Subtract

input files : source soundfile
destination soundfile

output file : result.wav (default)

processing mode : global

This option can be used to compare (by subtracting) the contents of the destination soundfile with the contents of the source soundfile (if either the source or the destination soundfile is not specified an error message is generated). If the compared soundfiles do not have the same length, the output file is trimmed to the shorter one. Whether or not a block of samples is selected, the difference is evaluated for an entire soundfile.
