We ran into a couple snags on the user interface but we are back on track.
Here is the current interface.
It works like a charm but we need to optimize some of the circuit behavior.
Current supported features:
Low Pass Filter: 24db/octave Q=0.707 Variable from 40Hz-200Hz.
Gain: -60db -- +6db
Subsonic Filter: 12db/octave Q = 0.707 Variable from 8Hz-50Hz
Four bands PEQ: 0--30db cut, 1/12th -- 1/1 Octave Q, variable from 10Hz-200Hz.
Linkwitz Transform: Currently we have two. We had some extra resources and I'll probably hide one of them in the shipping version.
The room measurement is done via swept sine wave, takes about 2-3 minutes. The room response shows up in the window and you can make adjustments to the electrical filters, seeing the resulting acoustic response due to filter changes. You can save and upload different filter profiles also.
Overall we are making progress.
