Preface
Analysis and synthesis cosine-/sine-modulated filter banks are perfect reconstruction filter banks that are used for the time-to-frequency transformation of an audio data block, and vice versa, many sub-band/transform-based schemes for high-quality lossy/lossless compression of digital audio signals. These include the modified discrete cosine and sine transforms, the modulated lapped transforms, the extended lapped transforms, the low delay modified discrete cosine transform, the modulated complex lapped transform, and various forms of (low delay) complex exponential-modulated and real-valued cosine-modulated quadrature mirror filter banks. The perfect reconstruction cosine-/sine-modulated filter banks are fundamental processing components in many state-of-the-art international audio coding standards and in proprietary audio compression algorithms, broadcasting/speech/data communication codecs, and open-source royalty free audio/speech codecs. In general, the computation of the complete perfect
