Cross-Talking Stereo ITD/ILD Tester

Sitting in remote meetings all day long I’m regularly wondering: Why is it so much harder separating voices from different participants if they cross talk than in a meeting room. I knew from university that we can identify where a sound comes from simply by utilizing delay and volume differences between the ears. Then I thought: That might make the difference and it sounds like something you can solve with software. I drafted a prototype with some AI tooling and was surprised how well it worked. I found out that Zoom has some kind of feature like this that they patented. It is in combination with the position of the video AFAIK. That’s where I stopped working on this. I’m not a patent expert, but I still think it is a fun demo and maybe something that is integrated into video call software everywhere.

Fast Physarum Simulation in the Browser with WebGL2

In 2021 I found this cool slime mold Physarum simulation, where particles formed organic patterns by following trails left by others and I was hooked. It looked mesmerizing and it somehow felt like time to build a neat simulation again.

In my past, I built many simulations and visualizations. Back then, this always involved using a framework and building an executable, usually in C/C++. This was okay if you wanted to run it on your own machine, but it made sharing with others a hassle. You don’t just send around executables, and most people don’t want to bother with compiling code themselves.
