Abstract: Methods and computer readable medium encoded with computer instructions are disclosed for automatically evaluating music tracks to determine which tracks will be suitable for mixing together, by determining a cost of mixing a current track and each of a number of potential next tracks and comparing the costs. Further, methods and computer readable medium encode with computer instructions are disclosed for automatically optimizing the mix of two music tracks by determining the cost of each of a number of possible mixes and selecting the mix associated with the lowest cost.

Abstract: A mix instructions file for controlling the playback of at least one music track file, the mix instructions file comprising one or more instructions including an indication of the at least one music track file at the point in time when the at least one music track file is to be accessed, and at least one effect for manipulating the playback of the at least one music track file. The indication of the at least one music track file and the at least one function comprise the state of the music mix at the point in time. The mix instructions file comprising at least a first and a second packet, that may be transmitted independently of each other, the second packet holding information about the playback state of the mix at the corresponding end of the first packet.
