We've had a few enquiries about how the volume of individual sounds can be adjusted in the cockpit, to reduce ear-strain and stress (now you know why pilots wear noise-cancelling headsets!)

Here's how:

1) Locate the dodosound.cfg in the low skid model sub-folder.

2) Open it with notepad (right-click and select "open with.." if you don't already associated .cfg files with a text editor, and select Notepad.exe.)

3) You see that each wav file has its own parameter block that will look something like this:

[ENGINE_N2.1.01]
filename=DodoSim_206_FSX_Transmission
flags=2
viewpoint=1
panning=0
rparams=0.00,0.2,0.5,0.6,1.400000,1.400000
vparams=0.0,0.0,0.05,25.0,0.15,50.0,0.55,75.0,1.4,100.0
insideConeAngle=360
outsideConeAngle=360
conePitch=0.000000
coneHeading=0.000000
outsideConeVolume=10000
full_Scale_Distance=60

4)  The line that starts "vparams" describes the sound volume as a percentage at several points within the driving variable's range, i.e.:

vparams=0.0,0.0,0.05,25.0,0.15,50.0,0.55,75.0,1.4,100.0

This line is made up of 5 pairs of values. The first in each pair is the point in the variable's range and the second is the relative sound volume.

So, the first pair, "0.0, 0.0" means that when the variable (which is N2 for the transmission sound) is zero, the sound volume is zero.  The last pair "1.4,100.0" means that when the N2 is overspeeding to 140%, the volume is 100% (maximum.)

5) To lower the volumes of any sound, reduce the value of every second parameter by a suitable factor. i.e. To reduce the volume of the transmission whine by half throughout the whole N2 range, the line would look like:

vparams=0.0,0.0,0.05,12.5,0.15,25.0,0.55,37.5,1.4,50.0

Note that values less than 0% or greater than 100% are limited to those values.

6) Save the file and reload the aircraft.

**Always make sure you've backed up the original dodosound.cfg before you make any changes to it! **

------------- Info for people familiar with sound.cfg files -----------

People familiar with FS sound.cfg files will notice some new additions to the dodosound.cfg.  Although the file structure looks like the standard sound.cfg file, it is actually read by our custom programming and not the FS sound engine.  The file structure was designed in this way to make it more understandable to people familiar with FS sound.cfg files who wanted to customise it themselves.

Some things of note:

1) rparams and vparams can have a maximum of 16 points, rather than the FS default of 8 per sound.

2) Driver variables can exceed 1.0.  1.0 is used to represent the 100% mark on a gauge, such as rotor speed.  Since our code allows the rotor to overspeed, we can handle variable values up to 1.4 (140% NR).

3) Due to a limitation in FSX's SimConnect (or any other) interface, it is not possible to get the view distance and angle on the aircraft.  For that reason, we could not replace the external sounds in the same way as we did the internal sounds.  

Instead, we can play internal sounds in external views but at a different volume. However, this volume will be the same irrespective of how far the viewer is from the aircraft.

The line "viewpoint=" determines which views the sounds play in as default, where 1 is internal and 2 is external.  However, we add the value 3, which means both.  

If the viewpoint=3 then there should be a line in the block that reads something like "viewpointAttenuations=0.0,80.0".  This tells our sound engine by what percentage to reduce the sound volume in the internal and external view respectively.

So "viewpointAttenuations=0.0,80.0" means: don't reduce the sound volume in the cockpit, but reduce it by 80% in external views.

4)  Note that because the SDK does not provide view distance and aspect angles, the 3D sound information lines, like cone angles in the dodosound.cfg have no effect.  (Since you are effectively surrounded by overwhelmning sound in a cockpit anyway, internal 3D sounds are largely irrelevant anyway.)

5)  We have added additional sound block types, these are:

[IGNITER]  - This is for the tick-tick of the spark igniter
[ENG_OUT]  - This is for the engine out warning horn
[ROTOR_LOW]  - This is for the NR low warning horn when collective is off the bottom stop.
[CLICK_ON]  - Switch click sound going one way.
[CLICK_OFF]  - Switch click sound going the other way.
[ENGINE_DAMAGE]  - Grinding sound when engine is destroyed.  Is linked to N1 speed.
[MAIN_TRANSMISSION_DAMAGE]  - Grinding sound when main transmission is destroyed.  Is linked to N2 speed.
[TAIL_TRANSMISSION_DAMAGE]  - Grinding sound when tail rotor gearbox is destroyed.  Is linked to N2 speed.
[ROTOR_JUDDER]  - Plays when rotor is oversped significantly or VRS is entered.
[TRANSMISSION_WHINE]  - Winding sound that plays when clutch is disengaged and the rotor is under stress, i.e. when airflow overspeeds the rotor or clutch is disengaged during an auto.  Plays according to the difference between NR and N2 and absolute NR.
[BLADE_SLAP]  - Plays when the airflow changes significantly through the rotor or when flying in the noise abatement region. Varies in freq according to NR.

