Guys .... get your facts ligned up and use them the right way please.
I see things like Pro Tools monitoring having 2 - 3 ms of latency versus other analog analog monitoring systems having no latency ? Care to explain that please ?
Simple fact : data in the computer needs to be translated to your monitors : the DA process .... That's 2 - 3 ms latency Tom is refering to with TDM systems but make no mistake : ANY DA convertor will give you that kind of latency.
Latency is a complex issue and can is way too often used and even more missused to argument one or the other.
In this particular case : tracking.
In tracking at some point you have to go through a AD stage to get into your computer. AD's all average round 2,5 - 3 ms @ 48k. That is the time the convertor needs to translate the analog signal to a digital signal. No way around that wether you use a native or a TDM system. Now , here is the important difference with a TDM and a native system .... what happens AFTER that initial AD latency.
It's the latency that's added at this point that becomes important ... especially since during tracking you have to go back out and listen to what you're doing ... monitoring.
Monitoring adds you're typical 2,5 - 3 ms of DA convertor latency to the signal. Similar to the AD stage..............
