Based on our work with BeoCreate, this DSP Add-On module enables the application of filters for room and/or speaker correction while still in the digital domain, rather than downstream after conversion where noise and distortion can be introduced in the Analog format. These modules only work with our ‘2' series boards, such as DAC2 HD and DAC2 Pro. Programming is directly supported in HiFiBerryOS, with other distributions you will need to install DSP toolkit to program the DSP.
