Query: Modeling the Compatibility of Stem Tracks to Generate Music Mashups   A music mashup combines audio elements from two or more songs to create a new
work. To reduce the time and effort required to make them, researchers have
developed algorithms that predict the compatibility of audio elements. Prior
work has focused on mixing unaltered excerpts, but advances in source
separation enable the creation of mashups from isolated stems (e.g., vocals,
drums, bass, etc.). In this work, we take advantage of separated stems not just
for creating mashups, but for training a model that predicts the mutual
compatibility of groups of excerpts, using self-supervised and semi-supervised
methods. Specifically, we first produce a random mashup creation pipeline that
combines stem tracks obtained via source separation, with key and tempo
automatically adjusted to match, since these are prerequisites for high-quality
mashups. To train a model to predict compatibility, we use stem tracks obtained
from the same song as positive examples, and random combinations of stems with
key and/or tempo unadjusted as negative examples. To improve the model and use
more data, we also train on "average" examples: random combinations with
matching key and tempo, where we treat them as unlabeled data as their true
compatibility is unknown. To determine whether the combined signal or the set
of stem signals is more indicative of the quality of the result, we experiment
on two model architectures and train them using semi-supervised learning
technique. Finally, we conduct objective and subjective evaluations of the
system, comparing them to a standard rule-based system.
