Got something totally different, but exceptionally badass today to share! Here is a bunch of direct hardware captures of the (F)ixed (F)unction and (F)ast (F)ourier (T)ransform (T)esting audio visualization demos, running on my Sega Dreamcast! github.com/meisei4/fffftt This incredible piece of science, engineering, art, and music started off as a crazy idea to port a bunch of GPU-based, Shadertoy audiovisual demos to the Sega Dreamcast, to play with combined digital signal processing and rendering on legacy fixed-function hardware. As you can see from the video, the FFFFTT repo includes a wide array of different demos, each providing different kinds of visualizations, each featuring different types of signal transformations and analyses, with many of them also being interactive, all done in real-time! Not only that, but you ALSO can freaking pause the playback and analyze the signals in real-time... crazy! The final resulting FFFFTT demos are an epic full-stack conglomeration of @raysan5's raylib, providing the backing infrastructure and graphics framework, which sits atop our GLdc driver for rendering, using @mackron's miniaudio library for sound playback, with its FFT and vector algebra accelerated for the SH4 CPU using my SH4ZAM math library... all ontop of KallistiOS, running on the Sega Dreamcast! Congratulations to @U_REI_0 for the fantastic accomplishments, and a heart-felt thanks from me for bringing everything together to make this happen! You just laid the framework for some epic audio-based gameplay mechanics and other crazy science experiments in the future for whole community!
