It can't be a quality thing, because it goes all the way to lossless. As a wavelet codec, it might be slow. Then again a few years have gone by and CPUs are faster now. We'll just have to find out for ourselves. Maybe a general mistrust of open source by commercial companies? Ogg Vorbis is a totally competitive and free alternative to MP3, but only Linux users seem to know about it. Brendan |
