Hi, I want to ask about the latency of DACs. I recently bought a little DAC to use between my Xbox One (optical out) and my Cambridge Audio 840v2 amplifier, for playing Rocksmith (a guitar game). Unfortunately, I get a delay of something like a tenth of a second between playing a note on my guitar and the sound coming out of the speakers. I didn't get this noticeable delay with my Xbox 360, which has analogue audio outputs, and it's annoying that I get a worse delay with the more recent hardware.
I've looked through this thread and searched on the forum and I haven't seen much information on the latency of DACs. Elsewhere I've read that this should be negligible - perhaps around 2-5 ms, which isn't much in the context of the lag I'm experiencing of something like 100ms. However, I wonder whether some (particularly cheap) DACs might be much slower?
Of course, if you're listening to a CD then a delay of 1/10s is unimportant, but in my situation, where I'm playing the guitar and want to hear the amplified note without a noticeable delay, it's a different matter.
I'd be willing to buy a more expensive DAC if it solves my problem (within reason - this isn't high-end hifi, so I won't be spending hundreds of pounds), but I don't want to do that unless I'm pretty sure that's the problem.
The DAC that I bought was this one (on Amazon Germany) - there are loads of little DACs like that, and they all look much the same so I picked one more or less at random (obviously looking at reviews, features and price).
Any thoughts? |
