[Vorbis-dev] Errata 20150227: Bark scale computation
Due to an error when setting the current TeX version of the specification from the original HTML document, the Bark scale computation in section 6.2.5 erroneously read: bark(x) = 13.1 arctan(.00074x) + 2.24 arctan(.0000000185x 2 + .0001x) Note that the last parenthesis is misplaced. The specification document now uses the correct equation as it appeared in the original HTML: bark(x) = 13.1 arctan(.00074x) + 2.24 arctan(.0000000185x 2 ) + .0001x The copies of spec as they appears on xiph.org should autoupdate with the correction soon.
