New filter types

A family of first-order filters has been added:

  • All-pass for phase correction
  • Low and high shelf for gentle, broad tonal adjustments
  • Low-pass and high-pass slopes for crossover bands

On the RP2350, the first-order filters now share the same hybrid SVF/biquad design as the higher-order filters, giving them greater numerical precision at low frequencies.

Testing

A new hardware audio-loopback test suite validates the full signal chain end to end, including dynamics, crossover frequency response, output-stage controls, and channel alignment and latency stability.
