Following a post on vqf.com forum, I found out that some company called
Adapted Wave Technology is ready to release its audio codec based on
wavelets. They say that this wavelet-based codec is superior to MDCT codecs
by 30-50%.
One sentence caught my attention: "Adapted Wave Technologies holds
exclusive
patent rights for applying wavelet packets to audio applications." - sounds
like a broad patent, doesn't it? :-))
There's also a PDF document describing this technology, get it here:
http://www.adaptedwave.com/AWT_Technology_White_Paper.pdf

For more info, check their website: http://www.adaptedwave.com

I know that there is a question about wavelets in Ogg Vorbis FAQ, and it
says that wavelets are good mostly for transient signals...

Comments?
