Как извлечь детали из mp3 файла?

Question 1

Как извлечь детали как местоположение песни, художника, альбома, скорости передачи, год, жанр.. и т.д. с помощью команды Linux? Я попробовал mp3info, но он не дал много информации. Помогите.Спасибо!

Question 2

Вы читали man mp3info? Это говорит, частично:

     -p "FORMAT_STRING"

          Print MP3 attributes according to FORMAT_STRING.  FORMAT_STRING is similar to a printf(3) format string in that it is printed verbatim except  for  the
          following conversions and escape sequences. Any conversion specifier may optionally include the various alignment, precision, and field width modifiers
          accepted by printf(3).  See the EXAMPLES section below for examples of how format strings are used in mp3info.

Question 5

Можно использовать mediainfo:

sudo apt-get update && sudo apt-get install mediainfo

можно извлечь все виды информации с помощью --inform='<category>;%<parameter1>%[%<parameter2>%, ...]' опция; <category> строка, представляющая категорию параметров, и <parameterN> строка, представляющая параметр в той категории; и категории и доступные параметры могут быть перечислены путем выполнения mediainfo --Info-Parameters; например, для извлечения альбома и заголовка дорожки в Album - Title формат:

mediainfo --Inform='General;%Album% - %Title%' track01.mp3
