"Hi HN, I'm Mario, a full-stack developer. I built this 100% free, no-install web tool (using Python/FastAPI and FFmpeg) to simplify professional audio tasks for creators and small teams. I was frustrated by expensive, clunky desktop apps, so I focused on advanced features like a seamless multitrack mixer with crossfades, universal video-to-audio extraction (from URLs like YouTube), and robust conversion for challenging formats like WhatsApp OPUS/AMR. It's designed for efficiency in fast-paced production environments. Happy to answer any questions!"

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…
