A sound pack made for the ToLiSs A321/A319 and FlightFactor A320 aircraft add-ons for X-Plane 11.
It is known for its lack of immersion and accuracy compared to other sound packs available on the market.
1: "The BSS Soundpack does not have the same level of detail and quality as the FlyByWire A32NX!"
2: "I know, they don't even use the right sound for the APU! It's better than the default sounds but a bit questionable imo"
