Overview

The tango.info music database contains a playing duration for some tracks.

The value is stored in the format "<minutes>:<seconds>".

The precision level of the value in the database is 1 second, but since different sources and techniques to obtain the value are used, deviations up to 3 seconds are considered to be within the precision of the database.

Sources

The data is obtained from different sources, among them are:

Pregap

The value can contain the pregap, e.g. for track 02 from

 TRACK 01 AUDIO
   TITLE "Roberto Firpo - Instrumental / Ojos Negros"
   PERFORMER "Roberto Firpo Y Su Cuarteto"
   ISRC ARF049601858
   INDEX 01 00:00:00
 TRACK 02 AUDIO
   TITLE "Roberto Firpo - Instrumental / Don Esteban"
   PERFORMER "Roberto Firpo Y Su Cuarteto"
   ISRC ARF049602807
   INDEX 00 02:44:40
   INDEX 01 02:47:20
 TRACK 03 AUDIO
   TITLE "Roberto Firpo - Instrumental / Un Lamento"
   PERFORMER "Roberto Firpo Y Su Cuarteto"
   ISRC ARF049602806
   INDEX 00 05:39:06

TRACK 20 AUDIO
   TITLE "Roberto Firpo - Instrumental / Milonga Del 38"
   PERFORMER "Roberto Firpo Y Su Cuarteto"
   ISRC ARF043800022
   INDEX 00 48:54:00
   INDEX 01 48:56:54

the duration could be

  • 05:39:06 - 02:44:40 ~ 05:39 - 02:44 = 2:55 or
  • 05:39:06 - 02:47:20 ~ 05:39 - 02:47 = 2:52

Gap position

It has been reported to tango.info:

Prefix on CD. Suffix when ripped to 
individual track files - except last file.

XMCD

According to http://ftp.freedb.org/pub/freedb/latest/DBFORMAT

The comments should also contain the string "# Track frame offsets:" 
followed by the list of track offsets (the # of frames from the 
beginning of the CD) obtained from the table of contents on the CD itself

valid XMCD files contain frame offsets from the beginning of a CD.

The standard does not define whether that is INDEX 00 or INDEX 01 as given in the cue sheets.
