Returning to the initial question, I still have not found a way to split a large flac/ape file into mp3 tracks, and writing relevant id3 tags into resulting tracks, in accordance with the information in the cue file. I'm still trying to brew a stew from sysutils/bchunk, multimedia/ffmpeg, audio/flac, audio/id3tool, audio/lame, audio/mac, audio/mp3splt, audio/shntool with rather little success. -- Victor Sudakov, VAS4-RIPE, VAS47-RIPN AS43859
