How to convert multiple .caf audio files to .wav?

Question

I have downloaded an iPad app called LaunchPad in which you put sounds into buttons aligned in squares so they can be easily played. The problem is that this LaunchPad app only accepts .wav audio files and all my audio effects are in the .caf format and they are like a hundred sounds. Is there a program to convert multiple files (a whole folder of files) into another format?

Answer 1

You can use afconvert:

afconvert sound.caf sound.wav

This can be run on an entire folder using find:

find /path/to/folder/ -name "*.caf" -exec afconvert {} {}.wav \;

Answer 2

You can use ffmpeg (binary or install with Homebrew):

ffmpeg -i sound.caf sound.wav

This can be run on an entire folder using find:

find /path/to/folder/ -name "*.caf" -exec ffmpeg -i {} {}.wav \;
