Revision as of 17:55, 17 May 2022

To further the use and development of FLAC, a testbench containing files with different parameters was constructed. The testbench consists of 59 FLAC files, each one having a different combination of characteristics (like samplerate, bitdepth and number of channels) and FLAC features (like blocksize, maximum partition order, maximum predictor order, maximum predictor precision etc.) However, all combinations fall within the so called subset: a limited set of FLAC parameters that fit in the frame header and are supposed to be 'streamable'. Please be aware that certain tested features (such as blocksize 16 or a samplerate of 38457Hz) are pretty much useless in day-to-day usage, and that failure to properly decode such a file is mostly of interest to developers than to users.

For more information on which file tests what characteristics and features, please refer to the readme.txt file that is included in the testbench. This testbench is licensed under CC0 1.0.

The testbench can be downloaded here (revision 6) and is maintained here.

Table legend
Plays all files in this category are played as intended, without glitches, changes etc.
Rejects One or more files are rejected by the player, either by skipping the file or mentioning a message like: "file not supported"
Fails One or more files are not played back as intended, for example by stuttering, garbling or playing at incorrect speed, or by never starting playing (though not skipping, freezing or rebooting)
Freezes On one or more files, the player crashes on decoding, leaving the unit inoperable until reboot, or the unit reboots by itself
The order of precedence is from bottom to top, so if one file freezes the player, one file is rejected and the other play fine, the table reads 'Freezes' for that category.
For the metadata tests, the (absence of) rendering of the metadata is not a criterium, simply whether its presence is an obstacle to playing
