Help creating a realistic erj sound.

Featured Replies

If you can't record the sounds yourself with your own equipment then gather a collection of videos that have the necessary sounds. Apart from gear sounds etc and other cockpit sounds you need a set of exterior and interior engine sounds. Without fs sound studio to help you edit the sound envelopes it will be very difficult to do. Even with that it can be a pain. I have just finished (after almost 2 and a half months of fiddling) a new set of interior sounds for the VC10. The model lacked the compressor howl. The sim synthesizer loops after only 3 seconds so you will have to tweak your sounds using wavepad or audacity not just for length but for clarity. Also for clicks etc. You will need a lot of patience. Also remember that compressor whine diminishes with altitude and airspeed. Not only that I bet your corrected n2 curve is wrong too. Almost all a/c in the sim use the wrong settings leading to surge on start-up.

I do not have patience to collect videos and edit the sounds correctly. However, Anthony31 was creating a sound set for the erj, but I cannot pay any money to rent the aircraft.

Where did I say I was doing a soundset? I said I could do one. I have the equipment and the knowledge but I am not insane and I am certainly not going to spend $10,000+ on aircraft rental to make a soundset and then give it away for free.

 

The point I am trying to make is this, soundsets can either be really cheap but difficult to create or really easy to create and hideously expensive.

 

The cheap and difficult way is described by vololibersta and theredbaron. You can probably buy a flight video of an ERJ which will have video footage within the cockpit and audio and you may be able to cobble together a soundset from that. You can also scrounge through youtube trying to ###### audio from the videos there. This method does indeed require a fair amount of luck (getting some clear audio where noone is talking over the top) and plenty of time and patience.

 

The easy but expensive method is to hire the aircraft and this way you can place your own recorder where it will best record the sound as well as instruct the pilot what they should do to get the sounds you need. I have done this before (although only with GA aircraft) and it is much easier assembling the soundset than trying to find sounds in videos. For one thing you can get the pilot to do a runup at various thrust settings on the ground to get the exterior sounds. This isn't something that pilots of commerical jet flights usually do which is one of the reasons you would need to hire the aircraft. For something like a GA plane you can rent one plus a pilot for around $200 an hour. For something like an ERJ you'd be looking at something more like $10,000 an hour.

As another person mentioned, this is the purpose of payware sound companies such as Turbine Sound Studios (TSS), which possess far better accessibility to real aircraft and recording equipment at a fraction of the price. It is unlikely that you will find consistently high-quality sound from most videos, and it seems impractical to take on such a large project as a consumer flying an FSX aircraft that isn't perfectly realistic (most likely not even up to the standards of PMDG).

 

It is feasible, however, to use sounds from real-world videos for FSX videos, as many people have done.

Whether you make your own sound recordings or "borrow-ask for-acquire" sounds from videos you will have a lot of work to do.

For example the RR Conway jet engine is famous for its compressor howl. In my model that sound was completely absent inside. So, I made a recording of the engines at full throttle taken from inside. It sounded great! But, there were small fluctuations caused by vibration and hunting not apparent initially because one's brain filters them out. There was also too much roar and rumbling. So I had to filter out a large part of the sound so that all I heard was the compressor whine. That process however, enhanced the fluctuations :-(. And, in addition the sim's sound synthesizer also enhanced them further :-( :-( In effect what started out as a great sound ended up as unlistenable. However, all was not lost as I superimposed the same recording on itself thus creating a more natural hunting and vibration sound. That took weeks of tinkering and still the task was unfinished.

The next problem was to try to find a work around of the sim's inadequate sound.cfg. It is designed for props and not jets. Jet compressor noise whilst very loud on the ground diminishes with aerodynamic velocity and altitude. It's still there but you don't hear it because the sound footprint extends behind the engine due to aerodynamic velocity and altitude. Unfortunately the sound.cfg does not allow for that. All engine sounds are driven by the throttle position only. The only solution I was able to find was to lower the volume at a typical n2 cruise setting. Job still not finished!

The last problem was to find the correct pitch curve. The top end was easy enough as the recording was made at full throttle. Finding the bottom idle was very dificult and eventually solved by putting sound bytes into a keyboard and measuring the octaves and then translating that to the pitch curve. Eventually I found the sweet spot!!! But still not finished!!!!

When I accelerated and decelerated the engine the sound was windy and wooshy. So was all the hard work wasted? No, because one more job still had to be done and the problem there was the CN2 (Corrected N2) curve in the air file. Almost all the a/c available for sim use (free or payware) use the original curve produced by MS. It's totally incorrect. It's convex instead of concave. The engines suddenly jump into life at 22% n2 and frequently surge. So you don't get a smooth increase in rpm as the engine spools up to its idle setting. That has now been fixed :-) meaning a smooth acceleration to idle and to full throttle and the windy wooshy noises have gone.

If you want to do your own sounds then go ahead. But be prepared for a long road. You will need lots of patience!!!!!!!

I am not gonna create a sound set, it is time consuming and is complicated because I really have poor vision. Can someone please create for me an embraer erj soundset that is realistic and works with feelthere's embraer regional jets.

 

Thank you

Again, have you tried

of Turbine Sound Studios (TSS)? I believe a high-definition version is also in development by TSS.
  • Author

I tried both TSS sound sets, the high definition one sounds very nice but not exactly realistic.

I got some wave files for the erj's engines. How can I program the sounds using sony vegas to be realistic?

  • Commercial Member

I realize this is probably not what you're looking for but I thought I'd put it up here. I use these and thought the sounds were rather nice, although I can't vouch for realism as I have no idea what a real ERJ sounds like. They have a wind noise that ramps up at around 250 kts which always makes me smile, lol.

I believe the truth is you really can't create a sound set that would sound like a real aircraft in all situations. Some like sounds of PMDG 777 and PMDG 737 come quite close, however I think they use some custom code for certain system sounds at least...

 

Anyway I think you should start your research about how to create sounds from here:

I don't know what envelopes in FS Sound Studio to use for my wav files. Can somebody please help me.

I was able to add the sounds I recorded to sony vegas, but how do I make those into an fsx soundset?

I give up on creating an erj soundpack. Can somebody at least create for me an Embraer ERJ series soundpack temporary until adambot3000 creates one?
