DSPi is a fully featured audio DSP firmware that turns a Raspberry Pi Pico (RP2040) or Pico 2 (RP2350) into an inexpensive USB sound card with an onboard digital signal processing engine. It provides room correction, active crossovers, parametric EQ, time alignment, loudness compensation, and headphone crossfeed with S/PDIF and I2S outputs.
Use cases
- turn a Raspberry Pi Pico into a USB sound card with DSP
- build an active multi-way speaker crossover on a budget
- apply parametric EQ and room correction to USB audio
- add headphone crossfeed and loudness compensation to a listening setup
- route and mix USB audio channels to multiple I2S or S/PDIF DACs
- use a Pico as a cheap digital audio processor for hi-fi
When to choose
- you want a very low-cost, hackable audio DSP on RP2040/RP2350 hardware
- you need USB audio input with flexible matrix mixing and PEQ filtering
- you want plug-and-play USB audio on macOS, Windows, Linux, or iOS with onboard processing
When to avoid
- you need very high sample rates beyond 96 kHz or multichannel beyond 8 outputs
- you need a general-purpose desktop DSP running on a PC rather than embedded firmware
- you require proprietary codecs like Dolby or DTS decoding
