commonly used transforms in audio coding. 1.3 The Need for a Class of New Fast Algorithms There has been a large amount of literature on fast algorithms for the standard filterbanks and transforms used in audio coding [9-15]. However, because of the new application scenarios, these algorithms are not directly applicable for some of the new codecs.

Abstract: This paper describes a novel audio coding algorithm that is a building block in the recently standardized 3GPP EVS codec [1]. The presented scheme operates in the Modified Discrete Cosine Transform (MDCT) domain and deploys a Split-PVQ pulse coding quantizer, a noise-fill, and a gain control optimized for the quantizer's properties.

In audio coding, a modified discrete cosine transform (MDCT) is usually used. It is known that the MDCT can provide critical sampling with good frequency selectivity. With that, it is employed in MPEG-4 advanced audio coding (AAC) system [7]. Very recently, MPEG issued a call for proposal on lossless audio coding for its extension 3.
