Interesting thread. Especially about the recording aspect of it. My 2 cents is that while our playback gear and recording tech has advanced to a level where we can reproduce a decent percentage of the compressions and rarifactions that happened at the original event, it’s the mic technology that essentially hasn’t changed in decades and is holding back the entire pursuit.
In researching patents for a new (but very expensive) mic technology I’ve conceptualized, it seemed the more recent patents were mostly about lower cost ways to capture sound for phones, and for immersive 3D mapping, not the core tech behind capturing the nuances of those waves of air.
I’ve posted this before but luckily (at least before the pandemic) I had an opportunity to hear live acoustic music in home settings and small venues very often, and I’ve developed my ear to use that as a reference (often with my eyes closed), not other Hifi systems.
Just a few days ago I got to hear a trumpeter playing live outdoors here in NYC and stayed for a while just noticing what acoustical properties I was hearing, and how much inner detail there was, which is often not present in even top reproduction systems.
On a fun note, I have been hearing some battery powered portable music systems people walk around with here in the city and have at times been shocked at the level of quality voice reproduction they are able to deliver. Of course the realism is in a very limited bandwidth, but my point is that even the completely uninitiated are now hearing good quality vocal reproduction, with a lack of power line distortion (due to batteries) and without room interactions (being outdoors).
Real vs Processed
".....it's the mic technology that essentially hasn't changed in decades and is holding back ......."
Speaker technologies, amplifier technologies, etc. have NOT changed much either. Have you ever listened to a mic-feed of a properly set-up recording session? Even on relatively inexpensive speakers, the sound is direct, vivid, unimpeded and "real" BUT not REAL enough!
In my view ( with some experience in recording ), the predominant reason is our unrealistic, even incongruous expectation that the PROCESSED should be an exact facsimile of the REAL! Do we forget that microphones, amplifiers, speakers, cartridges, tapes, turntables, DACs ...our ears \ brains even, are processors!!! It is almost hubris to have such an expectation. We should be more than grateful that we have been bestowed with an infinite variety of components and, based on our personal aptitude, knowledge \ experience and taste, we can attain a level of sound reproduction that can momentarily suspend disbelief and consistently give us invaluable pleasure, satisfaction and, dare I say, the highest form of healing therapy!
The other reason for the "hold - back" is the actual STORAGE medium, whether tape, vinyl or hard disc ( hence my direct feed reference above ). The compression, veiling and obvious deviation \ distortion of the real thing is undeniable.The mics are not the weakest link, it seems.
This new mic technology that you have conceptualised ( and I really hope it is an improvement on current technologies ) will be just another "processor"; it can never "personify" the trumpeter in NYC, no matter how much more "inner detail" the mics capture, for it is NOT the inner detail BUT the real entity of the trumpeter that is missing!! And that is how it should be.
We should be aware of our limitations and delusions as designers, makers and listeners and celebrate and exalt the plethora of music and music-making equipment that we have at our disposal, for there is no greater path to edification than music.
I hope that I did not come across as too "aphoristic" with my genuinely felt comments. Good luck with your patents.
Cheers, Kostas.
