Abstract (en)

[origin: WO2005078703A1] Disclosed is a method for quantizing a data signal of a sequence of data values, comprising frequency-selective filtering of the sequence of data values so as to obtain a sequence of filtered data values, and quantizing the filtered data values in order to obtain a sequence of quantized data values by means of a quantizing stage function which copies the filtered data values onto the quantized data values and the curve of which is steeper below a threshold data value than it is above said threshold data value.
