Now paying more attention than in years to the sound quality, I found that the 4K movie soundtracks sounded anywhere from good to excellent. So I trotted out some of my old Telarc, Arkiv and other 44 Khz pipe organ stuff. Didn't sound as good as I expected. Certain higher (maybe 2-4 KHz) register diapasons sound accentuated, and have me reaching for the treble control from listening fatigue. Next thing was, listening to Steve Colbert on Late Night (Dish), I noticed his voice has a harsh edge or rasp (no politics intended). Noticed a trace of this on some other voices/channels, but less obvious.
I need to know why those things, but not movie tracks, exhibit this distortion (to do with sampling?). I eliminated my hearing as a cause because other people hear the harshness also. I tried other speakers, listening very close to a speaker, and a different AVR and player; same results. I've read years ago that CD's can be harsh sounding compared to analog, and I know that networks can have sound problems, so am wondering if I should order some SACD's to evaluate further. Anyone have these problems? Suggestions welcome, including titles.
Please post a measurement of the monitoring at your listening position, if you can.
It's always possible that a mix/recording contains aliasing artifacts, but since we are talking about an organ recording, I don't believe that aliasing is the reason for any harshness.
China condenser mics also can sound a bit harsh, but that's more a problem of voice recording, less of instruments, especially organs.
Ofcourse I don't know if it is the case in your room, but what you describe sounds like a result of non-linear monitoring, since you don't experience it in movies.
The 2-4 k range is very important for treble. Too much of that range and it turns into harshness.
So if a music mix is a bit hot in that range (or if that range is simply a bit too dominating compared to the other frequencies), and the monitoring is emphasizing that range too, it can sound harsh, while mixes, like movies, that are not that hot in that range, can sound not bad at all.
If you don't have one yet, you need to get a measurement mic and use REW before making ANY further decisions.
