abcde – 嫉妒就是承认自己不如别人

abcde

　　最近玩儿无损，据说有人曾说无损是种生活，是吗？上帝知道，烧友知道，我知道，你知道吗？
　　今天来了兴致，想把自己的几张Avril的碟子给榨出来。Google了一小下，知道有这么个工具，名字挺有意思，abcde = A Better CD Encoder. 它能从CD中rip出来波形文件（WAV），然后根据选项把波形文件转换成特定格式的音频文件，比如mp3, ogg, flac等等。flac = Free Lossless Audio Codec，就是我要的无损了。
　　UB/Debian下安装abcde很简单，apt-get abcde就OK了。安装时你可能发现这个东西很小，只有不到2M。其实，abcde只是一个脚本，它利用其它的工具来实现特定的功能。比如利用cdparanoia来生成WAV文件，利用lame生成mp3文件，利用flac生成flac文件，利用mkcue生成cue文件……因此，如果相应的工具没有被安装，或者路径不在PATH中，abcde就会有错误提示：

[ERROR] abcde: lame is not in your path.
[INFO] Define the full path to the executable if it exists on your system.

这时，安装相应的工具即可。
　　你可以在命令行中为abcde指定选项和参数，但更好的方法是使用配置文件。abcde的配置有/etc/abcde.conf或者~/.abcde.conf(可能需要自行创建)，写好了配置文件，你就可以简单地执行abcde进行工作了，当然你仍然可以使用命令行选项来覆盖配置文件中设置的相应选项。abcde有哪些选项，配置文件如何写，请man之，Google之。这里有个帖子，里面有多个配置文件，包括MP3/ogg/AAC/FLAC/MPP/SPEEX，还有一个同时生成各种音频格式的配置。这里把生成FLAC文件的配置些出来，若要同时生成.cue文件（几乎是必需的），执行abcde时只需要

abcde -1 -o default,cue

当然，mkcue必须已经安装。
