This can often be a very unpopular thing to say, but I think these sound enhancements are payware quality, and I would pay a (reasonably modest!) amount for good sound enhancements like these, for other aircraft and aspects of FSX.
The likes of TSS do it almost exclusively with aircraft sounds, so perhaps "Inwood Audio" could concentrate on internal / ambient audio enhancements.
Eg.... The feelThere Airbus Series (still the only half-flyable airbus at the moment!), I fly quite a lot but it has awful interior sounds (switches, knobs, clicks, flaps, detent, cooling etc) .... but they're all in the Feelthere folder and quite replaceable (I have transferred most interior sounds from another aircraft for now).... and I would certainly pay for a 'Sound Enhancement' package for aircraft like this. :smile:
@Summer1 .....Would you read your posts ........... Get over yourself, and show some respect!...... Steve's given you an explanation for his decision. You're like a spoilt kid spoiling the fun because you can't get your own way. :rolleyes:
