Convert all .flac files in a folder to .m4a

This will allow you to play .flac with iTunes.

It does, however, assume you know how to use a command line prompt.

For Ubuntu

sudo apt-get install ffmpeg

For OS X

brew install ffmpeg

For both

Navigate to the directory in your terminal of choice.

for f in *.flac; do ffmpeg -i "$f" -acodec alac "${f%.flac}.m4a"; done
