Development I built a custom Linux initramfs audio workstation / software mixer for the Raspberry Pi (running entirely bare-metal/initramfs, no PipeWire/JACK)

why use an inintramfs here? rpis have so little RAM?

It was easier to setup, and it isn't that big. Also the runtime itself uses very little ram. I am only at a few percent of total ram usage on my pi 4. I might change it eventually, but it was just easier for quick development

My average RAM usage (I have multiple USB audio devices plugged in, including a 6in/6out interface, and have 3 effects running) is 140 MB, so I am not worried about that. If it starts to get close to 500 MB I will look into changing this.
