76 6. MODIFYING AN AIRCRAFT’S PROPERTIES<br />
First, <strong>the</strong>n, one must understand <strong>the</strong> structure of <strong>the</strong> default sounds directory. The default<br />
sounds are located in <strong>the</strong> folder:<br />
X-<strong>Plane</strong> 10/Resources/sounds<br />
In this folder are <strong>the</strong> following subfolders:<br />
• “alert,” which contains sounds for altitude warnings, system failures, and navigation alerts,<br />
among o<strong>the</strong>r things.<br />
• “contact,” which contains sounds for crashing into <strong>the</strong> ground, and touching down on <strong>the</strong><br />
water, as well as for <strong>the</strong> rolling and skidding wheels on pavement.<br />
• “engine,” which contains sounds for <strong>the</strong> many different kinds of engines modeled in X-<strong>Plane</strong>.<br />
• “radio chatter,” which contains communications between aircraft and ATC. Note that this<br />
is <strong>the</strong> only set of sounds which apply globally and may not be customized by a particular<br />
aircraft.<br />
• “systems,” which contains sounds for <strong>the</strong> humming of <strong>the</strong> APU and avionics, <strong>the</strong> moving of<br />
flaps and gears, and <strong>the</strong> firing of guns and flares.<br />
• “wea<strong>the</strong>r,” which contains sounds for thunder, wind, and rain.<br />
Each subfolder contains a number of WAV (uncompressed audio) files corresponding to <strong>the</strong><br />
different sounds that would be heard in X-<strong>Plane</strong>.<br />
To use custom sounds, <strong>the</strong>n-that is, sounds which override <strong>the</strong> default ones-you would create a<br />
subfolder in your aircraft’s sounds folder to match <strong>the</strong> structure of <strong>the</strong> default sounds folder, <strong>the</strong>n<br />
name your WAV files with your aircraft’s name as a prefix, like this:<br />
[.acf file name] [name of .wav file to replace].wav<br />
For instance, if your aircraft file was called ”MyCessna.acf” and you wanted to use a custom<br />
altitude alert sound for your aircraft, it would need to be located here:<br />
[Your aircraft folder]/sounds/alert/MyCessna altitude alert.wav<br />
Note that <strong>the</strong> sample rate of <strong>the</strong> WAV files you wish to use should be 22.050 kHz. You can likely<br />
set your recording device to this sample rate before you begin capturing your sounds. Alternatively,<br />
an audio editor (such as <strong>the</strong> excellent, free, cross-platform Audacity) can be used to change <strong>the</strong><br />
sample rate.<br />
When using custom wind sounds (saved as [your aircraft directory]/sounds/wea<strong>the</strong>r/[.acf<br />
file name] wind.wav), X-<strong>Plane</strong> will scale <strong>the</strong> volume of <strong>the</strong> recorded sound depending on <strong>the</strong><br />
speed at which your aircraft is flying. In order to do so, you must set <strong>the</strong> knots indicated airspeed<br />
at which <strong>the</strong> wind sound was recorded. This is located in <strong>the</strong> Engine Specs dialog’s SFC/Sound<br />
tab; in <strong>the</strong> bottom third of this window on <strong>the</strong> far left is <strong>the</strong> setting labeled “speed that wind<br />
sound was recorded at.”<br />
Likewise, engine sounds (stored in [your aircraft directory]/sounds/engine/) are scaled<br />
in both volume and pitch based on <strong>the</strong> engine speed at which <strong>the</strong>y were recorded. The bottom of<br />
<strong>the</strong> Engine Specs dialog’s SFC/Sound tab houses <strong>the</strong> settings for <strong>the</strong> RPM or N1 speed at which<br />
engine and propeller sounds were recorded.<br />
6.3 Setting <strong>the</strong> View Properties<br />
When flying in X-<strong>Plane</strong>, <strong>the</strong> pilot’s inside-<strong>the</strong>-cockpit view is fixed at some point on <strong>the</strong> aircraft.<br />
To set this point for your aircraft, open <strong>the</strong> Viewpoint dialog box from <strong>the</strong> Standard menu. It<br />
will open to <strong>the</strong> Default tab. There, in <strong>the</strong> left-center of <strong>the</strong> window, are <strong>the</strong> “long,” “lat,” and<br />
“vert” arms of <strong>the</strong> pilot’s viewpoint. These are standard position controls, as discussed in <strong>the</strong>
