Low latency ?

Postby Dicko » Wed Jan 29, 2020 2:25 pm

I'm thinking of replacing my M- Audio 2496 soundcard . (latency about 6 msec).
Which type of device is there to go for that has the powest latency ?
There seems to be soundcards, firewaire, thunderbolt, usb and there maybe others.
Some even advertise "0 latency" which basic physics tells us is impossible.
So can anyone help as for which i should be looking at for a pc ?

About latency, have a look at my post in the forum here (and the other replies as well of course, which suggest specific bits of kit).

Hi Dicko,
I have for several years been an advocate for the Native Instruments KA6 especially when folks ask for low latency. I have used the 2496, still got one and the KA6 beats it as it will run at 32 samples. The old card only goes down to 64 samples IIRC ?

The KA6 has better connectivity than the M-A. Two very clean mic/line/instru inputs plus two more balanced line ins, S/PDIF and MIDI. All for less than £200.

When it came out there was nothing to touch the KA6 for low latency at anything close to the price. Things are rather better now but Pete K can probably advise on that.

Of course! IF the bank will stand it you could just get anything from RME and you would be set for at least the next decade!

Oh! And the KA6 has a better noise floor by some 6dB but that is academic really.

Dave.

Well true... we will always be limited by the finite speed of electronics in conductors at normal room temperatures...

The 'zero latency' term normally refers to the use of an analogue monitoring mixer built into the interface, so that there is effectively zero latency when monitoring the source you're recording through the interface. It avoids having to listen to a foldback signal from the DAW, which would involve digital converter delays as well as interface buffer latency.

Is Firewire or Thunderbolt faster ?
Everyone seems to be using usb,

How about a cheap presonus audiobox ?

Firewire is pretty much obsolete but used to have a bigger 'throughput' than USB but the likes of RME changed that and now other AI makers have generally caught up.

Thunderbolt can be fastest of all but do remember, USB is 'universal' TB is rare outside macs and probably an overkill unless you want a vast channel count. Cables are pricey (rip off?) as well.

No doubt a 'proper' PC person will expand further.

The reason USB is so popular is because it is 'universal', as well as being cheap, convenient, and more than fast enough for the job unless you're'wanting to run hundreds of tracks in and out of the computer all at the same time.

Latency is only truly a problem if you are monitoring through your DAW, or using virtual instruments. Otherwise it's a non-issue. Yet over and over I see people monitoring through their DAW and suffering latency that is completely unnecessary!

Most AIs have mixer panels and most will enable you to monitor incoming audio with zero, or near-zero latency.

Thank Guys
I do use virtual instruments and use a M-Audio Axiom 25 and a roland GI-10.
The hard bit is buying something you'd think reasonable and then finding that Cubase is telling you it has a terrible latency

My son found that driving Cubase (Ess 6) with a dumb keyboard using an M-A 2496 soundcard gave him easily low enough latency and that was with a very modest desktop, 3G Pentium single core and 1G ram!

I think the rot set in with the first flurry of external AIs? The early USB AIs were pretty terrible and have only fairly recently become much better.

You are in UK? I suggest you get as much info on your chosen AI as you can, ask VERY prenetrating questions of the vendor and if they are not forthcoming with the right answers, move on. Then, get your system in trim, clean and lean and when the AI arrives immediately put it through its paces. If it does not perform as promised take advantage of the Distance Trading Regulations..What they are for!

I'm in the UK .
Another thing i've noticed are people selling old versions of what i'm thinking are meant to be up to date stuff, (That's why it's cheap)
I'll have a hunt round, it does seem a minefield though. :headbang:

I also use very humble AIs when playing live, for instance (ancient) MBox2, NI KA6 and Behringer XR18 - none of these give me any problematical latency for live playing - so latency really shouldn't be a problem with anything relatively new.

Double and triple check that you are using an ASIO driver (not ASIO4ALL!), and that you have the lowest reliable buffer settings.

The 'mine' might come up with some Gold though! If you can find a Mk1 NI KA6 for around a ton you will have a super low latency bargain.
