Kind 4.1.1 & XP Users - Can you re-create this problem?
Posted: Fri Mar 25, 2005 11:13 am
Wondering if a few friendly Live 4.1.1/XP users can help me troubleshoot a problem I'm having with latency. I have this problem on both my Dell P4 512 laptop, and my AMD 2800 512 desktop machines. I'm using 4.1.1 (Lite) with an M-Audio MobilePre USB.
A mixture of MobilePre and non-MobilePre users would be perfect to isolate the offender, but I'll take whatever I can get!
Basically my problem is: my latency is NOT stable. It seems to change. If you have time, can you try this and post your results for me?
As per the "Overall Latency" guidelines in the manual, connect a cable from an output of your device (say, input 1) to an input of your device (say, output 2). As per the manual, continue as follows.....
In Live, have two audio tracks. Have the input of Track 1 as Input 1. Mute track 2. Turn monitoring on both tracks off.
In track 1, drag in a sample (I just use the default electronic snare out of the folders on the left). Click on the sample and make a not of where in the timeline the sound starts (mine starts about 10ms).
Arm Track 2 and record for a little bit. you'll see the recorded version of your sample appear in track 2. you may have to fiddle with the levels if it's clipped out or too quiet. Now click on the sample and see how much this sample is delayed by (if your system is setup perfectly and you have a figure entered for Overall Latency in the Audio prefs, there should'nt be any delay at all). Even if yours is perfect, bare with me!!
Now delete your new recorded sample and re-record, and do that about five times...
Is the delay of the recording in Track 2 CHANGING or STAYING THE SAME? (mine wanders about by between 10 and 70ms at a time)
Save your set, close live, re-open live. Re-record your sample. 3 or 4 times, deleting your recorded sample each time.
HAS THE DELAY CHANGED OR STAYED THE SAME? (mine is usually heavily delayed by at least 70ms, sometimes with some crackling noises PRECEEDING the actual recording)
If you have the time to do this test i would greatly appreciate it!!
