From the project
Guitar stereo multi-effects using RP2040
RP2040-DSP is a fully modular 24-bit stereo audio effects processor built on the Raspberry Pi RP2040 microcontroller. It is designed to run real-time audio effects for guitar and other instruments, including cabinet simulation for headphone or direct recording use.
The firmware architecture is modular, supporting multiple effects that can be stacked and configured flexibly.
