Another insane pattent. Basicly this means that if you use any freqcuency coefficient to detect an error in coefficients in following blocks, you're screwed ... Of course you need to compare coefficients ... At least, I see no way to do proper error-correction in this area any other way. That they ever allowed such a pattent ... Armin

mp3 decoder patent licensing
by Joe Drew 28 Aug '02

So, Fraunhofer et al have decided to charge $0.75 per mp3 decoder. I am not positive on how this affects users of MAD, but I have a feeling that given the choice they would go after both people like me (users of MAD) and people like Rob (developers of mp3 decoders.) Rob, I sure hope the potentially forthcoming ogg decoder is similar to MAD's current interface. Maybe MAD could be Multi-format Audio Decoder? It'd be nice to have pluggable support in mpg321 for both codecs. -- Joe Drew <hoserhead(a)woot.net> <drew(a)debian.org> "This particular group of cats is mostly self-herding." -- Bdale Garbee

Rob: Where can one get the latest sources? I noticed that you have FTP and a Sourceforge mirror set up, but I would assume these are not the latest (i.e., daily) development sources. Let me know. Thanks. -- Neil Hodge neh(a)attbi.com

Still waiting for help from Rob

This is with reference to the mail I wrote a few days back, asking whether the first 9 bits of an mp3 file represent main_data_begin or main_data_end. Can somebody help me? Rob? __________________________________________________ Do You Yahoo!? Yahoo! Health - Feel better, live better http://health.yahoo.com
