Datasheet DSP Add-on board

Overview

The HiFiBerry DSP add-on board is a board that allows to extend some HiFiBerry boards with a Digital Signal Processor for audio processing. The DSP can be programmed via Analog’s Sigma Studio or be used with pre-defined DSP programs.

Facts

  • 300 MHz Digital Signal Processor (6144 instructions per sample incl. FFT and FIR accelerators)
  • High quality asynchronous sample rate converter that can upsample/downsample/mix audio sources
  • Users can upload programs developed with Analog’s SigmaStudio
  • Connects to the DSP header of selected HiFiBerry sound cards
  • No soldering, comes as a pre-fabricated kit.
  • Directly powered from the Raspberry Pi, no additional power supply
