Automatic and interactive mashup system

A system for combining audio tracks, the system comprising:

• at least one processor;
• and
• a memory storing instructions that, when executed by the at least one processor, causes the system to perform a set of operations, the set of operations including:
• receiving a first audio track and a second audio track;
• separating the first audio track into a vocal component and one or more accompaniment components;
• separating the second audio track into a vocal component and one or more accompaniment components;
• determining a structure of the first audio track and a structure of the second audio track;
• aligning the vocal component of the first audio track and one of the one or more accompaniment components of the second audio track based on the determined structures of the tracks;
• displaying, on a user interface, a visualization of the vocal component of the first audio track and the one or more accompaniment components of the second audio track at a first alignment;
• adjusting the first alignment upon receiving, via the user interface, a user input corresponding to a change in an alignment between sections of the vocal component of the first audio track and sections of the one or more accompaniment components of the second audio track;
• stretching the vocal component of the first audio track to match a tempo of the second audio track;
• and
• generating a mixed audio by adding the stretched vocal component of the first audio track to the one or more accompaniment components of the second audio track.

A non-transient computer-readable storage medium comprising instructions being executable by one or more processors, that when executed by the one or more processors, cause the one or more processors to:

• receive a first audio track and a second audio track;
• separate the first audio track into a vocal component and one or more accompaniment components;
• separate the second audio track into a vocal component and one or more accompaniment components;
• determine a structure of the first audio track and a structure of the second audio track;
• align the vocal component of the first audio track and one of the one or more accompaniment components of the second audio track based on the determined structures of the tracks;
• display, on a user interface, a visualization of the vocal component of the first audio track and the one or more accompaniment components of the second audio track at a first alignment;
• adjust the first alignment upon receiving, via the user interface, a user input corresponding to a change in an alignment between the sections of the vocal component of the first audio track and the sections of the one or more accompaniment components of the second audio track;
• stretch the vocal component of the first audio track to match a tempo of the second audio track;
• and
• generate a mixed audio by adding the stretched vocal component of the first audio track to the one or more accompaniment components of the second audio track.
