Перекодирование одиночного lossless аудиофайла во FLAC по CUE-таблице

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
