Patent ID: 8476517

Claim:
A variable timing reference system for isolating and mixing audio tracks from a pre-recorded musical work, the system comprising: a processor and a memory on a non-transitory computer readable medium, the memory including a pre-recorded, multi-track recording on a non-transitory computer readable storage medium, the pre-recorded, multi-track recording having an isolated instrument audio track that is separable from the remainder of the pre-recorded, multi-track recording for emulating by a user of the system; and, a variable timing reference track designed for use in the emulating of the pre-recorded, isolated instrument audio track when the pre-recorded, isolated instrument track is separated from the pre-recorded, multi-track recording; and, a transformation module on a non-transitory computer readable storage medium and in operable communication with the processor, the variable timing reference, the pre-recorded, multi-track recording, and the pre-recorded, isolated instrument audio track for independently adjusting track volumes between at least two tracks within the pre-recorded, multi-track recording; wherein, the variable timing reference track included in the pre-recorded multi-track recording enables the isolation and mixing of tracks, or portions of tracks, in the pre-recorded multi-track recording, to facilitate the separating and emulating of the pre-recorded, isolated instrument audio track when separated from the pre-recorded, multi-track recording.
