| - | I used Google's DeepDream processing as an audio effect. Therefore, I export music magnitude spectrogram as RGB channels of PNG images and apply to 'Gradient Ascent' with pre-trained networks to these images. Afterwards, I import these images again and resynthesize them using Griffin and Lim's method. | + | I used Google's DeepDream processing as an audio effect.
