HiFiBerry DSP Add-on
The HiFiBerry DSP add-on board extends some HiFiBerry Raspberry Pi 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.
The DSP add-on board adds digital signal processing capabilities to the following HiFiBerry sound cards:
- DAC2 HD
- DAC2 Pro
- DigiPro 2
- Amp3
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.
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
