Latency...?

[nms]

I have the M-Audio MobilePre Breakout Box and when i plug my guitar in, open garageband and test the garageband amp settings there is quite a bit of latency.

Ok, i lie, there is absolutely no latency......until i plug in headphones/hi-fi into the lineout on my Mac Mini, THEN the latency begins. There NEVER used to be any latency when i did this...

If anyone thinks they can help, has any more questions or has the same problem....please post! You know the drill!

When you are listening to the headphone out on the Mac, you are listening to the sound after it has been captured, buffered, effected, buffered and output. There will always be latency because you have a A/D and a D/A stage in there, not to mention the effects.

Your Mobile Pre has a zero latency hardware monitor option where it feeds you a headphone signal before it digitizes it. (Edit: This will be without effects, of course)

Using the Mobile Pre's D/A for monitoring GarageBand with effects may provide less latency than the Mac's headphone out (why did you switch to the Mac output, anyway?)

Edit-- Keep in mind that the more effects you add, the harder it will be for the machine to keep up, and you may have to increase the buffer size (and thus latency)

D/A? (sorry, i suck.)

and i switched to the mac output because i wanted to hear the amp settings. it never used to do that the first time i used it, nor the second....curious.

Digital/Analogue.

As in Analogue - Digital converter. You should be able to hear your amp settings through the MobilePre with minimal amount of Latency (probably around 11ms at 44.1kHz).

Otherwise set your amp sound, then record using the MobilePRe's zero latency option so you get your tracking right. Really though the latency from the Mobile PRe should be liveable.. I used to have one and I used it while playing keyboard and it didnt ever bug me.
