Version v2.25 with D-Lev support is ready.
In general, the calculation is performed using the formula given above, only a part related to automatic calibration at a specified distance is extracted from the coefficient “K0.” This part is represented by a separate parameter ACAL, which can be set either manually or by pressing the “Set ACAL” button.
In private discussion with dewster, we came to the conclusion that the “D-Lev” mode slightly incorrectly models the musical scale in the near field of the antenna. This is due to the fact that in my model, the hand’s movement always has the palm facing flat against the antenna, while he approaches with the edge of the palm.
I think that if we conduct the corresponding measurements, the match will be more complete. Unfortunately (but to the joy of the performer!), there are a great many playing techniques (as well as hand shapes). In this regard, it is simply impossible to conduct such measurements for all cases.
