They are not truncated/quantized in integer domain, the coefficient encoder just stops when the specified bit budget limit is reached. So you can define arbitrary levels of quantization. (an advantage of embedded bitstreams - maybe the only one;) Holger --- >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 '[email protected]' containing only the word 'unsubscribe' in the body.
