Delay when recording audio

I've got my Sonar 2.2 installed. I've got sound, but when I'm speaking in the mic to test, there is a delay from the time I speak until the time I hear it through the monitors. I've tried moving the buffer fader, but when I move it closer to fast, it's all snap, crackle and pop. I'm using the C-port/dsp2000 dac and sound card to record. I followed the set up instructions from the ST Audio website(for setting up the C-port with Sonar). I think I've got everything the way it's supposed to be. Any ideas or suggestions?

Disable Input Monitoring.

Options > Audio > Input Monitoring
 
I'm at work right now, but I'll try that when I get home.

Thanks man,
Bill
 
once this option is disabled, what functionality do you lose?

I have never truly understood the input monitoring functionality.
 
As it suggests, it allows you to listen to what you are recording whilst you record... ie monitoring your inputs... when you use this you will also hear any effects that you have on the channel.

What I prefer to do is to use the ASIO drivers and configue the ASIO control panel so you can monitor 'near' 0 latency, however without any software effects applied.

Hope this helps,

how do you get so low?
I can barely get to 35 msec---no matter what i do it does not go lower. what determines this number anyway?

how does the computer calculate what the latency is? and how can we change it?
 
kktk.... when I get a 'near' 0 latency it is because it is not running through the computer... it comes into the audio card and straight back out to the monitors which are plugged into it...

I should mention that when I use 'input monitoring' I'm down to 5.8ms but I reckon I can get down to 2-3ms.

What audio card are you using?

Porter
 
delta 1010.
how is your setup?
how and what do you record?
do you have a mixer in the picture too?

i would love to hear other better ways to do this.
 
I'm running an Edirol DA-2496 on a P4 1.7Ghz, 912Mb RAM, 7200 30GB Baracuda HDD (8ms seek time) and a crappy 10GB HDD, Sonar 2.2 XL & Windows XP Home Edition.

I record straight to my DA-2496, no mixer... as such.. using ASIO Control Panel (which the Delta has) I route all my inputs to the 'monitor mixer' which is basically 2X1/4" plugs which go staight into my monitors...

I record Vocals, Guitar, Piano, Bass Guitar (and Drum machine).

I checked you card and it does allow "zero latency hardware monitoring"... that probably the way that you want to go.. but as I said, monitoring that way you won't be able to hear any software effects on the track(s) you are recording.

That worked dachay2tnr, thanks. My latency is 5.8ms which is pretty good I think. I did some recording yesterday and everything is sounding good.

thanks,
Bill
 
5.8 ms latency shouldn't be that bad. Have you measured your efficient latency?

To compare I use Input Montoring with 2.9 ms and I don't have any problems, even when I'm programming drums. :)
 
How does one measure the efficient latency? I'm kind of new to the whole latency thing. I used to use Pro9 and had no idea about any of this stuff until I found this board!

and this has nothing to do with adjusting your buffers? if so how do you do it?

From what I understand, Nope. The buffers are only effect the interface between the computer and the sound card. In my ASIO control panel I have the ability to adjust the levels of all my inputs (which I leave at 0db). I can set my 1/2 Out to a monitor mix and that way the audio doesn't go from the sound card to the computer and back to the sound card.. the audio goes straight to the output jacks.

I've attached a pic below... the screen on the left is the monitor mixer and the one on the right is the Patchbay / Router... used together effectively '0 latency'.

So basically what you're talking about is Direct Monitoring. The input of the soundcard is directly routed to the output of the soundcard without going through the computer at all... right?
 
Oh... I see. Kktk asked what function you lost with
Input Monitoring, not Direct Monitoring, so I was a bit confused...


Kktk if you're still listening: If you disable Input Monitoring you will loose the ability to test realtime-effects on the armed track before recording.

Hey moskus,

Thanks for the info and the website. It looks like I've got alot of reading to do!
