comparison
The purpose of the comparison page is not only to show how compression ratios and encoding/decoding times using the flac reference encoder compare to other lossless encoders, but also to compare features (for example, some coders archive only and files must be uncompressed completely before playback can start). Keep a few things in mind: I make an effort to keep this information as accurate as possible, but if any of the data is wrong, let me know and I'll correct it. For another comparison (with graphs) of lossless codecs, see here.

Note: the comparison tables are getting a little stale for some of the other encoders; for some alternate comparisons and other lossless information see these links:

Reviewed encoders (besides flac of course): If you take maximum compression ratio and speed out of the picture (as you will see later, most coders exhibit similar performance), here is a subjective sort based on overall "usefulness". As far as features go, having source code gives you the most freedom since you can add anything you need that is missing; besides, open source projects tend to get better faster than closed source ones. A close second (depending on the user) would be OS support or plugin support.

The machine I used for encoding the test files is a PII-333 with 256 megs of RAM, running Windows NT 4.0 SP5. Unfortunately, Windows is the lowest-common-denominator platform for all the encoders. Apple Lossless was tested on a newer machine (P4-2.4GHz Windows 2000); only the overall encoding and decoding times are shown, and the times are scaled to the PII-333 by multiplying by the ratio of flac times on the PII to P4.

The input corpus currently consists entirely of CD music tracks. In the future it may include more kinds of input (like speech, other sample rates/resolutions, etc). There are 14 tracks whose genres range from rock to pop to death metal to classical to chant.

The first table is a summary of results on all input tracks. The remaining tables show the results of the encoders on each track. The summary table has more modes, whereas the individual tables have just the interesting ones.

In the summary table, entries are sorted by average compression ratio, which is the average of the ratios for each track; this keeps long tracks from having more influence than short ones. In the individual tables, this is the same as the straight compression ratio, which is compressed size / uncompressed size.

Some interesting things to note: This is a summary table with just the most 'economic' modes (the ones that give the most compression for the least amount of encode/decode time) for each codec.
