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)
| Type | Fc | Q | Gain |
|---|---|---|---|
| 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?
Thanks
