In virtù di canali di comunicazione aperti da tempo, vi riporto alcune dichiarazioni provenienti da due venditori di musica smaterializzata, pervenutemi in seguito ad un sondaggio che ho effettuato presso di loro.
ricevo da HDTRACKS:
"Gianni,
We absolutely do not allow any upsampled content on our site. All of our high res albums are produced either directly from the original masters, or from SACDs, in either case transferred through high quality DACs set at the proper resolution."
ricevo da High Definition Tape Transfer (HDTT):
"Hi Gianni,
First of all my transfers start as 24/192 resolution I don't up sample any of my files and as you can see there is no need too because of the resolution of the original transfer.
Don't get into the trap of analyzing all your files you've got to remember many masters and commercial releases were manipulated with EQ and other devices at the time of their original releases
A good example of this is Dolby masters which many companies used in the late 60's up to the early 80's. Decca was a big proponent of using Dolby on there masters . (and by the way had some of the best sound of that era)
If you analyze any Dolby encoded release it has a chopped off HF region somewhere around 12k this is just the nature of the beast.
Also remember HDTT is more a archival service so we try to use the best source available, also 4 track tapes do have a compromised HF region per se which in my opinion doesn't hamper them sonically but you would have to be the judge of that."
