Yet another lossless audio compressor..., Would it make any sense?

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

Truly speaking I'm little bit impressed. The ratios are very close to MA while providing fast decoding! Thats realy cool ! Can we get alpha version of your TAK to play with?
By the way I advise you to change the name to something else cause the whole name is little bit complicated and further more there were some lossy project called TAC from K+K Research so some people can be confused.

Nice. That's very motivating!

Unfortunately this Alpha version definitely needs some further work, before i want to give it away. It still generates some single bit errors on some files. It's not a conceptual problem, so compression efficiency will not be reduced by the necessary corrections. Furthermore my code for reading the source (wave) files is very rudimentary and could possibly fail on some files. I don't think, that the actual release would make a really good impression.

But i will try to provide a working evaluation version as soon as possible. If nothing unexpected will happen, this should be done in about one month.

TAK was the first thing that came to my mind. And it did fit into the table, so i used it. But confusion with other projects would be bad, so i will look for another name.

Thanks

Thomas
