Controlling slew rate

A signal processing circuit having a forward signal path for receiving an input signal and outputting an analogue output signal, the signal processing circuit comprising:

• a first component located in said forward signal path for outputting said analogue output signal;
• a predictor configured to predict a parameter of the input signal related to the slew-rate of the input signal;
• and
• a controller for controlling an output slew-rate limit of said first component based on said prediction of said parameter of the input signal.

An audio processing circuit for receiving an input audio signal and outputting an analogue audio output signal, the audio processing circuit comprising:

• a first component for outputting said analogue audio output signal;
• a predictor configured to predict a slew-rate value based on the input audio signal;
• and
• a controller for controlling an output slew-rate limit of said first component based on said predicted slew-rate value.
