Convert multiple .wav to .caf
提问by FBryant87
I'm making an iPhone app and I have a ton of .wavfiles I need to convert to .caf
我正在制作一个 iPhone 应用程序，我有大量的.wav文件需要转换为.caf
I can use this for each file:
我可以对每个文件使用它：
afconvert -f caff -d LEI8@22050 walking.wav walking.caf
But that would take ages, so I'm trying to convert all files with:
但这需要很长时间，所以我试图将所有文件转换为：
for i in *.wav; do afconvert -f -caff -d LEI16@44100 -c 1 $i ${i%.wav}.caf; done
But I get this error:
但我收到此错误：
Error: ExtAudioFileCreateWithURL failed ('typ?')
EDIT:The error will actually occur because of a typo in the for loop shown above. It should be caffnot -caff. The correct code snippet would then be.
编辑：由于上面显示的 for 循环中的拼写错误，实际上会发生该错误。应该caff不是-caff。正确的代码片段将是。
for i in *.wav; do afconvert -f caff -d LEI16@44100 -c 1 $i ${i%.wav}.caf; done
There may be other issues and the accepted answer is valid, just wanted to help out with making the question clear. /EDIT

This is the script i have been using, slightly modified from another source, which kindly deserves all credit:
这是我一直在使用的脚本，从另一个来源稍作修改，值得所有赞誉：
##
## Shell script to batch convert all files in a directory to caf sound format for iPhone
## Place this shell script a directory with sound files and run it: 'sh afconvert_wavtocaf.sh'
## Any comments to '[email protected]'
##
for f in *.wav; do
if [ "$f" != "afconvert_wavtocaf.sh" ]
then
afconvert -f caff -d ima4 $f
echo "$f converted"
fi
done
Save this in a file named 'afconvert_wavtocaf.sh'. See if that does the trick.
将其保存在名为“afconvert_wavtocaf.sh”的文件中。看看这是否有效。

Try adding echo $i;before afconvertin your script to get the name of sound file your command fails on. Then try to convert it manually, it will probably fail too.
尝试在脚本中添加echo $i;beforeafconvert以获取命令失败的声音文件的名称。然后尝试手动转换它，它也可能会失败。
I suspect one of your files is not an actual wav, but is in format not recognizable by afconvert.
我怀疑您的一个文件不是实际的 wav，而是 .wav 无法识别的格式afconvert。
