It all seems so simple. How do you remove the effect of the player? I can make profound changes in the sound of my horn by adjusting my embouchure and air stream.All that is needed is someone with a microphone and a spectrum analyzer so we can see which, if any, frequencies are different in a sound made by one piece of equipment versus another.
If KB already did that and is interpreting results, just show the waveforms so we can see the data behind conclusions.
