[vorbis-dev] Some Questions

[Kim Kyung-wook]

Dear, Stephen.

Oh..Really...I didn't know you developed DCT based codec...I went to the 
archive site of "Tarkin Project"...there was some discussion about Wavelet 
Transform...so I guessed Wavelet Transform was used for this 
project....Still....I would like to know how your project codec perform 
againt H.264 codec...If possible..

Thanks.
