Chapter 11Batch ProcessingAbout this chapterCanary’s batch processes provide a mechanism for automatically performingthe same operation on an arbitrarily large number of files and saving theresults. For example, the batch spectrogram process lets you makespectrograms of many files at a time, using a set of spectrogram parametersthat you specify only once. The batch processes available are spectrogram andspectrum calculation, correlation, and file type conversion. All batch processescan run in the background, so you can continue to do other work with Canaryor another application program while a batch process is running.This chapter begins by discussing how to specify input files and outputdestinations for Canary’s batch processes. The remainder of the chapterdiscusses each of the batch processes individually. The batch spectrogram andspectrum processes are included together in a single section on spectrumanalysis.Input and outputFor each of Canary’s batch processes, you must specify which files are to beused as input and where the output files should be saved. The input files mustall be stored in the same folder, and all of the output files will be saved in asingle folder (which must be different from the input folder). This sectiondiscusses those aspects of input and output specification that are common toall four types of batch processes. Later sections discuss each type of processindividually.When you choose Batch from the Process menu, a submenu appears showingthe four types of batch processes (Figure 11.1).Figure 11.1. The Batch Processes submenu.When you select any process from the submenu, a dialog box appears askingyou to select a folder to be used as input to the process (Figure 11.2).
