Yes, it was released 2 months ago!

@@AngeTheGreat wow superb, thank you for the reply, signing up now!

@@AngeTheGreat I have just signed up to patreon and am on the discord, but cant see mention of the ES3D demo being released anywhere, am i missing something obvious haha?

@@barevids In the introduction video (pinned on Patreon) and in the instructions sent immediately after you join, it mentions that all releases are made on Discord

@mikeyangyang8816 No I didn't. Go back and watch it and then come back and delete your clearly incorrect comment. Since I doubt you'll do this, here's the exact quote from that video: "The pressure wave that is created in the exhaust system is sent directly to a separate thread that then converts it into an audio signal. The final audio signal consists of some plain white noise, some equalization and a filter which approximates the sound propagation pattern within the exhaust system. Here is a demonstration starting with the base pressure wave and ending with the final audio that you hear." Not only did I explicitly mention all audio processing steps, I SHOWED them in the video. Seriously, why lie and write a comment like this? I don't get it.

@@AngeTheGreat Sorry, I didn't find it. But I just wanted you to know that your videos gave me the impression of not having audio processing done other than the the sim itself. Me having a physics and a CS degrees feel that that is basically impossible to do. I am sorry for my errors, and I am biased. I also feel pretty jealous of you before I found out how you were actually doing it (using noise as the audio and work from there using algorithms), which made a lot more sense to me. However, I have to say that you impressed me, and your videos and projects are a great part of the internet.

The old version of Engine Simulator did require some very basic audio processing, but I was very upfront about this in all of my videos and the algorithms are all visible in the open-source repository on my GitHub. The quote I gave above is directly from the very first video on Engine Simulator verbatim. Some people believed that the sound was achieved mostly through audio processing, however, this is also not true. The output of the fluid simulation was augmented using very basic audio filtering to recover some lost higher frequencies (as I said in this video). The new version really does require no audio processing whatsoever. To make it even less ambiguous, there is nothing in the production of the sound that cannot be firmly identified as a real physical phenomenon and no real-life samples, audio clips, impulse responses or any other measured sound is required for the simulator. Only the tube geometries and other physical engine parameters. I appreciate you retracting your previous statement and hopefully all misunderstandings are now cleared up. Thanks for watching!

@@AngeTheGreat Thanks, that makes a lot more sense now. In the older version, I thought you were saying that you were only simulating pressure and temperature of air molecules to create the sound. If that were true you would need a high enough density of simulated molecules with interactions to make physical sense (these types of simulations don't use thermodynamics algorithms). But I saw you were here rolling your own simulation in real-time on one thread was just too much for me to handle. These fluid simulation typically take anywhere from a day to few weeks to compile the final outputs on a supercomputer. One of the classes I took used supercomputers to do some calculation, and the engineers there said they were simulation air through molecules model and were using it to validate some old equation. I guess this is why differential equations is there, even though it is a bitch to learn. Thank you for your videos.
