转换需要用到下面这些软件,通过brew安装:
brew install flac shntool cuetools ffmpeg
比如转换带cue的wav格式音乐:

luohui@MacBookPro:/Volumes/DATA HD/music/APE/李荣浩《李荣浩创作精选》$ shntool split -t "%p-%t" -f lrh.cue
enter input filename(s):
lrh.wav
shntool [split]: warning: discarding initial zero-valued split point
Splitting [lrh.wav] (69:04.36) --> [李荣浩-李白 .wav] (4:34.33) : 100% OK

Splitting [lrh.wav] (69:04.36) --> [李荣浩-什么都没留.wav] (4:14.47) : 100% OK
Splitting [lrh.wav] (69:04.36) --> [李荣浩-两个人 .wav] (4:50.46) : 100% OK
Splitting [lrh.wav] (69:04.36) --> [李荣浩-有一个姑娘 .wav] (4:45.69) : 100% OK
Splitting [lrh.wav] (69:04.36) --> [李荣浩-都一样 .wav] (5:04.08) : 100% OK

这样就成功的把一个600多M的音乐分割十来个小文件了。

但是ape格式的在mac上转换不了,提示没有解码器:

luohui@MacBookPro:/Volumes/DATA HD/music/APE/莫文蔚.-.[滚石香港黄金十年-莫文蔚精选].专辑$ shnsplit -t "%p-%t" -f mww.cue   -o flac
enter input filename(s):
mww.ape
shnsplit: warning: failed to read data from input file using format: [ape]
shnsplit:          + you may not have permission to read file: [mww.ape]
shnsplit:          + arguments may be incorrect for decoder: [mac]
shnsplit:          + verify that the decoder is installed and in your PATH
shnsplit:          + this file may be unsupported, truncated or corrupt
shnsplit: error: cannot continue due to error(s) shown above

这个时候可以使用ffmpeg先转成flac,再分割:

luohui@MacBookPro:/Volumes/DATA HD/music/APE/莫文蔚.-.[滚石香港黄金十年-莫文蔚精选].专辑$ ffmpeg -i mww.ape  mww.flac

然后再做分割:
