I will do my best to be as clear as possible, forgive me if things turn to rambling.....
Ok so since 2008 ive been using an 10,IN 10,OUT roland ederol audio interface, with a imac both with firewire, all cool works great no probs,ive used all inputs recording drums to logic...no latency no probs, best desition i made after years of pcs and installing sound cards that were rubbish...its been like heaven for me, just used for my private projects...used a small desk as a patchbay as im always plugging things in and out. silence from the speakers all good. For a few years ive been checking out desks with built in audio interfaces...but things have popped up where i might be in the market for one sooner than i expected. So here's my main point, i was looking at the allen&heath zedr16, but no longer available, neither is the mackie 1640i which was running second, both firewire so i thought i was ok. Now new on the market is the tascam model 24, but usb. Then i watched a youtube video, where they're still talking about latency with usb,and firewire will be discontinued on new mac models because of the expense? And now thunderbolt is the one to go for. Why change something that works fine? So guess my questions are
1. Does usb cause latencey?
2. Is a usb to firewire cable anygood? And if firewire is faster does it slow down when it gets to the usb connection!
3.do i need to worry about any of this? I thought latency was from the 90's?
The tascam is usb2 and i would need all available inputs from the interface recording simultaneously without latency...can anyone set me straight?
As far as I know, it's not about latency but bandwidth. Again, I'm no computer whiz but I think USB 2.0 has enough bandwidth for most audio applications. If you're recording 8 tracks at a time, you should be fine with almost anything.
Looking around google quickly, it looks like Thunderbolt is more closely linked with the PCIe bus on the motherboard so I guess you get even less latency with that. Then again, they say USB has lower latency than firewire. Really, if latency is that much of an issue for you then you can always get near-zero latency with direct hardware monitoring through many interfaces.
Seems to me that latency has more to do with how low you can set your buffer which is related to your CPU. You're always going to have some latency, it's just a matter of how much you can tolerate. Anything USB 2.0 or newer should be fine assuming your computer is newer than 10 years old and wasn't a basement bargain to begin with.
Ok cheers hexspa, that settled me a little,youtube seamed plagued with latency vids about usb,i was really confused why this would still be a issue in 2019. anyway thats cool, im sure i will look up one day from what im doing and the world will have ended!
