Hifiberry DAC+ DSP Digital-to-Analogue Converter for Raspberry Pi

Hifiberry DAC+ DSP Digital-to-Analogue Converter is an add-on board for Raspberry Pi that combines a 24-bit/192kHz Burr-Brown digital-to-analogue converter with a 300MHz digital signal processor in one unit.

Overview

The board's Burr-Brown converter supports 24-bit/192kHz audio and provides stereo analogue output through gold-plated RCA connectors. The 300MHz digital signal processor is capable of 6144 instructions per sample and includes FFT and FIR accelerators for complex real-time audio processing. With a Raspberry Pi, the board can be used as a high-fidelity music streamer, or it can operate as a standalone audio processing unit.

Key Features

• Burr-Brown DAC with 24-bit/192kHz resolution
• Stereo analogue output via gold-plated RCA connectors
• 300MHz digital signal processor with 6144 instructions per sample
• FFT and FIR accelerators for complex audio processing
• Digital audio input up to 96kHz and output up to 192kHz
• Asynchronous sample rate converter for upsampling, downsampling, and mixing different audio sources
• Onboard EEPROM allows the board to boot and function independently of the Raspberry Pi
• Supports custom audio programs developed with Analog Devices' SigmaStudio graphical development tool

Applications

The board is suited to multi-room audio systems, room equalisation, digital audio effects, and custom audio projects. Its digital signal processor supports tasks such as equalisation, filtering, and mixing, and the onboard EEPROM supports dedicated equalisation applications.

Dimensions and Weight

The board measures 2.6 (width) x 1.35 (depth) x 3.65 (height) and weighs 38 g.
