qaac の準備が面倒くさいのでスクリプト化した

Linux で iTunes の AAC/ALAC エンコーダーを使うために WINE 経由で qaac を使うんだけど、qaac の準備がめんどくさかったのでスクリプト化した。

Linux で qaac を使う方法は過去記事参照。

qaac のバージョンは執筆時点では 2.64。引数に Windows 用 iTunes 64-bit 版のインストーラーを指定すればいいだけにしてある。

2.64 固定番と最新版の2種類がある。git ls-remote で最新のタグを拾おうかと思ったけど、GitHub の API で最新版の名前と URL が取得できたので jq で済ますことにした。

• p7zip、curl が必要。latest の場合は jq も必要。
• 2.64 固定番で qaac のバージョンを上げたければ QAAC_VERSION と QAAC_SHA1SUM を変更する。

■ 2.64 固定版

$ git clone https://gist.github.com/mattintosh4/d5116168d0743d437ea1150cf11588d7 qaac_builder
$ cd qaac_builder
$ bash qaac_builder_2.64.sh ~/Downloads/iTunes64Setup.exe

■ 最新版

$ git clone https://gist.github.com/mattintosh4/d5116168d0743d437ea1150cf11588d7 qaac_builder
$ cd qaac_builder
$ bash qaac_builder_latest.sh ~/Downloads/iTunes64Setup.exe

WINE で qaac64.exe を実行してエラーが出なければOK。

$ wine qaac_2.64/qaac64.exe --check
qaac 2.64, CoreAudioToolbox 7.10.9.0
libsoxconvolver 0.1.0
libsoxr-0.1.3b1

Docker イメージでも作るかな…。

なお、最新版の JSON は https://api.github.com/repos/nu774/qaac/releases/latest で取得することができる。
