Abstract
In some examples, devices for detecting and measures a ghost echo current in an audio signal are described. For instance, the device may be configured to sample a current of an audio signal, compare with an expected current, and determine an impulse response of the ghost echo current based on the sampled current and the expected current. The device may also be configured to reduce the ghost echo current using the impulse response.
