Sorry for my silly question. It seems that EAC does not fully support FLAC files. Which is better to use with EAC? Is FLAC have better compression ratio than APE? I often use EAC to backup my CD to APE file format, and EAC also support to add APE files to write back to CD. Now I want to try with FLAC but don't know where to start? (pls don't tell me to use EAC to rip CD to WAVE first, then use FLAC to compress WAVE to .FLAC) When I go to EAC compression option, I don't see any thing related to FLAC in the "parameter passing scheme" drop down list. When writing CD(in the CD layout editor) EAC don't support to add .FLAC extension (only WAV, MP3, MPC, APE). Please advice, Thanks.
