Abstract: A directional recording method includes: generating an initial sound pickup beam by using a beam forming algorithm, where the initial sound pickup beam points towards the target acoustic source; recording an initial pointing direction of the initial sound pickup beam; and detecting that a direction towards which the recording device faces changes, and adjusting, according to the change of the direction towards which the recording device faces, the initial sound pickup beam to obtain a target sound pickup beam, where the target sound pickup beam points towards the target acoustic source. Compared with the prior art, according to the directional recording method and apparatus, and the recording device provided in the embodiments of the present invention, a pointing direction of a sound pickup beam can be adjusted according to a change of a direction towards which the recording device faces.
