from my old windows computer I have around 20G of music in flac format. Now, I got a mac and I would like to add this music to itunes, so I need to convert them to mp3 format.

So, what is the best way to convert a so big music library to mp3?

The most practical thing to do is not convert it.

A little confused if this was part of the op's question but, would it be possible to play the .flac files on an iPod? – Javed Ahamed Jul 13 '10 at 7:50
Those will not play on an iPod, they would need to be converted to AAC or MP3 first. – James Snyder Jul 13 '10 at 14:04
If you don't need to play them on other devices, also check out flukeformac: – James Snyder Jul 13 '10 at 14:05

For anyone running OS X and finding this question from Google, I would suggest following the method listed here and using ffmpeg in the Terminal.

Install homebrew:

/usr/bin/ruby -e "$(curl -fsSL"

Then install ffmpeg and all its libraries:

brew install ffmpeg

brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-libass --with-libquvi --with-libvorbis --with-libvpx --with-opus --with-x265

Then within the terminal, navigate to the folder containing the FLAC files to be converted and run ffmpeg's converter with something like this:

for q in *.flac; do echo "$q"; ffmpeg -i "$q" -aq 0 "${q%%flac}mp3"; done

Credit goes to the original poster of the above command at the linked thread.

You could convert them to Apple lossless. Or use xIph as Ignacio suggests. I got this link from google: Convert to Apple lossless
