Abstract: Methods and systems are disclosed for signal processing, in particular of an entrainment signal. A signal processing module is described which comprises a first signal input for receiving an input signal x in, a signal output for providing an output signal x out to an output device, and a second signal input for receiving a recorded signal y. The recorded signal y represents a recording of the output generated by the output device. The signal processing module further comprises signal processing circuitry configured to generate the output signal by adding the input signal and a difference α (x ref - y) between a reference signal and the recorded signal: x out = x in + α (x ref - y). The reference signal can be the input signal, the output signal, or an external reference signal. The input signal can be an entrainment signal.
