Test File Type

This function is used to modify the action test state based on files being one of a specified list of audio types. You can test if any file is one of, all files are one of or no file is one of. You can also specify that the result is to be SET, ANDed or ORed to the action test state. When running grouped, the any file is one of and all files are one of modes are equivalent.

When testing for MPEG-4 files you can match All, AAC or ALAC files. When testing for OGG files you can match All, Vorbis or Opus files.

You can choose to save the per file results of the test to a track variable. When setting a track variable, the SET, AND, OR semantics are applied. The result stored to a track variable will always be a 0 or 1. Note that regardless of the test type, the per file results are based on matching one of the specified file types. ie. before applying the SET, AND, OR semantics, a per file result is true if it matches one of the specified types.


Specifying the File Types at Runtime

If Determined at runtime is enabled, you list the filetypes you wish to test in a specified named variable. File types are delimited by newline characters (\n), commas (,), or the default list delimiter (\~). The file types are case insensitive and can be any of: AAC, AIFF, ALAC, APE, DFF, DSF, FLAC, MPEG-4, MP3, OGG, OPUS, VORBIS, WAV, WAVPACK.

If more than one of MPEG-4, AAC and ALAC is specified only the last will be used.

If more than one of OGG, VORBIS and OPUS is specified only the last will be used.
