ANALYSIS/SYNTHESIS WINDOWING FUNCTION FOR MODULATED LAPPED TRANSFORMATION

ANALYSIS/SYNTHESIS WINDOWING FUNCTION FOR MODULATED LAPPED TRANSFORMATION

There are provided methods and apparatus for performing modified cosine transformation (MDCT) with an analysis/synthesis windowing function, using an analysis windowing function (40, 50, 60, 70, 90) having a meandering portion (44, 64, 94) which passes a linear function (40', 60') in corre...

Zusammenfassung:There are provided methods and apparatus for performing modified cosine transformation (MDCT) with an analysis/synthesis windowing function, using an analysis windowing function (40, 50, 60, 70, 90) having a meandering portion (44, 64, 94) which passes a linear function (40', 60') in correspondence of at least four points (#1, #2, #3, #4).
