Audio stem identification systems and methods

Abstract:

Methods, systems and computer program products are provided for identifying an audio stem. Audio stems (t.sub.1, . . . , t.sub.N) are stored on a stem database and songs (S.sub.1, . . . , S.sub.P) made with at least a subset of the plurality of the audio stems (t.sub.1, . . . , t.sub.N) are stored on a song database. At least partially composed song (S*) having a predetermined number of pre-selected stems (k) are received. In turn, a probability vector (or relevance value or ranking) is produced for each stem (t.sub.1, . . . , t.sub.N) to be complementary to the at least partially composed song (S*).
