A process and system for dynamically compiling a partially interpreted method is provided. A set of bytecodes for a method is interpreted within a virtual machine. During the interpretation of the method, it is determined, according to the satisfaction of predetermined criteria, that the method contains an execution hot spot and should be just-in-time compiled (JITed) in order to increase the processing speed of the method. The interpretation of the method is halted with a halted execution state and at a halted execution location. Another method is constructed using information from the partially interpreted method and its execution state. The newly constructed method is just-in-time compiled and invoked in such a manner that the newly constructed method recreates the execution state of the partially interpreted method. Once the newly constructed method recreates the execution state of the partially interpreted method, the execution flow follows the bytecode sequence of the partially interpreted method.

The device calculates a first frequency-dependent useful signal level estimator for the frame. The transfer function of a first noise-reducing filter is determined on the basis of the first useful signal level estimator and of a frequency-dependent noise level estimator. A second frequency-dependent useful signal level estimator for the frame is then calculated by combining the spectrum of the input signal and the transfer function of the first noise-reducing filter. The transfer function of a second noise-reducing filter is determined on the basis of the second useful signal level estimator and of the noise level estimator. The latter transfer function is used in a frame filtering operation to produce a signal with reduced noise.
