Disclosed is a device having an audio interface configured to generate from the audio signal an outgoing audio signal for supplying to a loudspeaker component. The audio interface is configured, in generating the outgoing audio signal, to apply dynamic range compression to the audio signal. Device software is configured to receive an incoming audio signal and generate an audio signal from the incoming audio signal. The audio signal generated by the software is supplied to the audio interface for outputting by the loudspeaker component and is also used as a reference in audio signal processing. Generating the audio signal comprises the software applying initial nonlinear amplitude processing to the incoming audio signal to modify its power envelope. The modified power envelope is sufficiently smooth to be substantially unaffected by the dynamic range compression when applied by the audio interface. |
