はじめに
物理的なCDってそのうち劣化するらしいじゃんってことでCD Manipulatorでimg+cue形式にしてとりあえず取り込んでいるわけですが、せっかく読み込み終わったこのデータをCLIでflacに変換できないものかと思って調べました
色々寄り道したのにシンプルなコマンドになってしまった・・・(初手ChatGPTで失敗した)
環境
- OS
- Ubuntu 24.04
- ツール導入楽ちん、dockerやLinux Containerでもできそう
- Ubuntu 24.04
- 導入するパッケージ
flacabcde
手順
# cueタグが埋め込まれた単一flacファイルに変換する
$ flac -f --best --force-raw-format --endian=little --channels=2 --bps=16 --sample-rate=44100 --sign=signed --cuesheet='hogehoge.cue' 'hogehoge.img'
# cueタグが埋め込まれた単一flacファイルを各楽曲のflacファイルに分割して楽曲情報を埋め込む
# --> `-N`以降はChatGPTに出してもらったオプションで未精査、そのうちアップデートするつもり
$ abcde -d 'hogehoge.flac' -N -o flac -x -a default,cddb,read,encode,tag
- できたら指定したいオプション
- 分割済みflacの出力先dir指定したい
- ファイル名に曲名入れたくない
- CDのデータベースなんとかならんか
実行例(成功)
$ flac -f --best --force-raw-format --endian=little --channels=2 --bps=16 --sample-rate=44100 --sign=signed --cuesheet='20161123 - ningen kaika.cue' '20161123 - ningen kaika.img'
