Popis: In systems for High Frequency Reconstruction (HFR) employing harmonic transposition, there is a risk of introducing artifacts due to conflicting design goals for stationary, transient, and periodic signals. We describe a filter bank implementation of the transposer which addresses this problem by window design, frequency domain oversampling, and cross products.