--------------------------------------

We hope this helps people tailor the sounds to their liking.  However, please ensure you backup the original dodosim.cfg.  Should you request support from DodoSim regarding sound issues, please mention in the request that you have edited the file as this may be very relevant to your problem.

For user friendliness, any chance that individual sound settings be done through the Dodosim menu within FSX?

Not beyond the sliders that we have already implemented for specific volumes.

No, but I can add one for you.  :)

Thanks for adding the Rotor Brake section in SP1. I've made a wav file to use, so I need to play around with the params to get something working.

Can I get the sound section to run by simply having the battery on and selecting the rotor brake, or will I have to go through the entire start up shutdown routine to get the sound section to activate until I figure out the params needed?

I've just bought the 206 FSX and I could only hear very soft rotor sound from external view. Cockpit sound was okay though. When I turn on my speaker volume to hear the external sound, the cockpit sound became a blast.

I've read the above steps but am not able to follow it. Is there a easier way around? All I want is to have internal and external sound to be of about the same proportion in strength.

Thanks.

Just go into the Settings dialog under the Add-Ons->Dodosim menu and lower the sliders to match your expectations when compared to the external sound and then adjust your speaker volume to your taste.

Hi Simon.

Waths the max vol, cant i set in this item.

[IGNITER]  - This is for the tick-tick of the spark igniter

by default is 8000, and  its realy low for my. Im set in 12000 and no change the vol.......????

Please, help me........................jejeje

Hi,

Well I was on the fence about getting this for a while now but I finally sprung for it since I am set up so well to fly copters on my rig.  Am I glad I got it, what a blast.  I am even landing on setting 5 now after crashing for a couple of days :).  The package is very well done and I highly recomend it if you like flying helos.  Just don't give up on it as at one point I even had these very pretty flames shooting out my exhaust, lol but kept at it.  BTW, I highly recomend setting fire to your engines at least once as it really is wonderful site to see at least one time ;).

My biggest recomdation would be to supply an alternative dodosound.cfg that would imitate what you would hear in the cockpit while wearing ear protection, my ears and neighbors wold both thank you for that.  Dreamfleet did something similar years ago where you could switch on the fly from wearing a headset or not.  I really liked that feature as it allowed you to hear the aircraft sounds at full volume while quieting things down in flight so you could hear ATC.  At least an alternative cfg file to manually activate would be appreciated, also.

Thanks for the great package, I'm having a blast.

Swapping out the sounds for a different set would be reasonably easy to do.  You cold just (back up the originals) and then use a sound editor to pass them all through a low pass filter plus knock the volumes down a bit.  Any sounds played in the external view would also be muffled though.  (At least as far as the custom Dodosound.cfg sounds.)

Making them switch on the fly would require us to change the software and I don't know how well it would work under Windows Vista and 7, due to changes in how the OS handles sounds.  (There are no end of strange DirectSound quirks with FSX under these OS's.)  It would also require twice the number of sounds to be loaded at the same time to provide a fluid switchover, and that may well cause PCI bus loading problems for some users, resulting in crackling and other artifacts.

Hi Simon,

It was just an idea, I am loving this package.  I have been playing around with the dodosound.cfg tweaking it and I like what I have so far.  There is one sound that I can't put my finger on and would like to make one last adjustment by turning it down a bit.  It's a background sound in the cabin that modulates up and down and is not the jet or transmission.   I was hoping you could point to a possible line in the cfg that I could work with to make the adjustment.  My first guess was that it was the reverb but I made an adjustment to that line and I did not notice much of a difference.  BTW. the reason I just don't turn the volume down is because I am trying to keep some of the other sounds intact (like the blade slap) while tweaking down the ones that are a ringing in my ears (like the transmission).

I need to go fly this thing some more :).

Later,
LouP

It's probably either the N1 or transmission as they modulated according to power. Reverb is just the warbling exhaust stack at initial light-off and 33% N1.

It would be a great addition...emulating noise cancelling headphones.  If you thought you had a problem, you could 'turn them off' briefly while you listened...then turn them back on to protect your hearing while you dealt with it..or not.

Dodo is all I fly....fantastic job.

G'day from downunder, please an easy fix to hear ATC louder. Love my dodosim 99% of what I fly. FTX blue, Newport Adelaide metro and dodo that's it.
