Why are you making this so complicated? Software? No. Ears!
Seriously, converting sound energy into electrical energy is never transparent, and then converting it again is even worse. The physics is complex, but ALL guitar cabs are soooo different to monitor or hifi speakers. They are designed to mangle the sound in a musically pleasant way. Think of them like an effects unit. 8 x 10” in a huge bass cab, or 1 12” in a pretty poor acoustic designed cabinet. Then the speaker gets modified in the way it is wound or how stiff the cone is. The miking of a cab then changes it yet again. Mellow near the centre, harder near the edges. The variables are huge. So all you do experiment. In commercial studios, until you hear the guitar, the email you have with the details gives you no clue as to what the player wants. You guess, based on the last similar setup and player. They don’t like it.you try to convert words to a sound. “It’s not dishy enough?” What does that mean? If you have placed the 57 on the centre, move it away and repeat. If it gets better for the player, not you, but not perfect, swap the mic to one that will enhance the change. Software might make the changes easier to do as you dont have to keep physically moving stuff around, but it’s like constantly trying different tyres on your car when the real issue is the track rod ends are shot. Guitar and bass cabs sound absolutely terrible if you put music through them. Really low fi. Super quality mics do not do much, there’s no actually quality there to capture. You need a mic that compliments whatever horribleness the player prefers. That is why DI’ing is out for many people. They don’t want the sound that comes out of the instrument, they want the end sound, and that includes everything that changes the guitar sound.
