Is it possible to make engine sounds quieter when the canopy is closed?
Is it possible to have the engine sound different when you are in front of the
intake and can hear the compressor, than when you are nearer the exhaust and
hear the roar of the nozzle more?
Yes, I did that for the F-16 already:
<engine>
<name>engine</name>
<path>Sounds/jet.wav</path>
<mode>looped</mode>
<property>/engines/engine/running</property>
<orientation>
<x>0.0</x>
<y>0.0</y>
<z>180.0</z>
<inner-cone>180.0</inner-cone>
<outer-cone>360.0</outer-cone>
<outer-gain>0.2</outer-gain>
</orientation>
<volume>
<property>/engines/engine/thrust_lb</property>
<type>lin</type>
<factor>0.000034451</factor>
</volume>
</engine>
Note the inner-cone, outer-cone and outer-gain section.
The inner code defines which section doesn't get affected (so between 0
degrees and 180 degrees the amplitude won't change).
The outer code defines a the section where the amplitude gets faded to
"outer-gain".
Note that this is in the 3d cockpit orientation.
See FlightGear/docs-mini/README.xmlsound for more information.
