[CNX-Software] - DSPi firmware turns Raspberry Pi RP2040/RP2350 into a USB sound card with an onboard DSP engine

DSPi is a full-featured audio DSP firmware for the Raspberry Pi Pico, Pico 2, and other Raspberry Pi RP2040/RP2350 boards, which turns them into a USB sound card with an integrated DSP. It allows users to make use of essential tools like room correction, active crossovers, parametric EQ, time alignment, and more, and essentially works as a regular sound card on your computer. DSPi firmware’s capabilities: Dual-Core DSP – EQ processing is split across both cores on both RP2040 and RP2350. USB Audio Interface – Supports 16-bit and 24-bit PCM input at 44.1, 48, and 96 kHz, working on macOS, Windows, Linux, and iOS. S/PDIF Input – 24-bit PCM stereo audio at 44.1 or 48kHz. 24-bit S/PDIF or I2S Outputs – Up to 4x independent stereo output slots (8x channels on RP2350, 4x channels on RP2040). Subwoofer Output – Dedicated mono PDM output channel with a high-performance 2nd-order delta-sigma modulator, [...]
