Abstract

See full text

Disclosed are techniques for preventing extraction of original audio tracks from a song. The techniques are executed on a game platform and involve providing a first and second audio track representing parts of a musical composition, mixing the first audio track and the second audio track to provide a mixed audio track, generating an audio modification data comprising a series of substantially random audio modifiers, and then modifying, before playback, the mixed audio track based on the audio modification data to provide a modified mixed audio track, such that subtracting the second audio track from the modified mixed audio track produces a third audio track with an audibly detectable deviation from the first audio track.
