The purpose of the comparison page is not only to show how compression ratios and encoding 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:

  • As far as I know, only three of the lossless encoders out there (Bonk, flac and Kexis) are truly free (source code for Shorten is available but the license is more restrictive). Most others give out free binaries, but without access to the source, you are leaving your data to the whim of the maintainer for eternity; you have no way to port the program to another OS or fix it if it breaks. This can be a serious drawback unless the format has world-class clout (like MP3).
  • The compression ratios and times are representative only of the reference encoder. They are not indicative of the limits of all FLAC encoders or the FLAC format itself since the format is open and extensible, and anyone is free to write a better FLAC encoder. And it is almost certain that the reference encoder itself will improve.
  • Since FLAC supports streaming, it is at a slight disadvantage to the formats that don't because they don't have the extra overhead of all those frame headers.

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.

Reviewed encoders:

  • flac of course.
  • Bonk - An open-source source codec. No player or library support yet.
  • FROG - A closed source, Windows-only codec, with a Winamp plugin.
  • Kexis - An open-source source codec. Still in the alpha stage. No player or library support yet.
  • LPAC - A closed source codec. At least it's available for more than just Windows, but there's only a Winamp plugin.
  • Monkey's Audio - A closed source, Windows-only codec, with a Winamp plugin.
  • Ogg Squish - An open source source codec that is no longer maintained. The version I tested, 0.98, was the latest I could find. I don't have Windows timing results but it is among the 'fast' coders, based on UNIX tests.
  • Pegasus-SPS - A closed source, Windows-only codec.
  • RKAU - A closed source, Windows-only codec.
  • Shorten - A.J. Robinson's well-known codec; source is available here.
  • WaveZIP - A closed source, Windows-only archiver. Uses the MUSICompress[tm] engine which supposedly has a patent. I used to have a link to the company that makes WaveZIP (GadgetLabs) but apparently they have gone out of business (maybe for trying to sell something that should cost nothing).
  • WavPack - A closed source, Windows-only archiver.

Encoders I couldn't get a copy of:

  • AudioPak
  • WavARC

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.

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 death metal to pop to classical to chant.

In all tables, the results are sorted by compression ratio, which is compressed size / uncompressed size. The first table is a summary of results on all input tracks. The remaining table shows the results of the encoders on each track.

Some interesting things to note: LPAC quality settings are not too stable with -r (which allows seeking during playback) turned on. In all but one of the files I tested, the 'normal' mode made the smallest file, and much faster, so I have included only 'normal' results. RKAU also has a tendency to get bigger in the 'high' mode. Shorten's method for quantizing the LPC coefficients is not very good which is the main reason why the fixed predictor runs are both smaller and faster.

Another ironic fact is that the encoders that are patented or cost money turn out to be the worst by most measures. SPS is so archane and crippled that I gave up trying to put together results for it after one track.
