Hi,
(sorry, my english isn't very good...) i have been working (for fun) on lossless audio compression since about 1997. Finally i would like to bring this thing (especially the never-ending-search for just a tenth of a percent more compression...) to an end. In the light of the big bunch of existing Compressors, i am not quite sure, if it would be of any use to add one more Compressor to the public. The preparations for a useful release would be much further work, and i wouldn't like to waste my time for something not needed. My Compressor uses similar techniques like FLAC, but far more elaborated. Compression ratios lie between Monkey's Audios High- and Extra-High-Mode (Can be better than Extra High at the expense of a considerable increase of encoding time). Encoding Speed is a bit slower than Monkey's, Decoding Speed is much higher on most Files. Seek-Times should also be better cause of the maximum (independent) frame length of 250 ms. I would like to read some opinions. Would it make any sense to release it? Thanks Thomas |

I've worked on something similiar the last years.
my encoder uses an adaptive wavelet filterbank on the prediction residuals.  it has id3v1 and apev2 support but i stopped developing because i think nobody needs yet another lossless compressor. best regards |
