cannot reproduce Different sounds between engine 1 and 2 when Idle/AB

[TheGoose]

Hi,

I noticed different engine sounds during flight. Engine 1 idle, engine 2 at AB and vice versa.
Same on ground

SOrry not seeing this, by chance are you running any mods, specifically sound mods?

[TheGoose]

Sorry no mods active

[TheGoose]

I did make a video where you clearly can hear the difference.

@NineLine could you check the video, anything I could do on my side?

[NineLine]

Can you include a track as well please, thanks!

@NineLine Its just a short one, ground hot start, left engine AB, right idle and vice versa.

Still different

@NineLine could you find time to check the track file?

Just noticed the same issue last night.  

It seems like engine no. 1 one has a fuller sound model (turbine whine, combustion, and, with the sound of massive amounts of air being compressed and moved).   While engine no. 2 only generates a quiet turbine sound.   
 

Both engines combined sound great, but not so much when you have an engine failure (confusing auditory feedback)

The 2 engine's sound difference is very obvious. Maybe it depends on settings. I have always "hear like in helmet" turned on and "loud AB" turned off for most realistic sounds.

[Cgjunk2]

Good point regarding settings.  In my case, hear in helmet and loud AB are both off.   I hear the different sounds in each engine

I’m still experiencing differing left and right engine volume (or“soundscapes”) after the latest update.   Have the track files in this thread been investigated yet?  

edit: I don’t have any mods on my DCS install.

There could be a good audio mixing reason for different engine tones - if the sounds were identical then maybe they start interfering with each other causing a flanging/phasing effect?

That's reasonable but the current difference is huge!

Phasing effects happen in real life with multi-engine aircraft, so there shouldn’t really be any reason to want to eliminate the possibility of that occurring in a simulation.  It’s natural consequence of having two identical engines turning at nearly the same speed.  The phasing harmonics go away easily by simply running them at exactly the same speed.  
 

In any case, it basically sounds like part of the sounds are missing on the right engine.  Not sure why this thread is marked as “cannot reproduce”, unless only some of us are experiencing engine sound differences, but others are not.   If that’s the case, I’d like to find out how to fix it.
