"Problem sample" question.. 2003-03-29 01:52:05 This has been something on my mind for awhile.. I just want everyone's opinion on this:A good friend of mine builds amplifiers in his spare time, and is a genius at it. He used to work for Cary Audio Design(world-class tube amps, etc). His way of tuning an amplifier with different components is all by ear. Me and my brother help him out sometimes when he brings new projects over. We've never done a blind test or anything like that, but can undoubtly tell when something sounds better than something else. For example, we recently swapped in some better audio-grade caps in my brother's amplifier(over the "5000 in a roll" type caps ), and the sound was distinguishingly less harsh than before. That was unmistakable, and there were no "samples" to be had, it was the overall sound that was different.So my question is, are codecs ever tuned by the overall sound of them? Some differences I hear aren't in a specific sample, or maybe undetectable in a specific sample, but range over the whole piece of audio. As in, "Yeah, that sounds less harsh overall." Instead of "That specific hi-hat sounds less "tizzy."" When I switched to MPC over from MP3, I WANTED my mp3s to sound better so I wouldn't have to go back and re-rip/encode all my CDs again. Much to my surprise, MPC sounded distinguishingly better, though I couldn't come up with a small sample of music to prove this. Perhaps I could do it with a minute or two of music, but nothing as small as 10 seconds.Anyone get my mean?
