I see a people talking about imaging and sound stage but is there a way to these capabilities of an audio setup without actually testing them? Maybe something similar to a frequency response graph?
I am bot that knowledgeable about audio but isnt imaging/sound stage a function of audio resolution? As in the lowest frequency difference required to produce 2 signals without overlap? Can a measurement of peak width for outputs at single frequencies be an indication of resolving power?
Very simple. If the phase and frequency response of both channels are nearly identical, the system will image well. That’s the fundamental of “stereo”.
