1. A computer-implemented method for modifying a sound included in an audio signal, comprising:
determining, for each sound included in a plurality of sounds included in at least one audio signal, one or more classifications associated with the sound;
selecting a first frequency sub-band of a first sound included in the plurality of sounds based on a first classification associated with the first sound; and
modifying the first frequency sub-band of the first sound, to generate a modified first frequency sub-band; and
generating a second audio signal by combining the modified first frequency sub-band and an unmodified version of a second frequency sub-band of the first sound.
