Latency / I/O buffer size control

[JLow]

is this the only place to control the Latency when tracking audio?

 

still notice a little bit of annoying delay even set @ 64....not killing me but i could do without it ya know.

 

Process Buffer Range:

Small, Medium or Large....which prevents delay if at all?

 

does it help to download any Presonus software or something like that.

is DAE or Direct TDM perform better?

 

 

no big deal really i am just sick of hearing people i track bitch about it.

 

thank you in advance. i think i am the dumbest person in this forum. you guys are all so well informed.

 

 

loving you,

i/o safety and buffer range both add latency. To get the lowest latency, you would want to uncheck and set to small, along with 64.

 

Also, the plugins that you have running will add latency. For instance, change the lookahead of your limiters to 0 so Logic does not have to compensate for lookahead by increasing latency.

When tracking, uses the Low Latency Mode button on your transport.

It works great for temporary work.

Sure - the 64 samples setting normally means circa 3 ms latency in addition to the latency added by the converters, the I/O buffer Safety Buffer (turn it off!) and FireWire (if you use a FireWire interface).

Large means more latency.

DAE/DTDM can be used only if you have a TDM based Pro Tools system.

If people bitch about it, it is IMO a big deal.

 

The solution is to turn off Software Monitoring and to set up your (soft/hard) mixer to monitor directly.

No, the dumbest part of this problem is that the manual doesn't describe how to get lo latency or what extra latency we should expect by using Software Monitoring, larger Process Buffer Range and so on.

 

The Low Latency Setting won't make any change unless you have plug-ins in your recording (monitoring) path that adds latency.

thank you all so much.

Also, it's very important to be aware of the plug-ins that cause the most latency... and how you can still use software monitoring but lower your latency.

 

Biggest latency causer: Limiters... since they "look ahead" you have to wait to hear the output. The default setting for Logic's adaptive limiter is 50ms. You can set it higher too causing more latency. This means that a very acceptable (by most people's even highest standards) 3ms of latency caused by your audio preference settings is only a small fraction of the real latency which would be at least 3ms + 50ms = 53ms. You can decide to not use the adaptive limiter at all until you're done tracking, or use a different limiter while tracking. Logic's normal limiter is set to a 2ms look ahead by default (and you can turn it down below 1ms). This is more reasonable and should allow you to track without complaints. If you have an adaptive limiter anywhere in your project, then even though it's not on the track your recording, it'll cause the whole system to have latency.

 

Compressors and Reverbs also can cause latency... I often use simpler plugs while tracking/composing, then add the better ones when I start mixing.

Logic's plugins seem to cause much less latency than third party mastering plugins, so I don't use any until I'm ready to bounce.
