How to merge mp3:s

1. Use MediaRage ( http://www.chaoticsoftware.com/ProductPages/MediaRage.html ) to organize all the mp3’s in one big pile in a folder. Make sure that when sorted by name, the mp3’s are in playing order (for example, they would be so if they were called “disk 01 track 01 first track.mp3”, then “disk 01 track 02 second track.mp3”, and so on.)
2. Download mpg123 from Forked.net
3. Unpack and install
4. Open Applications > Utilities > Terminal.app
5. Write ‘cd ’ (without the ’) in the newly opened terminal window
6. Find the folder with the mp3’s, and drag it to the terminal window, and press enter.
7. Type:

   /usr/local/bin/mpg123 -w allt.wav *.mp3

   and press enter
8. Wait. You should be seeing “Decoding of (filnamn) finished.” once for every mp3 in the folder
9. When it’s done, put the wav file in iTunes. If the result is an audio book, take step 10 and 12. Otherwise, you can skip them.
10. In Preferences > Advanced > Importing, choose AAC encoding, press OK
11. Right or ctrl click on the wav file in iTunes and select “Convert selection to AAC”
12. When it’s done, get info on the aac file, and make sure that it’s bookmarked.
