Some specification improvements
Michael Scheerer has following comments on the Vorbis specification after successfully implementing a Vorbis decoder accordign to spec:
- A not actual MDCT link.
Actual is e.g. http://www.digital-audio.net/res/docs/ps/eusipco_corrected.ps
- A decoder side scaling factor described in the paper was proposed for the vorbis decoder, including following code lines: float scale;
scale=4.f/n;
but then never used, because the scale is now done encoder sided.
This should be mentioned in the spec.
- The residue reconstruction after the sentence:
"Packet decode proceeds as follows, matching the description offered earlier in the document."
has at least one curly bracket error in the pseudo code. A developer can't determine, which code block belongs to which curly bracket.
