I'm curious what latency figures you all are working with. I know this is subject to a whole gamut a variables, but what figure have you settled with.

I'm shooting Live through a dual 1.8 G5 with a Live buffer size of 512 samples at 48,0000 hz sample rate and I'm at 22 ms. My bottleneck, I believe, is an M-Audio Delta-44 PCI card.

Thanks!

well i can't measure my "actual" latency
but Live tells me that with the ASIO4ALLv2 driver i'm easily able to get 5ms @ 48khz. Buffer is @ 256 samples

EDIT: this is Stock HP Soundmax hardware.

Damn! That's sweet!

Why 48K?

Anyway, I also use 256 samples and get a 5ms latency (at 44,1khz), with an Audiophile 2496 PCI card on an Athlon XP 3200+. Would think your card should be better.

I can't hear or notice any latency when triggering stuff. But ofcourse when triggering stuff on external kit and then recording that into live as audio, I get a tiny bit of latency that needs to be corrected.

Right. I lowered the buffer to 256 and I'm at 10 ms. I'll run that for a while--see how things go.

Thanks!

4ms but that costs too much cpu
so I use 10ms

on a 1212M, 1G 400Ram, P4 3.2

1ms in 1ms out...
128 buffer @ 96k
digi002 rack
athlon64 3000+

system runs without a hiccup... with TONS of cpu head room...

1ms in 1ms out...?

is that really necessary?

AdamJay is referrring to either input *or* output buffer when he says 5ms. 256 would give you 10ms if you're counting total buffer time (5ms in + 5ms out). The manufacturer soundcard you use doesn't dertmine the latency, only how much CPU is used to achieve that latency.

If you're routing outboard gear through the computer (software monitoring) to use Live's effects in real time then you should run 256 or 128 otherwise your delay is too noticable.

I use an outboard digital mixer for all my outboard gear and my reference monitors are connected to that. The digital mixer is also equipped with a Firewire audio interface. This way I can play outboard, software, and record to the computer with 0 latency monitoring yet still use effects like EQ, compression, reverb, delay, and so on.

3ms and lower with my hammerfall pci card, and not even a slight change in cpu or a glitch . Rme are gods

Funny you should mention this. I notice in Live that the CPU meter barely changed whether I am using a 512 buffer or 64 buffer. Yet any other app I use the CPU meter changes. The trade off is that Live's CPU at 512 buffer is like Logic at 64 buffer. But if I change Live to 64 buffer there is almost no change in CPU. It's like there is something internally using CPU to support realitime audio. I also tested this on my PC with N-Track and have the same results using an Echo Indigo.

zero latency would be best.

Hello. I have a Edirol Ua20. I used to have no problems at all with it until I reinstalled windows. If I set the buffer to a usable setting, Live works fine but then playing mp3s (in winamp,etc.) is choppy as hell. I can't seem to get them both working smoothly at the same time like I used to. Are there any settings I'm missing. Here are my specs


Pent 4 2.8 with 512Ram (ddr)
Edirol Ua-20 (newest drivers)
Live 4.1
Thanks in advance.

PowerBook G4 1GHz, MOTU 828 MkII -> 3ms overall latency (1.5 in / 1.5 out) 48kHz, 24bit, 12 channels in, 14 channels out always active.
