[QUOTE=space2012;4375315]Thats called Aperture error.
higher sample rates need smaller clock pulses per second.
higher sample rate needs smaller jitter, becouse same jitter affects more the smaller clock pulses.
Analog-to-digital converter - Wikipedia, the free encyclopedia
problem with x2 x4 sample rates its the DAC, some consumer level DACs sound much better at x2 x4 sample rates,
... recording at x2 or x4 sample rates needs a more accurate clock, but thats not a problem with Atomic Clocks like Teac Esoteric or Antelope 10M.
processing at double or quad sample rates also needs more DSP/CPU.
but the DSP is not a problem these days with new i7, Xite-1, FX Max Teleport, etc...
another problem is processing at 2x or 4x, some plugins are not well designed, and frequency range changes drastically when used at 2x or 4x.

that makes sense but may actual question is: are clocks more accurate at higher sampling rates? OR - do stay the 'same' having the same size errors (in time) which would have a greater impact on a faster rate sample. OR - do they actually generate even larger errors.
OR??
as i understand it jitter is more of an issue when sync'ing units. I only go in the box once and out once.
I have moved up from an Maudio 1010 (using at 24/96) to a Motu hd192 (using at 24/192) ...the difference in the ability to mix the low end is VAST.. and the top end is more open.
I do not have means to do a measured A/B test at different sample rates on the Motu..does anyone have any real data out there concerning jitter on this unit?
I was going to get the Black Lion audio mod and the external clock ..after reading this and other threads here I have scrubbed the idea of the clock since I am not actually syncing any other units to this.
eh??
