Just to fill out my first message. All I can say is that PMDG has made a quite comfortable soundset :) Nothing negative in that :D to the best addon so far for FS9. But the feel of being there is missed.Hope they will make the 744 soundsets more realistic. :-wave CheersJohan "Whats VNAV?!?!" Adolfsson:-wave

Thanks for that! err...interesting camera there...and I don't think my copilot sings for me :) But the T/O was interesting. It just encouraged me to try to tweak my sound some more :)

Well, after fishing the library, I found this http://library.avsim.net/download.php?DLID=48419 to be the closest match to what I hear on the videos!

Hello guys, Its me cfm56, the oriniator of this whole mess lol. First I want to thank all of u guys(every single one of u) who posted something here in efforts to either support, set me straight,or just puttin in your two cents.I just spent the last two hours speaking with dude from my school (for those of u who asked that the vaughn college of aeronautics and technology, laguardia airport where im studying to become a pilot) who knows this stuff enough to build his own cfm56-7 if he had the time and money. He was able to confirm MOST of the things u guys told me in these posts.Beginning from the top of the posts all of these were written down as he spoke: 1) He was able to confirm that different microphone pick up sounds differently. 2) The sounds within an engine series(cfm56-7 - cfm56-5c for example) will differ SLIGHTLY as the bypass ratio differs( for reasons which ill attempt to explain later). 3) Weather DOES play a role in the way the engines sound. Density, for one, is a major factor. High density = more molecules of air per given volume of air, in turn, sounds travels faster and somewhat takes on a richer tone. Air temp is a next one that makes a difference. Cold air = more DENSELY packed air producing same effects described above.I would like to take this time to thank RELLEHENK for that awesome video, those whining sounds that u guys hear(from the cocpit) followed by the roar/inaudible growl at takeoff is EXACTLY what im talkin about. ThanksThe things my friend didnt subcribe to is the statement "NOT ALL ENGINES OF THE SAME TYPE SOUND THE SAME." Im goin to leave this one alone, have the response but time is limited(2:18 and havnt slept a wink since i woke up at 7 sat' morning)However Daniel. P i need to respond to this one:"Neither, because Aaron Swindle did the sounds from this aircraft. In any case, I doubt it's identical... Now, to the guy who's using an A343 engine and a 735 soundclip to prove this:That's laughable. The 777's engine is a RR, as is the 757's. Should I compare them? Are they the same engine? Please. Hell, do the old RB's for the 757 sound the same as the new ones?"Ill start here, u said u DOUBT it is, im telling u that it is. the gear sartup, shutdown, eng idle (internal) eng spoolup (internal) and others are the exact same thing, i listen to each files side by side and individually. The fact that u said u "doubt" give me the impression that u dont have aaron swindles 777 digital sounds, question remains how do u know that he recorded from the 737. Secondly if he recorded from the 737 to sell to the public y not call it the 737 digital soundset.? Now, one CAN compare the 777rr to the 757rr engine, y, bcause they are both turbofan engines. Ill attempt to explain for the record what is a turbofan engine in my next post. The same goes for the a320, b767, b747, a340, a380 - soon comin out gp7000, b777, b737, and the list goes on and on. They are all high efficiency, medium to high bypass engines, and they all- each respectively- exhibit that turbofan characteristic- high pitched whine, some type or roaring sound, and a growling noise not to mention some type of humming noise. Each of these come at a different throttle setting,diferent sound level, some are heard more than others but they are all there. Are there any other sounds in that batch - yes but time is limited and the factors that govern them are too many.However, right now im just at a point (thanks to u guys) where im like, so what- even though im weary of that 737-777 issue- they did a damn good job on the panel and aircraft model.I was going to post a list of reasons y these engines make the general sounds they do but I miss my pmdg(havent flown it all weekend. maybe tomorrow or sometime. Gideon

In several posts you say that both sounds are the same and that is a strong statement. So it will be nice to see some analytical background, like a spectrogram or at least some short time FFT, that could fundament the affirmation. Jos

Hey J Oliviera, Are u talkin bout the 777 digital soundset? If u are im not sure what a "short time FFT" is. Neither do I know how to come up with a pic of a spectogram I have recording software on my pc but dont know how get a pic of it. Oh BTW guys I am attempting to come up with my own soundset, but I already promised the person not to distribute the files on the internet. And on top of that this sound editing is quite a daunting task d/to fact that I dont know how to write the code for the sound.cfg. Right now im playin with the numbers by trial and error to see wat happens when I do this. But its not easy.

