This guide is for PC Only as Xbox does not have a way to access files. Additionally, this only works on base aircraft or non-payware planes.

Introduction

Haven’t you always wanted to have a custom sound as your stall horn, such as a dog barking? This guide will show you how.

Your Custom Sound

First, take your custom sound and make sure it is in a .WAV file format. If it isn’t, you can use an online converter to change it to that. Otherwise, it will not work.

Now, take your sound file and drop it into the sound folder of your aircraft. Typically, it will be:
<AIRCRAFT NAME\SimObjects\Airplanes<AIRCRAFT FILE NAME>\sound

Drop it in there.

The folder should now contain the Wwise package, the .XML file, and your custom sound.

Editing the .XML file

Open the .XML file using the text/code editor of your choice. It’ll look something like below.

Use “Ctrl + F” to find the name of the sound you want to replace (i.e. if you were replacing a stall horn, search for “stall”)

You will be taken to this:

In this case, we will only need to edit the “STALL_WARNING” line. Change the word under WwiseData from “true” to “false” (It is important to keep the quotation marks) Now, type the following on that line:

`FileName=“<The .wav file name>”

That line should now look something like this:

:warning: This must be done to every line that has your keyword, for example if there are two Stall warning lines, you will need to override both. :warning:

Use “Ctrl+S” to save and now close the text editor.

Regenerating the Layout file

Now that we edited some of the aircraft code, we need to re-generate the Layout file. This can be a lot of work, so you can use an automatic generator such as MSFS Layout Generator.

(In case you were wondering-the Layout file is found in the first folder of the aircraft, right before opening the SimObjects folder)

Your sound in the sim

You should now see your custom sound in MSFS at this point! Enjoy your new sound, and have fun flying.

If you have questions or if something did not work, please reply to this topic and I will help answer to the best of my ability.

Hi,

I have purchased some custom sounds for one of my aircraft for MSFS, and I followed all of these instructions carefully and correctly, but it seems that whenever I try to test to see if it’s working, there is no sound for the aircraft at all. The switches are not producing any sound, there is no sound from the APU, nothing.

It may be to do with the MSFS Layout Generator, because I am almost certain that the coding is correct.

Would it be possible for you to help?

Thank you.

Would it work with an aircraft with .PCK sounds?

Yes, I actually got it working now. The issue was that the directory was too long to regenerate the layout.json file, so I used the FTSIM+ sounds, which make their own directory of the aircraft, and I added my custom sounds into their XML file.

Another query I had though, is if anyone knew how to trigger sounds at a certain altitude, for example, the hydraulic pump sound on the Boeing 777 at 30 feet, just before touchdown. Does anyone know how to trigger custom sounds at this altitude? I attempted to do this, but I had no luck.
