Hi,
I would like to add a rumbling wav sound to be played during taxi, during take off when accelerating on the runway and also during landing after touch down.
Can you please tell me which wav file FS uses for that purpose and where it is located ?
I am using FS9 with PM, PMsounds for the cockpit sounds and POLKY 737-800 with its original sounds package.
Thanks in advance,
Nick
Hi Nick,
I am shooting from memory here so forgive me if I am mistaken... but take a look at the SOUND.CFG file for the aircraft you want to add the sound to. Using the find feature of wordpad or notepad, look up BNROLL.WAV and once you have found it, that is the sound file responsible for the rumbling noise. Within the CFG file, you can edit how loud that particular sound is. If you want to change that sound, just take the .WAV file you want to use and rename is BNROLL.WAV and replace it in the sound folder. Backup everything first before you do any editing tho!
Hope that helps,
Matt
Nick,
Just kidding ;) I found where the sound is actually located. The wave file is located in the main FS sound folder. There should be 2 of them, called BNROLL.WAV and BNROLL2.WAV. You can replace these with new files to get different sounds. I know these are the sounds responsible for the rumble, but I am still trying to remember/find where you edit them into the sound files. If anyone else can help that would be great, but I will also keep looking!

Hi Matt,
Thanks for the info :)
I will try this asap, and let you know.
;)
PS. Hav a great happy new year :)
Hi Nick,
The name of the sound file used for ground roll depends on the aircraft being used and the sounds that have been incorporated. In the case of FS default aircraft and many freeware addons such as Posky they use bnroll.wav & bnroll2.wav as Matt suggested however if a customized soundfile has been created they may be called something else. It's easy to find out though.
Open up the sound.cfg file located in the specific aircrafts sound folder using windows notepad (or any text editor), scroll down to the bottom section and look for an entry titled below:
[GROUND_ROLL]
filename=732RODAJE
flags=0
minimum_volume=8000
maximum_volume=10000
minimum_speed=3
maximum_speed=160
minimum_rate=0.85
maximum_rate=1.1
link=GROUND_ROLL1
[GROUND_ROLL1]
filename=732RODAJE2
flags=0
This is an example of my Posky 777 for FSX. There are two files linked together by the "link" command so that both soundfiles play together when the wheels are on the ground. The first file is the low frequency rumble of tires on the tarmac and the second file is rattles and sqeakes heard in the cabin. As you can see the first soundfile has a number of parameters associated with it giving extra dynamics so that the sound increases as speed increases (note that the max volume of any soundfile is 10000 so there's nothing to gain from increasing this value beyond despite what you may see from many developers).
You have many options to change or replace these sounds as you desire. I tend to experiment with wave files from other aircraft or tweak the current wave files using a suitable sound editing program increasing the bass frequencies for more rumble etc. Remember if you use a wave file from another aircraft you will need to copy it into the sound directory of your Posky and edit the above entry in your sound.cfg file replacing the old name with your new chosen wave file. Just enter the name of the new file leaving out the extension .wav Save and fly.
Hope that helps,
Ken.
Ken,
Thank you for posting that. I don't know why I was unable to remember that it was located in the aircraft sound config! Now I also intend to replace some of my sounds and make some mods for the speeds etc.
Happy New Year everyone!
Matt
Thanks Ken and Matt again,
I replaced the file already and I am experimenting right now
I really appreciate your help guys :)
Have a great year,
Regards,
Nick
Great information ! :D
Now I will go ahead and alter my sound files so the 737 sounds as it should and my Buttkicker do what it is supposed to.
Best and Happy New Year to all,
Bjorn
If I may, an old trick I saw in my pro aerospace days was the editing of sounds like this. In a desktop sim setup you likely are fine with the default "rumble". For you folks with all this immersion you likely have subwoofers employed. Problem is you have to boost the bottom registers to get that heavy runway sound and that impacts all the sounds in some way. It is possible to edit the rumble.wav sound and "dial up" the lower frequencies of that rumble so that they hit the subwoofer well.
I used to see a lot of trial wav editors around. Worth a try!?

And an excellent suggestion Peter, with more and more using Buttkickers its paramount that the correct sounds have bass frequencies within the range required but you don't want all that bass in other sounds. For a good free audio editor I suggest something like Audacity as its pretty easy to tweak the sounds, however there are many others out there also.
Good to see you here and part of Cockpitbuilders.
Ken.
