Erratum_______________________________________________________________________________________ Correction to “An Efficient Implementation of the Forward and Inverse MDCT in MPEG Audio Coding” Vladimir Britanak and K. R. Rao In the above paper,1 errors in the expressions of the forward and inverse 9-point DCT/DST modules (p. 51) have been found. In the following are presented only the correct versions of erroneous expressions. Forward 9-point DCT/DST (DCT-II/DST-II) Module

CII5 = SII3 = a25 0 m9

:

Inverse 9-point DCT/DST (DCT-III/DST-III) Module

a10 = a2 0 CII7 a24 = a14 + a17 x2 = a24 + a20

The authors would like to thank D. Watola, Broadcom Corporation, for pointing out these errors.
