Today I met the one and only Mr. T—and instantly turned back into a 13-year-old A-Team fan! 🥹🔥📺 The whole thing was mind-blowing. I was driving by Dawson Technical, saw the mural on the wall, and thought, “That’s so dope!” 🎨🙌🏾 I stopped to take a picture, walked inside—and there was Mr. T, walking right toward me! 😲🤯Divine timing! ✨ What an honor to meet this brother and see his passion for our people and our community. ❤️✊🏾 We should celebrate our heroes while they’re here. I feel incredibly fortunate our paths crossed today while he was out doing his civic duty and voting. 🗳️🇺🇸 That’s DOPE! 💥 Stay focused, positive, and productive. ✨💪🏾 Peace! ☮️✌🏾 @Precise_Chi

Today October 27th marks the great city of Philadelphia’s 344th birthday, founded by William Penn on this day in 1682 Happy Birthday, Philly. Thanks for letting me be here to witness and capture a tiny little part of your story You could live anywhere but you live in Philadelphia, the best city in the world🔔🫶💕

THANK YOU to @Twitch for featuring me on the front page today. What an awesome surprise. Much love to everyone who tuned in, especially those who discovered my channel for the first time.

People are asking “why did old music sound fatter than new music?” Magnetic tape. The compression of magnetic tape automatically boosts two frequency ranges but it does it in an extremely beautiful way rather than applying it in post on purpose digitally. There’s also an element of the vibrations, frequency and energy of the music warping the tape itself. This is one reason why a lot of Hendrix music sounds electric and other guitarists couldn’t emulate it.

Keep pushing. major improvements, on a daily basis. 0.1.57 will be shipped soon. Again leveraging your existing GPU instead of consuming credits - this time for upscaling. Stay tuned.

Like and retweet today (10/16) to be entered to win this gamepad. This is the first fully home-serviceable / home buildable version of the design. A proof of concept for an eventual “print your own” kit. This is fully built by yours truely and ready to go!

JUST IN🚨: We may have miscounted Earth's population.... by literally billions, new study reveals.

BOOM! Well, I'll be damned if that's not the very BEST-sounding, 100% simulated/synthesized concert grand piano I've ever heard! FrankenSim.org/music What does that mean? ZERO recordings of real-world sounds were used (other than for comparison and diagnosis), nor were any measurements captured by microphones or similar. Literally everything from start to finish here was part of an enormously intricate physics simulation of a piano: its geometry, materials, moving parts, and acoustic radiation. Oh, and I did the same thing for a full drum kit and cymbals. The cymbals are modelled using the estimated geometry and dimpling pattern of a real Zildjian splash cymbal, together with estimated profile details and literature-based properties for B20 bronze alloy. For the most extreme audio quality, you can pre-render to WAV files or similar. But after many, many rounds of iterative performance optimization, I now have the wasm version running at better than real-time, so it sounds really good live in the browser as well! This is a big deal. It's shockingly hard to get truly realistic-sounding audio from synthesized instruments. The real world is just too complicated. What people usually end up doing is spending hundreds or thousands of dollars to buy these massive libraries of recorded sounds of a real piano, which takes up many gigs of space and is super slow to use. The worst part of that approach isn't the size of the files, the cost of the sample packs, or the inelegance of the approach. It's that EVEN THAT is a massive simplification, because they are recording each key separately at various key velocities and so forth. That means they are missing the very complex interaction effects that arise in a real piano when you play certain keys at the same time or after one another. The energy persists in the instrument and conditions the next sounds. It's subtle but real and you pick up on it when it's missing. And yes, they do try to capture some of this, but they use very lossy methods with more simplified approximations that are way more primitive than what I'm doing here with FrankenSim. I've invested a massive amount of time and focus on ensuring that the energy accounting is correct in these simulations. And the same thing goes for drums! There are complex interaction effects. These sorts of things are emergent and "just fall out" when everything is simulated for REAL using the actual underlying physics. So why haven't other companies and people done this? I'm not actually sure; it's kind of insane when you consider all those people working at Yamaha, Roland, Korg, Moog, etc. But my guess is that it's because it's super hard and complicated to get all the physics right and to program it the right way so that it's tractable without needing crazy amounts of compute. Anyway, take a look at this demo site I set up. It's a lot of fun to play with, and at the bottom there is a nifty MIDI player that takes any MIDI file and lets you listen to it with the high-quality simulated piano and drums in the browser. This is the culmination of months of work and hundreds of billions of frontier tokens. It all started when I wanted to see what Fable 5 could really do, so I thought of the most comically ambitious project I could think of: FrankenSim, the system that unifies ALL of physics into a single coherent and cohesive simulation across all domains: mechanics, fluid dynamics, electricity and magnetism, etc., instead of modeling each domain as a separate silo, where each domain can use the same generic geometric primitives, solvers, calculus machinery, etc. All unified using the language of sheaf cohomology to maintain consistency between representations, and where everything is made as legible, intuitive, and ergonomic to AI agents as possible. This music simulation stuff is just the beginning. Beyond many more instruments, I'm going to be using FrankenSim to model HVAC systems, fluid flow through plumbing systems, and more!
