So I could get my (1) room/ears done with someone else's gear (borrow or visit), and combine my (2) headphones/amp/ears with it, and discard my own room/ears portion to integrate their better room?
In fact, you don't need to do both parts of the calibration process all the time. You can just do one, and save the file for future use in multiple preset combinations. Then whenever you want you can combine that (or any) file of one type with any one file of the other type to produce a new preset.
And yes, that is the whole idea... to do your own headphone/amp/ear calibration (which does NOT use any loudspeakers or room acoustics completely separate from any room/ear calibrations. You only have the binaural microphones inserted in your ears and then you put on your headphones over the ears/mics, and then you perform the quick headphone/amp/ear EQ measurement). All that is measured is those components... not the room or loudspeakers.
Then you combine this one headphone/amp/ear file (assuming you only have one) with any number of room/ear calibrations done at other people's home or studio or store, to produce presets that reflect your headphone/amp equipment, your ears, and each of those other room/ear listening environments.
|I am assuming that using someone else's room/ears or headphone/ears profile will sound wrong, but just how wrong will it sound?|
I did this "use someone else's file" experiment back last year, and it was bizarre. With my files sound was directional, properly elevated and left/right oriented, etc., whereas with the other person's files the whole directionality got skewed. Not just elevated or rotated, but even "diagonally distorted". I know this seems hard to believe, but that's what happened.
There's clearly more to the SVS processing than a standard DSP hardware chip from TI.
