Chapter 11: Batch ProcessingInput specificationWhen you select Correlator from the Batch submenu, Canary prompts you fortwo sets of input files (Figure 11.5), which may be the same. You specifywhether you want to correlate waveforms or spectrograms using the radiobuttons at the bottom of the dialog box. (Although the prompt next to thebuttons is “File Contains:”, a file could contain both a sound and aspectrogram, if it’s a Canary-format file.)Figure 11.5. The first input selection dialog box for the batch correlator. Thesecond input selection dialog box is identical except for the prompt messageabove the scrolling list of files.One important difference between the batch correlator and the interactivecorrelator (discussed in Chapter 7) is that the input files for batch spectrogramcorrelations must already contain spectrograms; the interactive correlator, incontrast, can automatically make spectrograms from files containingwaveforms only. Thus if you have two sets of sounds on which you want torun batch spectrogram correlations, you should first use the batchspectrogram process to make spectrograms of the sounds. You can then usethe resulting spectrogram files as input to the batch correlator.Canary 1.2 User’s Manual 149
