This is a bit of a embarrassing question, but do you all think it is possible to train your hearing?
Hm. I think that to choose, you ought to pick whatever sounds most realistic. Obvious perhaps, but yeah.
I think, maybe, the hardest thing to get just right for most folks is the human voice, because of your extreme familiarity with it. Processed sound effects, and a lot of pop music in general, are not very familiar to us in the real world.
I find it similar to the video side of things. I can watch reference quality PQ with something like Ratatouille, even with inaccurate colors, but if human faces look a bit too reddish or greenish, I might notice much more quickly because of my extreme familiarity with what a human face looks like.
I know I'm not really answering the question, but pointing out something that might be of introductory importance to you.
It would be great if the was a reference CD and booklet that you could listen too and read to somehow calibrate your ears. This way you could learn what to listen for when you dont know what to listen for ,?,?
This is also somewhat of a loaded question. Classical musicians sometimes completely alter the way they might record something. The extraneous noises on a string, or the very briefest interruptions of legato, are much more forgivable, if even perceivable, when they're simply just trying hard to "belt it out" for a large audience. Maybe that's like the difference between how an actor performs on stage, as opposed to in front of a camera.
Then sometimes the recording techniques are so different. I know very, very little about this stuff, but have picked an expert's brain on this subject here.
HOWEVER, the above will result in a moot point for many audiophiles, for the speaker should just reproduce what is on the recording; with the assumption that the recording is sufficient in this regard.
Is it possible to do? Or do you need someone to teach you what to listen for?
I think, for starters, look for what seems to be very realistic vocal reproduction. Then go from there is what I might say . . . ?
