• musical piece (=wave form equal tracks)
  • The most useful definition of piece depends on the application. One application is listening, for which only a definition based on solely audible content is useful. Waveform equality is not one, since waveform inequality can be unaudible, e.g. phase alterations. One useful definition (especially for the application of DJing i.e. playing for group dancing) is "unique track content", where unique means distinguishable by ear from every other track's content except in parameters that are presentational, e.g. overall gain; silence at start and end. Note that by this definition, piece identity is subjective, due to the "by ear" element. If any listener is found to be able to distinguish two tracks previously designated the same piece, then those tracks must be redesignated as distinct pieces. Chrisjjj
  • I think each piece should have a unique ID I'd like there to be a central shared database of pieces, which could accept collarobative contributions, but under strict guidelines for the process of determining a piece. A problem is: how to let people discover the piece of an unlisted track, unless by letting them listen to the listed pieces. Chrisjjj
