Hi all.. I'm a final yr. student at Cardiff University, UK doing BEng Electronic Engineering. My final year project was supposed be a MP3 digital audio player. The idea was to stream the file down to a TI DSP board and decode it and play music.. like in a portable MP3 player. Now, obviously you guys are aware of the MP3 standards complications and since this is a uni. project, the funds are limited. So I've suggested switching to Ogg Vorbis to my supervisor and he will agree to idea upon getting sufficient proof that the project is viable. So I'm asking u experts out there, whether this can be done. I would need the spec. and other documents so forth. I know I'm being very vague, but I'm new to digital audio and digital signal processing and I would be grateful if anyone could help me with this. I think this project might yeild some substantial results for the vorbis community. Who knows... 2-3 yrs down the line, there would be vorbis content streaming down to mobile phones... Thanks for your time... I look forward to getting some feedback/useful info soon...

It was really designed with software decoding in mind. In particular you need more buffers, lots of memory for tables and more flexibility in general. But it sounds like you're talking about a dsp rather than a gate-level implementation, so that might be much easier. Unfortunately there's no spec at this point. You'd have to read the reference implementation and work from there. Maybe someone with more experience with dsp programming could comment further. Hope that helps, -r --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

Now, obviously you guys areMake sure first that you can do it with a C3x or C4x board -- you'll want a floating point chip for a school project. :) --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.
