There is an obvious typo in the 7feb07 edition of

SHELF FILTERS for Ambisonic Decoders



The expression for RB in Eqn 4.4  Aaron Rationalised Rectangular Decoder

has an incorrect sign.

I have uploaded a corrected version.

I apologise for this error in this important document.  Especially as its the only clear (??) and correct statement of the full horizontal Ambisonic decoding equations in the known universe.[*]  Mea maxima culpa


[*]	OK, there is one other.  "Localization in Horizontal-Only Ambisonic Systems" - Benjamin, Lee & Heller.  AES San Francisco oct06
