Hi Ted, concerning the latency in Audacity. There is a setting for a latency correction in audacity. In the preferences dialog, in the recording category, there's a latency correction edit box. The default value of the correction is -130ms, and the more negative the value, the larger the correction. There are a couple of ways of adjusting this value so that tracks line up correctly. 1. The first is just to use trial and error. You don't need to get it more accurate than about 10ms. 2. The second is to use a method such as the one described in a guide to audacity for jaws users, which is available at: http://goo.gl/Qi2CeD In the recording section of this guide, there's a sub section on latency correction.
In addition to these two methods, I'm aware that someone is working on a plug-in to partly automate the measurement of the latency, but I'm not sure when this will be available, David. original message: Personally, I could not get tracks to sync up together so that they sounded correctly like they would in sonar or reaper. If someone could tell me how to make tracks line up the way they are supposed to, I would give it a try again. For example, while recording vocals, my second harmony part would not stay with the first, and I did not know how to make it line up. That is my two cents worth.
