Abstract
One embodiment of the present invention sets forth a system that includes a detection device and a processor. The detection device is configured to sense that a handheld device has not been placed on or near a surface. In response to sensing that the handheld device has not been placed on or near a surface, the detection device is configured to transmit an indicator to the processor. The processor is configured to receive a first audio signal, and determine that the handheld device has not been placed on or near a surface by receiving the indicator from the detection device. In response to determining that the handheld device has not been placed on or near a surface, the processor is further configured to apply a compensating function to the first audio signal to generate a second audio signal, and transmit the second audio signal to a speaker.
