Thanks so much Robert for your response and the pluggin. I'll install it and give it a go. What I'm trying to do is some multitrack recording of original music and other multitrack projects. For this I need the tracks synchronized as good as I can get them and that's why Latency is so important to me at this point. I'm sure I'll have more questions as I go along and really appreciate everyone's patience and suggestions. I'll post my projects if anyone wants for critique unless we're not supposed to do that. Take care.

Hi Steve,
Latency correction is firstly cumbersome and secondly not constant.
You will perceive that the correction does not hold true for each
session and recording.
Anyways, that's not the point.

I've written a plug-in to facilitate the whole procedure, I do attach
it (don't know if this works with mailing lists).
Put it in the plug-in folder and restart Audacity, it will appear in
the "Analyze" menu.

All you have to do is:
- Create a default (~120 bpm) click track (or the sample sound from
within the plug-in).
- Record at least 4 seconds.
- Select all (Ctrl-a)
- Call the plug-in -> Analyze, Accuracy about 5 or (better) higher -> OK.

If all goes well, The message box will tell you the exact value to
enter in the preference dialog.

It is important to select always two tracks in order to do the
analysis, otherwise only half of it is done (namely catching the
original sound).
The "Latency Info" can also be used to align similar tracks, e.g. to
insert good passages into bad ones.

Tell me if it works for you.
