Bucic Posted August 26, 2024 Posted August 26, 2024 This has been bugging me for many years now. With many improvements done in the field of soundscape in DCS this sticks like a sore thumb. Basically, when using e.g. the F3 view the sound frequency sharply increases close to the camera which isn't backed by any phenomenon I'm aware of. The more simplistic the sound set, the more pronounced the issue. IIRC it can even be hear with vehicles passing by the camera. A placeholder example https://youtu.be/BcbXvAzie5I?t=195 References: https://phys.libretexts.org/Bookshelves/University_Physics/University_Physics_(OpenStax)/Book%3A_University_Physics_I_-_Mechanics_Sound_Oscillations_and_Waves_(OpenStax)/17%3A_Sound/17.08%3A_The_Doppler_Effect There's another issue where the pitching up of external sounds goes completely crazy in some F5 view + lock combinations but let's leave it to a separate entry.

Bucic Posted March 2 Author Posted March 2 I'm not sure what's your interpretation of that spectrogram is. From my experience the frequency in DCS rises momentarily when the source passes the observer which I don't think is grounded in physics. For future reference: https://www.audiokinetic.com/en/blog/create-a-doppler-effect-with-wwise/ As you can see WWISE gives developers freedom in designing the effect. For good and for worse. I'll try to focus on capturing another bug that is directly related. Frequency rises by a very large degree with no increase in closure velocity. Usually can be triggered by using F5 camera and altering angles.

ED Team c0ff Posted March 20 ED Team Posted March 20 Most probably the virtual camera reports invalid veloicity value, which makes the sound engine to apply an unnecessary Doppler shift.

FYI we don't use WWISE. Hi c0ff! Long time no see! The possibility of wrong velocity reporting would coincide with some occurrences during dynamic F5 camera alterations involving the use of numpad arrows. Are you planning on investigating it further or do you prefer some more solid case to be presented first? I wouldn't like to push it over to your side of the carpet but I'm pretty illiterate as far as game audio goes. May I ask what is the actual current audio pipeline in DCS? Up to today I was under the impression that unless a game developer boasts about a specific audio API it's always WWISE otherswise. 1 F-5E simpit cockpit dimensions and flight controls Kill the Bloom - shader glow mod Poor audio Doppler effect in DCS [bug] Trees - huge performance hit especially up close

Oh, that's interesting. Another bespoke implementation in DCS then. Let me take the opportunity to thank you and the whole DCS audio team for the improvements you've made to DCS. The audio engine rewrite in the Black Shark 1 times was promising but then the updates stalled somewhat (the rewrite got scrapped for a better implementation that we have now?). Sometime later the improvements really picked up the pace! Warbirds finally sound like proper piston engine beasts, the jets got atmospheric distortions as part of a general overhaul, cannon employment doppler effects are epic, Dora sounds so good I can spend an evening just taxiing with an open canopy... And the AH-64D audio! https://www.youtube.com/watch?v=2ZXyh8NTu1E https://www.youtube.com/watch?v=wdCB0VoHvpo If you have the time please give the following a look as well: [Audio] Afterburner only audible in rear hemisphere [Audio] volume of sonic boom deafening despite low World slider setting F-5E specific [Audio] Sidewinder volume knob doesn't silence the tone completely 1 F-5E simpit cockpit dimensions and flight controls Kill the Bloom - shader glow mod Poor audio Doppler effect in DCS [bug] Trees - huge performance hit especially up close
Bucic Posted May 23 Author Posted May 23 (edited) Just a thought Haven't the Echo 19 guys already solve it? Take a look https://youtu.be/vHZ62udcFhs?t=140 https://youtu.be/vHZ62udcFhs?t=349 They might have, or they just supress the effects that make the wrong behavior clearly audible in the stock version.
