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

If none of the moderators object, you can use the Uploads section of HA and give a link to the archive in a post here.

This development is really interesting. Personally, I think a collaboration will benefit both the community and yourself more than doing a one man show. If (for example) FLAC can benefit from your findings, you already have a well-known and quite established format to put in your CV.
