Hi all,

A few months ago I made a FLAC decoder testbench: a set of FLAC files
specifically designed to test certain aspects of the decoding process,
including rice partition escape codes, non-standard blocksizes, a
variable blocksize, very small and very large predictor coefficient
precision, wasted bits and extremely large metadata blocks.

Currently, it is a zip file with 59 FLAC files and a README. All FLAC
files contain audio that is licensed under some Creative Commons
license. More information can be found here:
https://wiki.hydrogenaud.io/index.php?title=FLAC_decoder_testbench

Would such a testbench be of any use to this working group?

Kind regards,
