Preferences

Output Directory — The directory where encoded files will be written. If you are using a custom naming scheme with directories, the base directory of the custom naming scheme starts in this directory.

Preserve Input File's Directory Structure — Keeps the directory structure of the files that you add to the queue. For example, if you drop a folder called "Music" that has several sub-folders of audio files, Pro Audio Converter creates a "Music" folder in your output directory and re-creates the same folder structure for the output files.

Overwrite Existing Output Files — When checked, output files that already exist are overwritten during encoding. If not checked and an output file already exists, Pro Audio Converter generates a unique filename by appending a number to the end. For example, if "My Song.mp3" already exists, it would become "My Song 01.mp3".

Prompt Before Overwriting Existing Output Files — If an output file already exists, you are prompted before it is overwritten. You'll be presented with three choices: overwrite the file, don't overwrite (uses a unique filename instead), or skip the file completely. You also have the option to apply your choice to all subsequent files in the batch.

Delete Original — When checked, the original file is moved to the Trash once encoding is complete. If you are only updating metadata, the original file will not be deleted.

Open Output Directory When Finished — Opens the output directory in a Finder window when the entire queue has finished encoding.

Use a Custom Output File Naming Scheme — Lets you specify a custom output file name and folder structure based on properties of the input file. Use keywords enclosed in brackets to build your folder and file structure; the keywords are replaced with actual information from the input file when it is encoded. See Output Directory & File Naming for more information.

Use Two-Digit Track and Disc Numbers — Forces track number, track total, disc number, and disc total values to use two digits. For example, 01 instead of 1.

Write Metadata To Encoded Files — If disabled, no metadata will be added to encoded files.

Rename Files When Updating Metadata Only — When updating metadata of source files, applies the custom naming scheme to the file.

Fallback To Filename When Title Field Is Empty — When using a custom naming scheme, if the Track Title field is empty, Track Title is replaced with the source file's name.

Write "Encoded By" Information To Files — When enabled, Pro Audio Converter writes "Encoded By" metadata to output files.

Write Format String To Comments — Lets you write a string of your choosing to the comments metadata field of the output file. For example, you may want to write the encoder settings used or the source file type the output file was made from.

MP3 Metadata Types To Write — Select which tag types to write when saving MP3 files. You can choose ID3v2.3 or ID3v2.4 with various text encodings. ID3v2.4 UTF-8 is the most current standard; some older devices may only support ID3v2.3 Latin 1.

Preserve Broadcast WAV Data (BEXT Chunk) — If the source file has Broadcast WAV data and the output file is a WAV file, Pro Audio Converter writes the Broadcast WAV data to the output file.

Save Album Artwork To File Named — Saves the album artwork as a file in the same folder as the destination audio file. You can name the file however you like and choose PNG, JPEG, or TIFF.

Read Album Artwork From File Named — When there is no artwork in the metadata, Pro Audio Converter looks for album artwork as a file in the same folder as the source file. Use * as a wildcard in the name; Pro Audio Converter uses the first file found that matches.

Add Encoded Tracks To iTunes Library — Adds supported output files to your iTunes library. Currently supported file types: AIFF, AIFC, AAC, Apple Lossless, MP3, WAV.

Add Encoded Tracks To Playlist Named — Adds supported iTunes tracks to a playlist. You can type in the name of an existing playlist, or use custom naming scheme format specifiers to create playlists based on track information. See Output Directory & File Naming for more on how the specifiers work.

Keep Files In Queue After Encoding — Files are left in the queue once encoding is complete.

Keep Files In Queue After Updating Metadata — Files are left in the queue after updating source file metadata. See Using as a Tag Editor for more information.

Skip Encodings Where The Input And Output Types Are The Same — Skips source files that are of the same type as the destination file. For example, if you are encoding MP3 files, Pro Audio Converter will skip over MP3 source files in the queue.

Maximum Number of Simultaneous Encoders — Sets the maximum number of simultaneous encoding operations. Limited to the number of processor cores your system has. Decreasing this number reduces system load but takes longer to encode a batch.

Show Error Log Immediately When Error Occurs — When checked, the Error Log window is shown as soon as the first error occurs, instead of at the end of the encode process.
