1. A system for processing an audio signal, comprising:
- an interface that receives the audio signal from a sensor coupled to a touch input medium, wherein the sensor receives the audio signal via the touch input medium and the touch input medium includes a touch location input surface of a touchscreen;
a detector that indicates an event where the touch input medium has been contacted at a location on the touch input medium, wherein the event has been captured as an audio signal component of the received audio signal;
a processor configured to perform a joint estimation using a set of audio signal components, wherein the set includes the audio signal component of the received audio signal and performing the joint estimation includes identifying the audio signal component of the received audio signal that is to be at least in part reduced; and
a signal modifier that reduces at least a portion of the identified audio signal component from the audio signal.
