Indeed and sometimes you can actually hear the two engines phasing as they are not 100 pct in sync if you are close to them in the passenger cabin.However, from the inside it sounds quite different from the phasing sound you get in FSX (which sounds more like exterior fly by kind of thing).And in the cockpit it would probably hardly be noticable.So in my case I would rather be without it.Soren Sorry Rob, I answered Martin before I saw your post ;-)Yes I agree.Soren

Yep and the cause is the same but in Level D 767 they do not have multiple .wav files with the same sound, instead they just point to the same .wav file in the pairs of engine soundsexample from their sound.cfg:===========================================// //// ENGINE MAIN SOUNDS //// //===========================================-------------------------------------------//LOW N1 HUM-------------------------------------------[JET_WHINE.1.00]filename=767_1flags=0viewpoint=1rparams=0.07,1.0,0.7,1.6vparams=0.1,0.0,0.20,8.0,0.35,20.0,0.50,0.0link=JET_WHINE.1.01[JET_WHINE.2.00]filename=767_1flags=0viewpoint=1rparams=0.07,1.0,0.7,1.6vparams=0.1,0.0,0.20,8.0,0.35,20.0,0.50,0.0link=JET_WHINE.2.01-------------------------------------------//INTERMEDIATE N1 WHINE-------------------------------------------[JET_WHINE.1.01]filename=767_2flags=0viewpoint=1rparams=0.40,0.60,1.00,1.1vparams=0.0,0.0,0.50,0.0,0.82,14.1,0.88,0.0link=JET_WHINE.1.02[JET_WHINE.2.01]filename=767_2flags=0viewpoint=1rparams=0.40,0.60,1.00,1.1vparams=0.0,0.0,0.50,0.0,0.82,14.1,0.88,0.0link=JET_WHINE.2.02...etc.I assume one is left engine and the other right engine.So what I did was to load each of the sounds into a wave editor and reverse the wave then save the new file as <filename>r.wavThen I changed my sound.cfg to this:===========================================// //// ENGINE MAIN SOUNDS //// //===========================================-------------------------------------------//LOW N1 HUM-------------------------------------------[JET_WHINE.1.00]filename=767_1flags=0viewpoint=1rparams=0.07,1.0,0.7,1.6vparams=0.1,0.0,0.20,8.0,0.35,20.0,0.50,0.0link=JET_WHINE.1.01[JET_WHINE.2.00]filename=767_1rflags=0viewpoint=1rparams=0.07,1.0,0.7,1.6vparams=0.1,0.0,0.20,8.0,0.35,20.0,0.50,0.0link=JET_WHINE.2.01-------------------------------------------//INTERMEDIATE N1 WHINE-------------------------------------------[JET_WHINE.1.01]filename=767_2flags=0viewpoint=1rparams=0.40,0.60,1.00,1.1vparams=0.0,0.0,0.50,0.0,0.82,14.1,0.88,0.0link=JET_WHINE.1.02[JET_WHINE.2.01]filename=767_2rflags=0viewpoint=1rparams=0.40,0.60,1.00,1.1vparams=0.0,0.0,0.50,0.0,0.82,14.1,0.88,0.0link=JET_WHINE.2.02...etcNow the left engine and the right engine sounds are no longer identical, therefore no phasing/flanger.Remember to do this for all internal sound pairs and external sound pairs if you also want to get rid of the effect in external view.Soren

Hi Gary,Thanks for the details, I have never developed aircrafts in FS only scenery, had no idea so much is involved.Do you know why this was not a problem in FS9 ?Soren

You should try to listen to each of the .wav files to find out if some of them are actually the same sounds. In my case a whole range of airbus sounds where called different names but contained identical sounds.The wilco airbus has a range of sounds: ban11, ban12, ban13 etc up til ban24. Each of these are identical to the sounds in bbn11, bbn12, bbn13 up til bbn24.So what I did was to load bbn11 to bbn24 into a wave editor and reverse them then replace the original bbn11 to bbn24 with the reversed versions. That stopped the phasing completely in the airbus.Now I can taxi, turn and bank without this happening anymore.Hope this made it clearer.Maybe this is not the reason for problem with all 3rd party aircrafts (I just kind of hoped so).I have the same problem with my FSX version of the Level D 767.Will look into that one as well to see if the cause is the same as in Wilcos airbus.

Hi there,Just want to help with my recent discovery regarding the strange phasing sound effect many people (including me) gets with 3rd party aircrafts in FSX.There has been a number of posts from frustrated simmers having this problem and now I think I found the reason:In my case I had this annoying problem with my Wilco Airbus Evolution 1 series. It showed out that in the 'sound' folder a number of wave files had identical twins with different names (two different .wav files contained exactly the same sound/waveform). From my knowledge from sound engineering and sound design in music production I know that having two sounds with identical waveforms played simultaneously but just a little offset / out of sync will indeed introduce a phasing/ flanging effect. And this is exactly what happens in FSX with these identical sounds.So what I did was, I loaded all the twin sounds into my wave editor and simply reversed them (made them backwards) so they no longer were identical with the other ones (can't hear the difference with a looped engine sounds anyway). Then I replaced the original sound files with the reversed ones. Now the phasing effect has completely disappeared.Hope this is useful for all the simmers having this problem./Soren
