Перекодирование одиночного lossless аудиофайла во FLAC по CUE-таблице
Материал из Linux Wiki
Версия от 17:28, 6 марта 2009; Rain (обсуждение | вклад)
Скрипт для преобразования одиночного ape-файла, представляющего собой копию диска в отдельные FLAC-файлы с заполнением тегов и именованием файлов в соответствии с CUE-таблицой
- Использование
- cueape2flac "AUDIO FILE.ape" "TEXT FILE.cue"
- Зависимости
- monkeys-audio, flac, shntool, enconv, cuetools
#!/bin/bash
# By Rain ;)
# Usage: cueape2flac "AUDIO FILE.ape" "TEXT FILE.cue"
# Depends on monkeys-audio, flac, shntool

ToDo: для варианта FLAC->FLAC без CUE сделать сохранение тегов, добавить вытягивание CUE из FLAC
