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 Resources * Datasheet * HiFiBerryOS Filter Designer * DSP Toolkit https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2023-03-07 https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2023-11-06 https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2023-12-27 https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2024-09-19 https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2024-10-09 https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2024-11-29 https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2024-11-30 https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2025-02-24 https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2025-07-10 https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2025-11-28 https://elecena.pl/product/22720151/hifiberry-dsp-add-on 2025-11-29
