Hi, Picked up last night's snap ... Building on my SGI O2 I get a big clipping problem .. Using the encoder_example to encode e.g. a 1 sec 16 bit stereo wav file, when I decode using decode_example I get clipping ... any ideas here???? I can hear the original in the clipped mush! The raw file plays just fine (on the SGI) and I have even decreased the gain to 80% and removed any DC offset (using Soundforge on my PC). regards, Rob. P.S. Am am in big need of 4 channel encoding ... anyone done this yet? +============================+====================================+ | Dr R P Fletcher (Rob) | Email R.Fletcher@york.ac.uk | | Graphics Coordinator | Phone +44 (0)1904 433816 | | Computing Service | Frontdesk +44 (0)1904 433800 | | University of York | Fax +44 (0)1904 433740 | | YORK YO10 5DD, UK | ICQ UIN 4019164 | | URL: www-users.york.ac.uk/~rpf1/ Camera: /~rpf1/robcam.html | +=================================================================+ --- >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.

> >P.S. Am am in big need of 4 channel encoding ... anyone done this > yet?Four channel encoding is actually easy. If you have a file format (for getting the input data from) that supports 4 channels, oggenc would need about 2 lines of changes, plus support for opening/reading from that file format - it's designed such that you should be able to do this sort of thing very easily. Four channel playback is much harder, since there doesn't seem to be a good way of doing this portably, that I know of. Also, you won't be able to use libvorbisfile without some modifications (simple ones, but they would need doing). Simple decoding (to whatever file format you had for the original input data, probably) is also easy.

When I wrote libvorbisfile, it could do four channel... did optimization inadvertantly remove this capability?
