How do you swap one airplane's sounds with another? In particular I'm thinking of QW 757 ---> CS 757. Is it even possible?

Yup, it is possible, the sounds FS aircraft use are merely wav audio files. They are controlled by a config (text) file, called 'Sound' (somewhat obviously) which tells a particular FS aeroplane which sounds to use for each action in the sim.So if you liked, you could record your car starting, make it a wav file, name it 'flaps' and put it into the default FSX 737's sound folder, and every time you lowered the flaps, you'd hear your car starting, because the config file looks for a wav file called flaps to play when you press your flaps key in FS.Depending on what kind of swap you want to do, it is either simple, or slightly laborious. When you buy something like TSS replacement sounds for an aircraft, those normally come with a replacement sound config text file as well as the new wav sound files, so in the case of TSS replacements, all you normally do is drop the wavs and the config file in your aircraft's sound folder, it overwrites the old sound config file that is in there, and Bob's yer uncle, the new config file tells your aeroplane to use the new sounds.However...If you are doing it manually - nicking one sound from one aircraft and putting it in another - what you will have to do is open up both the donor and the recipient aircraft sound config files and see what is what, as you might not want to simply swap everything.By way of explanation, here is a bit from the default FSX A321 sound config file:[sTARTERA]filename=a321_an1strtviewpoint=1link=starterA.1If I change that to this:[sTARTERA]filename=reverserA-inviewpoint=1link=starterA.1It would then use the retracting thrust reverser sound for starting the engines, which would be stupid of course, but I could do it if I wanted to. I'd probably also need to sling that audio wav file in the A321's sound folder too, but it is possible to alias it rather than duplicating it, although if HD space is not a problem, there's no real advantage to doing that and it's just easier to sling all the sounds you are using in the recipient aircraft folder as well.So, back to the 757s, you could take a chance and simply copy the entire sound folder contents of one of your 757s, and plonk them in the other one, overwriting the Sound config file, and it probably would work okay (back things up if you try that), but generally speaking, it is usually more likely that you'd want to go through the two config files and cherry pick what sounds you want. As with all config files, you can simply open them up in Notepad or any other program that can edit text files, and as with everything like this, if you are unsure, just make a copy of stuff on your desktop whilst you are messing around in order to have a way back if things go ** up.One last thing to know. Sound config files can be a bit confusing at first if you look at them, since they tend to have several start engine sounds listed when you might be expecting to see only one. Usually what that is, is the sound from different viewpoints, such as in the cockpit or on an external view (this is because FSX can use sound cones to emulate doppler effects as aircraft pass by). If you are at all puzzled by what a sound is that is listed in the config file, you can simply note the name of it and then double-click on that wav file and it should open up and play in Windows Media player (or Winamp, if you use that).Al

The easy way would be to go into the aircrafts sound folder. Make a backup copy of the sound.cfg fileAnd then edit the existing sound.cfg or create a new text file named sound.cfg with the following:[fltsim]alias=Aerosoft Beaver Standard Wheels\soundChange the Aerosoft Beaver Standard Wheels to the folder name for the aircraft whose sounds you would like to use and your done.What you have done is alias the sounds to another aircraft.If you want some more examples have a look at your aircraft folders. You may have multiple aircraft folders for one aircraft you have (like the Aerosoft Beaver which has at least 6 variations). One aircraft will have the sounds and the other aircraft will simply have a sound.cfg with the 2 lines above in it to alias them to the aircraft that does have the sounds. They do this because it saves on HD space.PS. What Al said (he posted while I wrote)

I believe there is a caveat here. If one aircraft developer has sounds of things like internal cockpit devices/afct parts and the other developer has not developed those features, you will loose the additional sounds by moving the files. For example, developer A has a sound byte for a special type of flaps and developer B does not have this same sound (or function), then if you use one sound folder in another aircraft, you won't get that sound. You're pretty safe if you only want engine sounds but you'll have to compare the two cfg files to see if the match is good.fb
