Hello. I just finished writing and documenting a new lossless and lossy audio codec called
j2kaudio. It uses the wavelet compression in JPEG 2000 to transcode audio wav data to and from j2a
files. I have not written any sort of media player plugin yet; more testing and file format
refinement are necessary first.
I tested with 44100Hz, 16-bit, stereo CD-quality wav files, but it also supports other sample
rates, precisions, and channel numbers.
I tested against flac, lpac, shorten, and monkey's audio for lossless encoding. j2kaudio beat the
nearest competition by over 10%.
If anyone is motivated to test some additional songs, provide me with additional test data, or
suggest another untested codec, please let me know.

Let me know what you think. Thanks. -Greg
