Mixing complex multimedia data using tempo mapping tools

A system for mixing complex multimedia data using audio tempo mapping, the system comprising:

• a processor and a memory on a non-transitory computer readable medium, the memory including
• a multi-track digital file of a preselected performance having a plurality of audio tracks that include an isolated instrument audio track containing only audio from an isolated instrument having variations in musical tempo, a digital image file that is synchronized with the variations in the musical tempo, and an emulation audio track consisting of the multi-track digital audio file having the digital image file removed;
• and,
• a variable timing reference track designed and provided for a user for the preselected performance, wherein the preselected performance was prerecorded, and the designing of the variable timing reference track includes creating a tempo map having variable tempos, rhythms, and beats using notes from the preselected performance;
• a transformation module on a non-transitory computer readable storage medium and in operable communication with the processor for transforming the multi-track digital audio file to include a variable gain ratio of (i) the isolated instrument audio track to (ii) an emulation audio track, wherein the emulation audio track represents a subtraction of the isolated instrument audio track from the plurality of audio tracks, and the gain ratio is selected by the user;
• an emulation module on a non-transitory computer readable storage medium and in operable communication with the processor for emulating the performance under a guidance of the variable timing reference track;
• and,
• an image display module on a non-transitory computer readable storage medium and in operable communication with the processor for viewing the digital images synchronized to the variations in the musical tempo using the variable timing reference track.
