File Variables
These variables are populated from MusicBrainz data for most releases, without any special Picard settings.
Note
Variables that rely on information from the files (e.g.: _bitrate) are only available for use on tracks with attached files, when running scripts manually on files or in the file naming script.
Warning
Prior to version 2.5 Picard did not support using file variables in tagging scripts.
_bitrate
Approximate bitrate in kbps.
_bits_per_sample
Bits of data per sample.
_channels
Number of audio channels in the file.
_dirname
The name of the directory containing the file at the point of being loaded into Picard. (since Picard 1.1)
_extension
The file’s extension. (since Picard 0.9)
_filename
The name of the file without extension. (since Picard 1.1)
_format
Media format of the file (e.g.: MPEG-1 Audio).
_length
The length of the track in format mins:secs.
