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.
