I have just received my DAC + DSP. Congratulations on introducing a wonderful addition to the HiFiBerry product lineup.
I am using an RPi 3 Model A+ with HiFiBerryOS 20190131.
Before applying a filter .txt file, referring to the REW-Basics guide, do I need to first install the profile at
dsptoolkit install-profile https://raw.githubusercontent.com/hifiberry/hifiberry-dsp/master/sample_files/xml/dacdsp-default.xml
Also, what directory is the filter.txt file copied into?
I copied my test filter file into /boot using scp but running
dsptoolkit apply-rew-filters reports file not found error 21
I must have made a newbie error somewhere. Any help from the team would be appreciated.
