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 |

TBeck, could you describe your basic algorithm ideas in short? Will you publish a paper?

I have been working on this since about 1997, but never even talked about it. Ok, if my friends wanted to invite me for some beer, i told seem, that i couldn't go with them, because i was near to a breakthrough in audio compression technology (This never really happens...). My decision to go into public was a spontaneous one, in no way prepared. So actually there is no paper. My improvements are mostly the sum of many single optimizations. One of them may be remarkable, because it allowed me to use reduced precision arithmetic without a significant penality in compression efficiency. It's so simple, that i could explain it in one short sentence. But i don't want to publish details yet. Sorry... It will take some time until i will (and can) publish any details. Thomas |
