22 minutes late. Bitterly disappointed. Kidding of course. Congrats on the big 1.0(.0). Have been watching the development of this with interest, even if I didn't understand any of the technical discussion.
Just Thanks Edit: plz validated news & frontpage mods

All in all, this release came pretty fast, and it's Free Software. Great! Now I just hope someone will port it to unix Aside from that, does lossyWAV compile as a 64-bit program out of the box, or would that need some adaptations too? Also, would a 64-bit build benefit from your ASM optimisations as well? Would upgrading from x87 to SSE improve performance?
Well done Nick, and thank you.Thank you too to all the people who helped with testing.Where's the launch party? Cheers,David.

Hello, I guess this is a beginners question , but when I have a wave-file and use lossyWav.exe, I get an exact copy of the original Wave file. Is this correct?I get no difference if I try "lossyWAV <input wav file> -q 0" or "lossyWAV <input wav file> -q 10" or just "lossyWAV <input wav file>". I always ends up with a new file with lossy.wav filetype, but the exact same file-size as the original.Balnes
Hallo Nick,I've just come home from the extended weekend and seen the good news.Congratulations, and thank you very much!
The WAV file then requires to be encoded with a compatible lossless codec, e.g. FLAC, TAK, WavPack, taking care to set the block size to 512 samples (-b 512 in FLAC) and also to preserve WAV chunks (--keep-foreign-metadata in FLAC).
Please explain why. A flac will be generated anyway. What are the risks when I don't keep that metadata ?

So, sadly, that's another way to mislead people. Well, it's not your fault.
