Metadatics includes a number of configurable preferences which are described below.
Only Save Files That Have Changed - When this is enabled, only files whose save indicator is red will be saved. If the save indicator is green, they will be skipped when saving. Disabling this option will cause even files that have not changed to be re-saved.
Clear List After Saving - When this is enabled, after you perform a save, all of the files will be removed from the list.
Save After Every Change - When this is enabled, files will be saved after every change that is made to them.
Clear List When Adding Files - When this is enabled, when you add additional files to Metadatics, all of the files currently in Metadatics will be cleared first..
MP3 Tag Types To Write - Allows you to select which tag types to write when saving MP3 files. You can select either ID3v2.3 or ID3v2.4 using various text encodings. ID3v2.4 UTF8 is the most current standard. Some older devices may only support ID3v2.3 Latin 1.
Write FLAC Album Artwork In - FLAC has it's own metadata block specifically for images. It is recommended to write images to the FLAC Picture Block. You can also choose to save images in a FLAC file's Vorbis Comments. It is generally not recommended to write images in both, since the images are then redundant.
True Audio Tags To Write - Allows you to select which tag types to write when saving True Audio files. You can select either ID3v2.1 or ID3v2.4.
WAVE Tags To Write - Allows you to select which tag types to write when saving WAV files. You can select INFO Chunk tags and/or ID3v2.4 using various text encodings. ID3v2.4 UTF8 is the most current standard. Some older devices may only support ID3v2.3 Latin 1.
AIFF Tags To Write - Allows you to select which tag types to write when saving AIFF files. ID3v2.4 UTF8 is the most current standard. Some older devices may only support ID3v2.3 Latin 1.
Many audio file types support multiple metadata formats. The read options tab allows you to select which metadata formats to read. Metadatics reads from all tag types, and discards duplicates. You may have a special case where you might need to only read from certain tag types.
Most tag types, like ID3v2 or M4A, are standardized. But other tag types, like Vorbis, APE, and ASF, are not. For these tag types, Metadatics gives you the option to map their tag to the corresponding name in Metadatics. It is generally recommended to leave these as default, unless you have some specific reason to change them.
Read Album Artwork From File - When this is enabled, Metadatics will search for an image file that matches the given format string for every file that you add. If it finds one, Metadatics will use that image file as the album artwork. You can use a * character for wildcard matches, or you can construct format strings based on the file's metadata.
Skip Found Album Artwork When There Is Embedded Artwork - When this is enabled, and the files you are adding already have embedded artwork, Metadatics will skip over album artwork image files that are found.
Pasting Album Artwork - When copying image data to the clipboard, OS X stores the data in TIFF format. When pasting into Metadatics, it must be converted to either JPEG or PNG. This preference pane allows you to choose which format to paste. Additionally, you can select a compression quality level for JPEG.
