FLAC decoder testbench

2025-10-01T08:12:17Z

Kode54: Updated Cog

To further the use and development of [[Free Lossless Audio Codec|FLAC]], a testbench containing files with different parameters was constructed. The testbench consists of 64 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.

The testbench can be [https://drive.google.com/file/d/1ECjkAyqV56xd9IZV-6zccG1Y-iE_hDMj/view?usp=sharing downloaded here (revision 7)] and [https://github.com/ietf-wg-cellar/flac-test-files is maintained here]. It is licensed under [https://creativecommons.org/publicdomain/zero/1.0/ CC0 1.0].

Revision 6 adds four new files (60 to 63); files 1 through 59 are the same as in revision 5. For more information on which file tests what characteristics and features, please refer to the [https://github.com/ietf-wg-cellar/flac-test-files/blob/main/subset/README.txt readme.txt file]. Revision 7 replaces file 63 (which was faulty in revision 6) and adds file 64.

FLAC decoder testbench

2022-05-19T00:03:48Z

Kode54: Updated Cog against latest test bench revision 6

To further the use and development of [[Free Lossless Audio Codec|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 [https://creativecommons.org/publicdomain/zero/1.0/ CC0 1.0].

The testbench can be [https://drive.google.com/file/d/1mQ1UV-hBQERD6dqcQRFtpMme9-gCvhod/view?usp=sharing downloaded here (revision 6)] and [https://github.com/ietf-wg-cellar/flac-test-files is maintained here].

FLAC decoder testbench

2022-01-14T07:19:36Z

Kode54: Cog: Update 8 channel test information based on app version history

To further the use and development of [[Free Lossless Audio Codec|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 [https://creativecommons.org/publicdomain/zero/1.0/ CC0 1.0].

The testbench can be [https://drive.google.com/uc?id=1ahwxfe3V78X4Dai1i844tzkZ-3chSmeS downloaded here]

FLAC decoder testbench

2021-12-11T11:06:54Z

Kode54: Added a notice for Cog for test 43

To further the use and development of [[Free Lossless Audio Codec|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 [https://creativecommons.org/publicdomain/zero/1.0/ CC0 1.0].

FLAC decoder testbench

2021-12-11T11:03:34Z

Kode54: Added Cog v1630

To further the use and development of [[Free Lossless Audio Codec|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 [https://creativecommons.org/publicdomain/zero/1.0/ CC0 1.0].
