1. A method for processing a signal, comprising:

  • receiving one or more acoustic signals captured by two or more microphones on a device;

    receiving an indication of a spatial area within an environment, the indication being received from a user of the device;

    based on the indication, determining adaptation constraints used to steer a beam, the adaptation constraints including constraints used in an audio noise suppression system;

    reducing, using at least one hardware processor, an energy of at least one first acoustic signal component of at least one of the acoustic signals, the at least one acoustic signal being associated with a first source positioned outside the spatial area, the reducing including forming the beam based on the indication, the energy of the at least one first acoustic signal component being reduced for the at least one acoustic signal associated with the first source positioned outside the beam; and

    adjusting a reverberation level associated with at least one second acoustic signal component of at least one other of the acoustic signals, the at least one other acoustic signal being associated with a second source positioned inside the spatial area based on the indication.
