Convert LPCM to FLAC
LPCM audio is the inexpensive way of getting HD-audio onto Blu-ray. Instead of using a licensed compression format like TrueHD or DTS-HD MA the LPCM track is a raw uncompressed track. So the quality is great but it typically takes up a lot of space, because it's not compressed at all.
So it's fair enough that LPCM has the greatest compression ratio from 50% up to 80% for multichannel audio soundtracks. Such compression allows us to save around 10% to 20% of space for movie itself. In the same time 24-bit mono or stereo layouts will not have much impact on overall size.
