1. A computer-implemented method for removing noise from audio, the method comprising:

  • building a sound model that represents noises which result from activations of input controls of a computer device;

    receiving an audio signal produced from a microphone substantially near the computer device;

    identifying, without using the microphone, an activation of at least one input control from among the input controls;

    associating a portion of the audio signal as corresponding to the identified activation; and

    applying, from the audio model, a representation of a noise for the identified activation to the associated portion of the audio signal so as to cancel at least part of the noise from the audio signal.
