I have a Digi2 Pro with DSP add-on, and I am running optical out to my headphone DAC/amp.
I would like to set specific frequencies and Q factors within the DSP, as shown below:
(this is a published Harman Preferred Listening Curve EQ filter for my HD600 headphones)
|Peaking||25 Hz||0.88||6.3 dB|
|Peaking||3227 Hz||3.43||-2.5 dB|
|Peaking||4190 Hz||6.2||3.7 dB|
|Peaking||9702 Hz||1.43||3.3 dB|
|Peaking||19499 Hz||0.42||-11.3 dB|
|Peaking||60 Hz||2.11||1.0 dB|
|Peaking||180 Hz||0.86||-1.9 dB|
|Peaking||573 Hz||1.18||1.1 dB|
|Peaking||5959 Hz||5.4||-3.9 dB|
|Peaking||6591 Hz||2.48||2.0 dB|
The web-UI for the built-in HiFiiBerry EQ tool is nice, but I can only set frequency in increments of 100Hz on the higher end.
What is the easiest way for me to set more specific frequencies?
