Use Medieval CUE Splitter to partition a FLAC if the file has an associated CUE file. A CUE file contains time-coded information about the separations between the different songs in the FLAC file. Launch Medieval CUE Splitter, then open the CUE file that's in the same directory as the FLAC. Click "Split," select the directory into which you want CUE Splitter to save the split FLAC files and click "OK" to partition the FLAC.
Split a single FLAC into its component songs using the Foobar2000 music manager and player. When you load a FLAC file into Foobar2000, the program automatically reads its associated CUE file and allows you to play individual songs in the FLAC as if they were partitioned. If you want to actually split the FLAC into individual songs, highlight the songs in Foobar2000, right-click one of them and select "Convert." Choose "FLAC" as the "Output Format," click "Convert" and specify a directory for the split songs.
Partition a FLAC into songs using Audacity if you don't have a CUE file for the FLAC recording. Manually splitting a FLAC file is a time-consuming process. However, if you don't have a CUE file for the FLAC, it may be your only option. Load the FLAC into Audacity, then click inside the waveform at the end of the first song. Click "Edit," then "Split." Repeat the process for the rest of the songs in the FLAC. Double-click the first partitioned song, then choose "Export Selection" from the "File" menu. Select "FLAC" as the output file type and click "Save." Repeat the procedure for the rest of the songs.
