摘要
In some embodiments, to reduce noise from an audio signal captured by the drone using a model of noise emitted by the drone propulsion system set (eg, canceling the drone noise signature from the audio signal) The propulsion system set includes one or more propulsion systems, each propulsion system includes an electric motor, and the noise reduction is applied to each electric motor of the propulsion system set. It is executed in response to voltage data indicating the supplied instantaneous voltage. In some other embodiments, generating a noise model by determining a noise signature of at least one drone based on a database of noise signals corresponding to at least one propulsion system, and based on the noise model A method, apparatus and computer program for canceling a drone noise signature in an audio signal.
