[Sound Feedback for the Ini team]

12 hours ago, FailCold said:

Hey Ini team, congratulations on the release.

I have some feedback regarding the sounds:
 

• The engines sound good overall, but could do with more bass at high N1 settings. These are big, powerful engines and should sound as such!
• The engines fade at altitude, which is semi-correct - actually, the fading phenomenon is a function of the plane's TAS. As TAS increases, this should result in a slight fade but mainly a Lowpass filter being applied, so that all you hear at cruise is a gentle rumble/low frequency vibrations. This can be evidenced by the typical "bass drop" that you can hear on most planes IRL when starting descent - as the engines roll back.
• The packs should be louder both in cockpit and throughout all parts of the cabin. There should be a noticeable increase when packs are on, and a noticeable decrease when they switch off.
• There are no fuel pump or hydraulic sounds that I can hear - these should be audible in the mid section of the cabin, and from the outside. It would be great if the HYD pump sounds, if added, could pitch modulate according to demand, like IRL (as HYD pressure decreases with demand from FCTL surfaces, the pitch of the sound wobbles slightly). This would really bring the plane to life.
  
  As an experienced sound engineer and frequent flyer on CF6 powered birds, I'd be very happy to do some testing and provide more targeted audio feedback if that would be helpful to the team 🙂

Regarding point #2, TAS isn't the only cause of this phenomenon. Pressurization (ie. cabin delta pressure) also plays a role. Part of the low bass rumbles are the sound waves travelling through the airframe. The High pitched whine, the one that get damped low-pass filter style, are travelling though the air from the outside. Since the outside air gets thinner... Those sound waves have a much harder time reaching the inside of the cabin.

[Suggestion: Make engine quieter (apply low pass filter) as aircraft gains altitude to simulate pressurization]

Hello guys,

 

Thanks for the great product.

One suggestion (something that might have been there already in the XP version ? I forgot).

IRL, as your aircraft gets higher and the differential pressure increases with pressurization, the engine sounds gets filtered. Basically as if a low pass filter was applied progressively as you climbed.

Technically, it means that the high pitched part of engine sounds from outside are "muted" by the differential pressure, but the lower, bassy sounds can still be heard in the cabin.

Also, at some point during climb, the dynamic wind sounds becomes the loudest and engines aounds gets very faint in comparaison.

See here: 

 

You can compare the sounds between the 4th, 5th and 6th minute mark 😄 

Currently we can still hear the engine whistle at idle while descending at FL300, that should not happen.

I think WWise allows to put such filters quite easily.

 

Thanks !

[Ready to buy a cargo version]

I'd sell 3 kidneys for expansions starting with PW engines and then cargo, ACJ, MRTT, A300...
