Missing Metrics - Latency!

[Dan Lavry]

Well, that should put to rest any notions of converter latency being too small to be consequential. It absolutely can be consequential for real time systems.

Have you made, or do you know of other converters with higher latency than that?

I appreciate that people like yourself are willing to provide this information for the high end products you make. It would be awesome if people starting out, with limited budgets, were able to make more informed decisions purchasing more affordable products. I think that is a great value that Audio Science Review can provide, this kind of information that manufacturers either haven't bothered to provide, or choose not to.

Of course, I still dream of a world where the work done by Amir and others wouldn't be necessary. Where I could pick up the box any audio interface came in, and read off the headphone output impedance. Where I could just read the specs for any ADAT converter rack, to know the ADC and DAC latency.

I don’t follow other manufacturer’s products. I know that the older Lavry Gold AD’s were great for some applications and un suited for others. The new Savitr AD is used also for mixing, overdubbing, tracking.

So latency is very important sometimes, not at all important other times.

Most analog electronics has very low latency. Most of the latency is due to AD and DA converters and all the digital stuff between (computers, DAW or any digital processing).

But it is also good to make sure that low latency (hardware or software) does not sacrifice phase linearity.

The Savitr, for example, latency of 103uS (0.103mSec) for 96KH at “low latency mode” makes the AD contribution virtually negligible. It helps compensate for other causes of latency. Normal mode is 249uS, still very low latency.

Clearly it is not just about latency, but the low latency Savitr AD expended our market significantly. Low latency is one of the reasons.
