AB  - Most of the current audio coding schemes use transforms like the Modified Discrete Cosine Transform (MDCT) to calculate a blockwise frequency representation of the audio signal. Since these transforms usually produce oating point values even for integer input samples, a quantization process is necessary to achieve a reduction of data rate. This paper presents a new transform with perfect reconstruction that produces integer output values. The transform is called IntMDCT and is derived from the MDCT preserving most of its attractive properties. It provides a good spectral representation of the audio signal, critical sampling and overlapping of blocks. A lossless audio coding scheme may be built by simply cascading IntMDCT with an entropy coding scheme.
