@yoyoyaya Just curious: some of the best CD I heard were very simple (almost?), 'direct to digital' with a minimum or no mixing, mastering, etc. Ideally a few mics, volume mix, A to D conversion and 'burnt' onto disc. In this context, I remember one guy who experimented with digital tape recorder early on (40 years ago). One recording he played was in the middle of the night (low background noise level) recording a tripping faucet in a small bathroom, and then someone opening the door quickly. Played back from the digital recorder over a stereo with a 'bed' size sub (built like a queen size bed), the dripping was eerie, but when the door opened, the pressure increase in the small bathroom was noticeably reproduced by the sub.
SO, are there some (obscure), maybe 'audio test' CD for SACD that make use of very little 'mix mash'?
