Chapter 5: Multi-track Documentson will be saved into the file you specify. The tracks in the new saveddocument will be in their original order, but will be renumbered consecutivelystarting at Track 1.Files saved in SoundEdit format cannot have more than two tracks.Multi-track correlationsCanary’s correlator can be used to generate cross-correlation functions ofwaveforms or spectrograms of individual tracks within multi-track files. Youcan calculate cross-correlations of tracks within a single file by simplyselecting the same file as both the first and second inputs to the correlator. SeeChapter 7 for discussion of the correlator.Multi-track correlations (i.e., correlations in which at least one document is amulti-track document) are displayed in a multi-pane correlation windowshowing all possible cross-correlations (Figure 5.5).Figure 5.5. A correlation window showing the three correlations obtained bycorrelating a three-track file against itself. The number after “WVF.” in the titleassigned to each pane indicates which tracks are used in the correlation.For correlations of a file containing N tracks with itself, the number ofcorrelations shown is 1/2[N(N-1)].
