An audio processing apparatus includes a noise component extraction unit, a removal unit, and a detection unit. The noise component extraction unit performs noise component extraction processing for extracting a noise component from sound data picked up by a sound pickup apparatus corresponding to an imaging apparatus. The removal unit removes the noise component from the sound data. The detection unit detects a condition of an imaging target from an image captured by the imaging apparatus. The noise component extraction unit performs learning processing for adapting the noise component extraction processing to the sound data picked up by the sound pickup apparatus. The noise component extraction unit changes a speed at which the noise component extraction processing is adapted to the sound data in the learning processing according to the condition of the imaging target that is detected by the detection unit.
