I'm going to grab some audio from DVD in best possible quality. My software supports FLAC encoder and lets me to choose various bit per sample settings for it: 8, 16 or 24. And I got confused.
FLAC is a lossless format. So the results of encoding with --bps=8 and --bps=24 should be the same quality. My software indicates that expected filesize with --bps=8 will be much smaller. So why it lets user to choose this setting? The smaller filesize with same audio quality is always better! Is the deal in speed of encoding?
After some googling I found a few mentions about different audio hardware that supports bps < 16 and doesn't support bps 24 etc. So it might be not about encoding but about decoding - if you encode in bps=24 you may face with some problems with oldest hardware while playing. And with bps=8 newest hardware might not provide best quality...
So, I'm confused. What is a real meaning of --bps for FLAC? Or at least: Should I choose --bps=24 to save audio in max quality or --bps=8 is enough?