So, How did you came to the conclusion? By file compare?Jos

By simply listening to the both of the soundsets. The first time I listened to the 737 sounds the first question that came to my mind was- doesnt that sound like the 777 soundset?. Y, simply bcause I recognised the sounds. Then i started to do an in depth comparison. The only thing different between pmdgs 737 soundset and A Swindles 777 soundset is the external whine sounds(everything after the ext eng startup and bfore the ext eng shutdown), which are a bit believable to me based on wat ive heard at the airport(. Every thing else is the exact same bet the two- gearsounds, startup, shutdown, flaps, eng idle, spool, full power thrust snz and im sure there are almost two others that I cant bring to mind right now. I would send u copy of the startup so u can hear for yourself but I would need mr Swindles permission, I believe. However if u heard it u would say the same thing, trust me.

As a someone who has dealt with audio issues for most of my life, what you are describing is simply your impression of one sound against another. Many people would probably disagree with the results of your comparison, so as it stands now, it boils down to your "opinion" vs other "opinions" as to which sound is right and which is wrong. Like in both politics and religion, who is right and who is wrong may take generations to figure out. In the mean time, making statements like " this sound doesn't sound like that sound " without any scientific backup isn't worth a whole lot.

In that case in my opinion should be "sounds like" and not same sound. To say that they are the same you must show some analytical evidence. Jos

Hi Bob,Your description has persuaded me I should probably try FSHotFSX. Some questions, first, if you don't mind?1. I assume FSHotFSX sounds enhance, and not replace the PMDG sounds? That's the way I would want it to be, by the way!2. Did you try out FSHotSeat? Any particular reason you didn't go for it?3. Can you fly using the demo, or do you just sit and listen to the sounds(ie non-interactive).Thanks for the recommendation,BR,Frank

It doesn't replace the PMDG sounds, just enhances them and you have a menu option to use the default sounds anyway, in case you don't like what you are hearing. I left everything on and am happy with it. Wait until you here the AI Commercial aircraft landing sounds complete with thrust reverser sounds and tire screeh. I didn't get the version with the Co-Pilot , because I had a program a couple of years ago with a Co-Pilot and didn't care for it. Might be worth a try, if you like that sort of thing.

Hey guys, point well taken. However Im not sure what type of "analytical evidence" u guys r takin about so if u can tell me Ill try to analyze the two soundsets thru those mediums. In the mean time (since u guys have the sounds mentioned above) Ill be willing to send u two a copy of the startup, shut, idle, flaps and gear sounds if it makes a difference. The only thing I will require of u two is that u trust me that im not making this up. Trust me that im not taking pmdg's soundfiles and renamaing them bcause as soon as u hear these sounds itt will be VERY easy to make that assumption. I just finished listening to the sounds again and there a MINOR differences in the gearsounds so im sure ull know that the sounds come from a different package. If u guys are willing to TRUST ME altogether ill be willing to send the files to your respective email addresses. If not tell me what i need to do to make a verifiable analyzation. Gideon

If you want to compare two sound tracks - the only analytical way to prove they are identical (regardless of volume) is to run Fourier analysis on them. You will essentially decompose both into their frequency spectrums.Michael J.WinXP-Home SP2,AMD64 3500+,Abit AV8,Radeon X800Pro,36GB Raptor,1GB PC3200,Audigy 2

If I am not mistaken, you made the following statement in your 2nd or third post and I quote:"Listen up guys I have been on the 738 many times and I know for a fact that the pmdg sounds are not what they should be, and I can prove it."Now, in all your posts that I have read so far on this topic, you have failed to do this for me or anyone else. I have a very technicalbackground, and if someone makes a statement that they are going to "Prove something", especially if they are knocking an existing product, I want to see some concrete proof. Until then, you have proved nothing in my opinion and until you do come up with some proof, it seems to be just more of you trying to talk around the fact that you have no proof, never did, and your statement quoted above was just your personal opinion.
