I don’t think the software is there as of this latest release. You may want to submit this as a "Suggest a New Feature" request.
So far I’ve only submitted two request but I’m sure that I'll be adding more soon.
The following are the two request’s that I have submitted:
1. For a provision to display the room response showing any automatic PEQ correction (if any) applied after all calibrations have completed. Also with the ability to auto-correct AND manually PEQ correct the room response.
2. For a provision in Volumio on the Pre-8 to allow installation plug-ins for the Volumio plug-in store.
As for the first request, if you have ever used the legacy DEQX-Cal, it has this feature. What was nice about it, is that it did have the Auto-Correct feature which by default would apply PEQ correction very conservatively. It gave you a great starting point and from there you tweak those setting or change it up completely. It applied the updates in real time where you could immediately hear any change. Right now as it stands, you cannot visualize room response at all. I assume that room response measurements are taken and adjusted automatically in step 3 of the calibration sequence.
The second request is asking for a feature at all other implementations of Volumio already have. Hopefully the Volumio folks can code this one for DEQX so that can keep working on enhancing the core product’s software.
