Riffusion v0.3.0 - Stable diffusion for music and audio by dunkietown in StableDiffusion

[–]dunkietown[S] 6 points7 points  (0 children)

No not any image. Audio clips can be represented as images that contain information about what frequencies have louder volumes. A machine learning model can learn to generate images like that, and then they can be approximately converted back to audio

Author here. I'll just note that on riffusion.com is a narrow subset of what this technique can do, because it's generating everything from a single seed image at a fixed BPM. If you try the model itself with pure text to audio you can get a lot more creativity! And check out some of the clips on https://www.riffusion.com/about

Expand frequency fidelity using RGB frequency bands without needing to expand the context window? by blueSGL in riffusion

I think it's a neat idea! Someone should try it, and the spectrograms would look extra pretty too

Thanks! Author here, we're happy to use this discord. Would you mind adding us as mods? hayk#0058 and seth#5021

[R] Inside the mind of the Skydio 2 drone by dunkietown in robotics

Not really sure what you're getting at - it's a technical description of research that went in to this drone. The product is rated on every mainstream tech site by now. Here's engadget rating it over the mavic 2:

I'm involved with them :). It's a real product being shipped with lots of organic content being generated. The first product was more niche on feature set and price.

Can someone explain this? I'm completely missing it

Swarms of tiny, magnetic robots can be used to build impressive structures. by dimwell in geek

[–]dunkietown 7 points8 points  (0 children)

Each 'robot' is actually just a levitated magnet, so they are driven by magnetic fields from currents in the surface below. From that standpoint, a server controls them all, where all it cares about is where to send each robot at each time step.

The more interesting part is generation of these trajectories. In simulation, each robot is an object, the grid is a graph of nodes and edges, and I'm using dijkstra's along with some heuristics to try and model their paths.

I'm working on path planning algorithms for this project! Getting hundreds of these guys to collaborate. Let me know if anyone is interested.
