otropy</em> means direction dependence. While the spatial correlation between pixels maintains independently of their direction of an image (<em>isotropy</em>), this is not the case when dealing with spectrogram images. In a spectrogram representation the horizontal axis represents one thing (e.g. time) and the vertical, another (e.g. frequency). Therefore, significant information is lost when translating algorithms from isotropic to anisotropic contexts. In DreamSound, we implemented an audio-specific solu
