Live's Utility audio effect can convert a hard-panned audio file (playing out of one speaker only) to a center-panned one (playing out of both speakers).
In order to burn a Live Set to CD, you need a program capable of burning CDs, such as Nero (PC) or iTunes (Mac).
With sets made prior to Ableton Live 8.2, you'll need to select the “Fade” mode on Simple Delay, Ping-Pong Delay and Filter Delay by right-clicking on the header of the effect.
A: When recording audio for a long time, Live suddenly stops recording and eventually crashes. B: The message “Live only supports rendering files of less than 2047 MB” shows up.
