[Mack Anthem] Audio Pop in Loaded Engine Sound [115739]

#1 Post by supersobes » 30 Apr 2020 15:29

While driving the Mack Anthem, I noticed an audio pop in the engine sound about every four to five seconds. I also noticed that it only happened when either the driver is pushing the accelerator or the cruise control is causing the truck to accelerate. I opened up the FMOD bank for the truck, and I found that in the sound file titled "loaded_xx," there is an audio pop about half way though the sound sample. I've attached two videos to this report; the first one demonstrates the truck driving down the highway in which you can hear the audio pop as well as the truck slowing to a stop to show that it only happens when the accelerator is applied, and the second video shows the "loaded_xx" sound sample being played.

Yeah I've noticed it too. It's rather annoying.

Now this is one kind of a bug I've been told about before, but I was never really able to hear it to be able to pin-point it as you did, Sobes! Good work! Thanks for your report! :) QA 115739

I'm not hearing any pop other than the engine itself. It must be at a frequency I can't hear.

That was initially my problem as well, but after I saw supersobes's video with the sound file only, I could finally hear the problem.

I don't know what audio setup you guys are using, but I can hear it best when using headphones.

I'm still not hearing the pop on my computer speakers (Logitech THX certified speakers). I do know I have high frequency hearing loss above 16kHz, so maybe that's why

I'm still experiencing the popping in the Mack engine sound on version 1.39.3.3. Is there a possibility that this issue can be fixed soon?
