1. Do you need support for Assetto Corsa Competizione? Please use the proper forum below and ALWAYS zip and attach the WHOLE "Logs" folder in your c:\users\*youruser*\AppData\Local\AC2\Saved. The "AppData" folder is hidden by default, check "Hidden items" in your Windows view properties. If you report a crash, ALWAYS zip and attach the WHOLE "Crashes" folder in the same directory. Do not post "I have the same issue" in an existing thread with a game crash, always open your own thread. Do not PM developers and staff members for personal troubleshooting and support.
  2. When reporting an issue with saved games, please always zip and attach your entire User/Documents/Assetto Corsa Competizione/Savegame folder, along with the logs and the crash folder (when reporting related to a crash).
  3. If ACC doesn't start with an error or the executable is missing, please add your entire Steam directory to the exceptions in your antivirus software, run a Steam integrity check or reinstall the game altogether. Make sure you add the User/Documents/Assetto Corsa Competizione folder to your antivirus/Defender exceptions and exclude it from any file sharing app (GDrive, OneDrive or Dropbox)! The Corsair iCue software is also known to conflict with Input Device initialization, if the game does not start up and you have such devices, please try disabling the iCue software and try again. [file:unknown] [line: 95] secure crt: invalid error is a sign of antivirus interference, while [Pak chunk signing mismatch on chunk] indicates a corrupted installation that requires game file verification.

Sound Simulation?

    A lot of sim chat and discussion seems invested in the physics modeling of a car and how it impacts the feel of a vehicle. Yet i rarely see too much casual discussion about audio and related modeling.

    How does/did Kunos capture/create sound for AC's officially licensed cars?

    No doubt some are educated guesses (one of a kind historical cars), or with approximations? Yet for currently manufactured race and road vehicles how does Kunos capture it?

    Is the sound we hear intended to be the sound within a vehicle without or with a helmet on?

    For the most part they record sounds from all around the real car, I've seen pictures of them doing it. I think for the most part they had access to the real cars too.

    They recorded inside the car and outside, I'd guess the helmet didn't come into it.

    Perhaps adding more to realism than the actual fidelity of the recordings is that sounds are actually played when they should be. For instance skids sound do match according to the level of skidding during corners, braking and acceleration.

    I suspect engine load plays a factor on the engine sound as well. An engine running at 5,000 rpm with no load (clutch open) would not sound the same as an engine fighting full acceleration at the same 5,000 rpm. If they only record the engine sound with an unloaded engine, we might be missing something.

    Another aspect could be whether the sounds play from the correct speaker on a surround system. E.g. rear speakers on a rear engine car, etc.

    In general I'm happy with AC's sounds, this is coming with someone with 2.1 speakers though. I do wonder if more can be done in terms in realism.

    I'd prefer they not attempt to represent muffled sounds heard while wearing a helmet; for those that want that, it's easy enough to filter the audio for such effects. Pcars had that feature in Helmet cam and they eventually added the ability to switch it off due to many complaints from players.

    There are some titles that do a good job of creating Engine-Load effects with increased intensity in intake and exhaust sounds; iRacing comes to mind.

    A title that has very nice tire sounds is Automobilista; despite it's sound-engine limitations, it's pretty easy to tell what tire is locking or at the threshold of grip-loss.

    Perhas, indeed. However the intended question i note in the OP here is more ... I rather wonder how Kunos go about capturing or creating sound for AC. How long does it take? Are there any particular software tools or mics used? What is the technical goal when KS's audio dev's start crafting the audio experience of a vehicle? How are the different effects we hear created for the different sounds a car can make in AC. Be it the engine, tires, etc.

    I wouldnt mind knowing how they do it, but even if the sounds were 100% genuine, eveyone will get a different experience because of the speakers they use. Even if you spent a couple of thousand dollars on speakers you may not get anywhere near the real sound depending on the quality of the speakers and the amp subwoofer etc.
