I have a single large FLAC file, have lost the CUE file, the recording is one from a friend's performance [not a commercial], so all I have is the track listing of song title and where it starts/stops on the time continuum.
Medieval's Cue splitter program works great.
I use Adobe Audition 3 and cut large files all the time into multiple files. When these files are burned onto a CD it plays through the 'cuts' and all you see is the track number change. There is NO change to the audio, no samples added or deleted. Consequently it does not have to be 'silent' where you perform the 'cut'. Once you get used to it (it's easy) you can separate 15-20 tracks out of a 70 minute file is a few minutes. Typing the files names takes the most time and setting the cut points is a snap. This can probably be done in Audacity as fast. Personally I prefer the program to have a 1/2 second 'pad' at the track change. Some CD players 'mute when selecting tracks and the half second gets past that without an annoying delay.G²
