Abstract
A method for reducing frequency crosstalk in the transmission of digitized audio signals. Signals from partial bands in which spectral components of specific frequencies occur as signal components and signals from partial bands in which spectral components occur as crosstalk components in the stop range, undergo a weighted summation. Following transmission, the partial band signals undergo an inverse operation to weighted summation. The method operates independently of the selected encoding process, and is consequently universally usable.
