GENERATION OF OUTPUT DATA BASED ON SOURCE SIGNAL SAMPLES AND CONTROL DATA SAMPLES

Abstract:

A signal processing method, especially for audio signals, comprises: receiving input signal samples having source signal portions associated with respective time periods (In_n-1); generating parameters associated with the respective time periods by processing the respective input signal samples, in which the step of generating the parameters has an associated non-zero latency period so that generating step provides a parameter p in a time period (T_n-1) later than the start of the respective time period; and generating an output data portion associated with a given time period (Out_n-1 using a signal processing function F which depends upon the input signal samples in the given time period (In_n-1) and an approximated parameter p' (1110) associated with a time period other than the given time period (T_n-2).
