work on each CFM and IAE type – improved every year  
- Every seat on the plane makes the engine sound different  
- You can hear outside engines if doors or windows are open  
- Shaking panels from engine vibrations  
- Rush, air effects  
- Hiss effects  

And much more! Better to experience one type for yourself than just read about it! ;)
