Null Tests

[KingsXJJ]

If you take a listen to Leo's vids for example, whatever you hear when the NULL test is done (when the signals have opposite phase) is what the profiling is missing. If the signals would be identical, a Null tests would rendered silence.

If the stuff you're hearing is a noticeable part of the frequency spectrum, then accuracy isn't as good and you're most likely going to be able to tell a difference.

If whatever you hear is just static etc then it means the profile is pretty spot on.
Just my 2c.

Thank you @2dor !

Because the residual of a null test only tells you if there is a difference, not if the difference is perceptually audible.

My point and question exactly put.

Does anyone suspect that software/firmware revisions will offer the possibility for improvement on null tests on units converting NAM files? I imagine each product will face some hardware limitations that will vary… but perhaps the conversion process can be tweaked toward a more lossless state? I am also intrigued about what difference a multi-layered approach would have upon null tests… if anything?
