Converting iTunes m4p files

iTunes is great, but purchased software is pretty much useless, since it's not in a portable format - it's in a "purchased (m4p) format. There are ways around this, however.

Converting Itunes protected files m4p to mp3 files

I am a big fan of the iTunes program and I download all my music through iTunes. I also own an iPod but I found it frustrating I could not listen to the music with our in dash MP3 players that we have in our cars. I purchase the music but without the iPod the songs are useless if you want to take it with you. A few searches on the internet turned up partial solutions but I thought I would share the entire solution with you. This process only works if you are the actual owner of the song and have it authorized through iTunes. I am in no way promoting piracy, I bought the songs legally from iTunes.

The process involves two pieces of software to handle the decoding. First you will use "hymn" to turn the m4p (protected) file into a m4a that you can play anywhere. Then you will use dbPowerAMP to convert the m4a into an mp3 file.

1. Download hymn http://www.hymn-project.org/ To make the instructions as simple as possible download hymn and unzip it to the C:\hymn directory. Hymn is a command line tool for windows that is pretty easy to use. There is a GUI available for the MAC.

2. Copy the mp4 files you want to convert to C:\hymn (if you understand windows you can just add c:\hymn to your path, if not don't worry and continue).
open a MS dos command prompt window start>>accessories>>command prompt

3. Run hymn on each of the files you are converting
C:/>
C:/> cd hymn
C:/> hymn thenameofthefileiwantoconvert.m4p

You will need to do this for every file you want to convert or put multiple files in the command line

C:/> hymn filetoconvert1.m4p filetoconvert1.m4p

The m4a files will be created in the same directory. You can use the hymn command line options if you want to send them to another directory.

You are now ready to convert the m4a files to mp3 files. In order to do this you will need a converter. I use the dpPowerAmp converter.

4. Download dbPowerAMP
http://www.dbpoweramp.com you will also need to the m4p codec

5. Download m4p codec (download the decoder)
http://www.dbpoweramp.com/codec-central-mp4.htm

6. From there you can just highlight the m4a files in windows explorer. Right click with the mouse and select the "Convert To" option. Choose the quality and the folder you want to store the mp3's in and click "Convert".

The end product is a mp3 file that you can play anywhere. It is a bit of extra work, but you could possibly automate the process further. It is worth noting that the m4a file still has the original purchasers information in the file. Do not pass these files around to your friends. If they end up on the internet you could be prosecuted for piracy.
