1. A system for processing an audio signal, comprising:
- an interface that receives a source audio signal to be rendered by a touch input medium;
a detector that indicates an event where the touch input medium has been contacted at a location on the touch input medium such that rendering of the source audio signal by the touch input medium is affected by the contact;
a sensor interface configured to receive a detected audio signal from a sensor coupled to the touch input medium, wherein the sensor interface is configured to receive signals from a plurality of sensors; and
a signal processor that modifies at least a portion of the source audio signal based on an expected effect of the contact on the touch input medium determined using the indication of the detector, wherein the expected effect of the contact is determined at least in part by comparing the source audio signal with the detected audio signal and comparing the source audio signal with the detected audio signal includes determining a difference between the detected audio signal and the source audio signal.

Abstract
Processing an audio signal is disclosed. A source audio signal to be rendered by a touch input medium is received. An indication of an event where the touch input medium has been contacted at a location on the touch input medium such that rendering of the source audio signal by the touch input medium is affected by the contact is received. At least a portion of the source audio signal is modified based on an expected effect of the contact on the touch input medium determined using the indication of the detector.

19. A method for processing an audio signal, comprising:
-
receiving a source audio signal to be rendered by a touch input medium; receiving an indication of an event where the touch input medium has been contacted at a location on the touch input medium such that rendering of the source audio signal by the touch input medium is affected by the contact; receiving a detected audio signal from a sensor coupled to the touch input medium, wherein the detected audio signal from the sensor is one of a plurality of signals received from a plurality of sensors; and using a processor to modify at least a portion of the source audio signal based on an expected effect of the contact on the touch input medium determined using the indication, wherein the expected effect of the contact is determined at least in part by comparing the source audio signal with the detected audio signal and comparing the source audio signal with the detected audio signal includes determining a difference between the detected audio signal and the source audio signal. - View Dependent Claims (21, 22, 23, 24)

20. A computer program product for processing an audio signal, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
-
receiving a source audio signal to be rendered by a touch input medium; receiving an indication of an event where the touch input medium has been contacted at a location on the touch input medium such that rendering of the source audio signal by the touch input medium is affected by the contact; receiving a detected audio signal from a sensor coupled to the touch input medium, wherein the detected audio signal from the sensor is one of a plurality of signals received from a plurality of sensors; and modifying at least a portion of the source audio signal based on an expected effect of the contact on the touch input medium determined using the indication, wherein the expected effect of the contact is determined at least in part by comparing the source audio signal with the detected audio signal and comparing the source audio signal with the detected audio signal includes determining a difference between the detected audio signal and the source audio signal.
