SACD is not that a bad example of so called hirez 24/96 is PCM is much better ? (this is a very dead topic sorry )
SACD is equivalent of 20 bit in the bass and midrange and then the noise starts to rise and it is sligthly worse than CD at 20kHZ (not much) after that we have a lot of ultrasonic noise ? It's mostly SONY hype, and designed really really obscure to prevent copying in large scale. Many SACD players converts to 24/88.2 something internally before dacs, you can get machines with modded digital outputs even 6ch spdif. I dont have the numbers in my head right now but is not so that the very high sample frequency of DSD a large multiple of 88.2 or 96kHz ? so this 1 bit high frequence signal can get mathematically convertet to a suitable PCM format and back without any loss of information/fidelity. It's often done due to lack of DSD software for mixing and then made DSD again before mastering. But you can get good 24/96 material from itrax for example, this is real 24 bit recordings. The big deal with DVD-A and SACD was multichannel, rigthly done this makes more for the music than any sample rate imho. But to repeat myself recording with 24/192 to avoid filters and have a hirez signal for further processing makes sense. But 24/96 is a perfect delivery format for consumers it never needs to be better! I read somewhere that around 20bit 55kHz would be sufficient for human hearing in the best case scenario. But then there is no slush margin for human errors somewhere else in the process, like some really old CD's where the producer had so much headroom so you never saw 16bit anywhere. -- Mnyb -------------------------------------------------------------------- Main hifi: SB3 (soon to replaced by a Touch :) It is on preorder) Bedroom/Office: Boom Kitchen: Receiver (soon to be replaced by my SB3 and the SBR to be stuffed in a box in the attic ) I use a Controller various ir-remotes and a Eee-PC with squeezeplay to control this ------------------------------------------------------------------------ Mnyb's Profile: http://forums.slimdevices.com/member.php?userid=4143 View this thread: http://forums.slimdevices.com/showthread.php?t=74688 _______________________________________________ Touch mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/touch
