Engine Sound FG

From Elite Wiki

This OXP creates an engine sound that follows the speed of the your ship, thruster sounds when maneuvering, and some additional sounds.


Oolite version 1.79 or later.


Download .oxz file and move into the AddOns folder of your Oolite installation.

If you want to change the volume or other settings, rename the download file to .zip and move its contents (3 folders and 2 plist files) to a sub folder (e.g. "Engine Sound FG.oxp") in your AddOns folder. The settings can be found in the file engine_sound_fg.js in the "Scripts" subfolder. You can modify the volume levels of engines, standby sound and maneuvering sound separately, you can disable torus, maneuvering and/or cooling fan sound if you want, and you can control the behaviour if you have BGS OXP installed as well (see below).

This OXP is based on ideas developed in the Oolite forum and on a demonstration OXP by Norby. An updated version of Norby's OXP is available under Engine Sound.

Most sound files were taken from BGS OXP by Pagroove, PhantorGorth, Thargoid, Tricky & Svengali, and modified by Norby. The fan sound files were made from a file from freesound.org where it was uploaded by suzzy457 and licensed under CC BY 3.0 ([1]).

Differences to Engine Sound OXP by Norby (apart from the additional sounds)

This OXP uses the same 25 sound files as Engine Sound but choses them in relation speed/maxSpeed. Norby's OXP uses the absolute value for speed for file selection, so slower ships will sound differently at top speed than faster ships. With this OXP, all ships sound the same but can use the full "spectrum" of the available sound files.

Obviously you shouldn't install both OXPs at the same time.


BGS OXP compatibility

BGS uses a constant ambient engine sound when speed > 0 (using the sound file that is played at 25 different speeds in this and Norby's OXP). So in BGS you can't hear speed differences, and this actually started the forum discussion mentioned above. BGS uses two additional sound files to create accelerating and deceleration noises - the files are used in this OXP for the torus drive.

BGS and this OXP can be used together, but if the BGS ambient sounds are left on, not only the crowd noise and the radio chatter will be played but also a (constant) engine sound. The "double engine" doesn't sound bad but is of course a little bit louder, so it could be a good idea to increase the maneuvering and perhaps the standby sound volume (BGS turns off its engine sound completely on standstill).

There is a switch in engine_sound_fg.js to turn of the BGS ambient sounds. If both chatter and crowd noise have been disabled in BGS, the BGS engine sound will be turned off in any case.
