 #### FilePresetType
 
 Describes audio format that is used during writing to file as well as encoded final file properties. You can use one of predefined presets, or fully customize the result file, but be aware that the properties aren't limited to only valid configurations, you may find property pairs that will result in error result during recording start (or when enabling the file output during active input session)!
