Abstract: A method of measuring an impulse response of an amplifier coupled in operation to a loudspeaker arrangement includes: (a) coupling directly to a connection between the amplifier and the loudspeaker arrangement for obtaining access to a drive signal (Samp) applied to the loudspeaker arrangement to generate an acoustic output (S2); (b) disposing a microphone arrangement for receiving the acoustic output (S2) of the loudspeaker arrangement; (c) using a test signal generator to apply a test signal (Ssw) to an input of the amplifier; and (d) receiving at a digital signal processing arrangement (DSP, 210) at least the drive signal (Samp) and the acoustic output (S2) corresponding to the test signal (Ssw) and performing on these signals a signal processing operation for determining an impulse response for at least one of: the amplifier, the loudspeaker arrangement.

Abstract: A sound analysis and associated sound synthesis method is provided. A first input sound signal is received and analyzed, to determine its corresponding impulse response representative of a timbre of the input sound signal. A second input sound signal is received and processed into a form which the corresponding impulse response is susceptible to being applied, wherein the processing includes generating a “pink noise” equivalent frequency spectrum of the second input sound signal. The impulse response is applied to the processed second input sound signal to generate an output signal, wherein the output sound signal includes at least timbral nuances of the first input sound signal.
