Disclosed are a sound card and a method for limiting inputs to and outputs from that computer sound card. Specifically, the voltage of a feedback connection between the input and output of a sound card amplifier is increased from minimum voltage until an over-saturation condition occurs. This finds the “output voltage limit.” Thereafter, the output voltage of the amplifier is restricted to the output voltage limit. The feedback connection is then terminated and the voltage of the signal being supplied to the amplifier is increased from minimum voltage until the over-saturation condition again occurs. This finds the “input voltage limit.” Thereafter, the input supplied to the amplifier is restricted to the input voltage limit. |
