# file i/o section: read in the .csv file created by Raven from our .WAV files
#
# In Raven, make the waveform window active, then go to File/Export Sound Samples... and save as a .csv file
# These files contain no time information apart from the row number (you need to convert using the sampling frequency,
# which is available in Raven under the file's information); the file is just a 4-column spreadsheet of the 4 channels' sound waveforms
# and digest it to get (time, Ch1, Ch2, Ch3, Ch4) waveform
# Be sure to prefilter files in Raven Pro 1.4 before analyzing them with this program. For our swallow mobbing cries, put them through
# the Tools/Batch Band Filter using the Band Pass Filter from 1.5 KHz to 9kHz. You need to create a directory for the input and output files
# for a batch process, so be careful not to overwrite the original files! Failing to bandpass filter the files will widen the cross-correlations
# due to the much lower signal-to-noise ratio for unfiltered files. For other calls, be sure to get the correct bandpass filter values.
