В этой статье мы рассмотрим подробнее
log файл отчета который предоставляет граббер EAC (Exact Audio Copy), рассмотрим какие параметры важны, а какие второстепенны, что в отчете за что отвечает.
Научившись правильно толковать эти данные, вы самостоятельно сможете осмыслить принцип работы граббера EAC, сделать вывод о правильности настроек граббера для каждого лога в отдельности.
И так возьмем лог, тип рипа - image+.cue. Рип сделан версией EAC V1.0 beta 3:
Разделяем отчет рипа Exact Audio Copy на логические блоки.
Зеленным выделены те места, которые важны больше всего,
красным выделены правильные значения (идеально правильные настройки):
Значение
667 является правильным значением коррекции смещения именно для этого конкретного привода. Это значение находится по таблице базы AccurateRip -
http://www.accuraterip.com/driveoffsets.htm.
В данном случае рип снимался в несжатом формате.
В данном случае при снятии рипа происходило сжатие "на лету", с помощью внешнего пользовательского кодировщика (Flac). Если указан строковый параметр, то значения в строке
Selected bitrate не учитываются кодировщиком (не надо обращать внимание на значения).
При правильном рипе Test CRC и Copy CRC должны совпадать. Если не совпадают, то значит были ошибки при снятии рипа.

Эта часть присутствует в логе извлечения только в случае если использовался плагин для дополнительной проверки рипа по базе CUETools DB и отправки данных о рипе в эту базу.
Использование этой опции при снятии рипа крайне желательно, так как при наличии хэш-суммы в логе, подделку (тривиальная правка в текстовом редакторе) легко можно вычислить.
