Lossless Compression Reply #25 – 2002-02-28 19:38:06 Guys guys guys... (gals?) ... all of 'em compress closely enough that size isn't much of an issue. If speed is the issue, then look at that. If cross-platform compatibility (whatever OS you use) is the issue, then look at that. Whatever is the main issue for you, if any!For purposes of trading between a wide variety of systems, FLAC makes the most sense... right now. Any or all of these encoders could go cross-platform in the future, if they get popular enough. Given, open source is a benefit too, but IMHO not critical for encoding/decoding purposes (if you like programming...)As for FLAC becoming the defacto standard, I wouldn't count on it. The "best" rarely gets to be the standard, in the real world -- other factors (like popularity & blind chance) determine success. So all of us might be doing some re-encoding a few years from now, cuz *the* format might not have been invented yet.
