1. A signal processing method comprising:
comparing a first frequency domain representation of a sequence of power values for respective windows of source input samples of a source input signal with a second frequency domain representation of a sequence of power values for respective windows of target input samples of a target input signal to generate a frequency domain difference representation with respect to spectral profiles of the source input signal and the target input signal, wherein the source input signal has different content than the target input signal;
inverse-frequency-transforming the frequency domain difference representation to generate a dynamic matching modification; and
applying the dynamic matching modification to the source input samples to generate respective output samples of an output signal having the content of the source input signal with the spectral profile of the target input signal.
