Assignee: SNAP INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A method comprising:
training a second convolutional neural network (CNN) using a ground truth input song paired with a modified ground truth output song, wherein the modified ground truth output song is a ground truth output song with added vocal portions and an estimate of a clean loss for the modified ground truth output song;
processing the output image using a second CNN to generate a clean loss, the clean loss indicating an amount of the output image that is not attributed to the accompaniment portion;
training a first CNN based on the clean loss;
receiving an input song comprising a vocal portion and an accompaniment portion;
transforming the input song to an input image, the input image representing the frequencies and intensities of the input song;
processing the input image using the first CNN to generate an output image;
transforming the output image to an output accompaniment, the output accompaniment comprising the accompaniment of the input song.
