With the latest updates, the cloak "rumble" sound has changed. It used to be some spooky wind noise, now it is a very penetrant beeping sound. Many people are actually using their own sounds as replacement, simply because editing sounds files is not considered cheating, so everyone is free to do so. Here you'll see how easy it is to replace the sound, together with a few sample sounds.

Note: Patches might overwrite your edited sounds, so you should always have a folder with back-ups of your custom sounds. Also, these sound alterations will only be audible in your local version of Discovery. Other people will hear whatever sound they have in their installation assigned.


Step 1: Get your favourite cloak sound file. Make sure it is a .wav file. You can convert sound files online if necessary, just google "sound converter tool online".

Step 2: Find your Discovery Freelancer folders. Go to \DATA\AUDIO\SOUNDS\ENGINES.

Step 3: Locate "jumpdrive_survey.wav" - this is the file you want to replace. Make a back-up of it if you want, and simply paste your file here, delete the old jumpdrive_survey.wav and rename your file to jumpdrive_survey.wav. Done. You don't even need to restart Freelancer to have the change happen in the game.


The sound starts to play continuously the moment any cloaked vessel is in range of 3.000M of your ship. Note that this starts to play once the model/hitbox enters the radius, not the center of the model. If you are, for example, flying a battleship and are cloaked, people will not only hear your cloak from 3K but already at 3.5K, depending on the size of your ship. A cloaked Nephilim might even trigger the sound already at 4K, depending on how it is aligned to you.
