HiFiBerry DSP Add-on

The HiFiBerry DSP add-on board extends some HiFiBerry HATs for Raspberry Pi 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. The DSP add-on board adds digital signal processing capabilities to the following HiFiBerry sound cards:

* DAC2 HD

* DAC2 Pro

* DAC2 ADC Pro

* Digi2 Pro

* Amp4

* Amp4 Pro

It is directly supported in HiFiBerryOS, with other distributions, you will need to install the DSP toolkit to program the DSP. Please note:

* This board cannot be used standalone - one of the above HATs are required.

* The board will only fit the V2 Steel case when used in conjunction with the DSP mounting kit.

* Fits just fine in the newer universal case for Pi 5 and universal case for Pi 4

Features

* 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
