周末整理音乐收藏

终于把所有的无损收藏都变成flac了，ape本来没啥不好的，但是几乎所有的便携播放设备都不支持。又创新打算出支持flac的播放器了，又可能败一只，所以就折腾了一下。其实人倒是没怎么动手，不过我弱弱的旧笔记本可是忙了好半天呐……

Convert all ape files to flac

find $PWD -iname '*.ape' -print > todo

while read p ; do

  f=`basename "${p}" .ape`
  pn="${d}/${f}.flac"

  echo "start converting \"${p}\" to"
  echo "  \"${pn}\" ..."
  sleep 1
  mac "${p}" - -d 2>/dev/null | flac -o "${pn}" -
  echo "${p}" >> finished-convert
  echo "converted \"${p}\" to "
  echo "  \"${pn}\" ...";

  find "${d}" -iname '*.cue' -print > tmp
  while read f; do
    echo "fixing \"${f}\" ..."
    cp "${f}" "${f}.orig"
    sed -i 's/ape/flac/g' "${f}"
    addsig.py "${f}" # add UTF-8 BOM so that foobar2000 can read it correctly
    echo "fixed \"${f}\" ."
  done < tmp
  echo "${p}" >> finished-fix-cuesheet

  rm -v "${p}"

Python script to add UTF-8 BOM
