Abstract
Two new fast algorithms for computing the inverse modified discrete cosine transform (IMDCT) as used in the adaptive spectral entropy coder (ASPEC) [2 ] are proposed. A fixed-point error analysis is presented to determine the number of significant bits required for fixed-point implementations.
