First Things First
Let's get one item out of the way first. This conversion method only works for DRM-Free wma files. I am sure there is a way to convert files with DRM, but I'm not real interested in that and it would probably come with a letter from the RIAA or some similar organization. The conversion method outlined below is mainly for SuperHD music from MusicGiants because almost all of the albums are DRM-Free and at least 24/88.2. As I mentioned earlier, if you have wma files at a lower resolution like 16/44.1 you'll just need to add them directly to your iTunes library and the conversion happens on the fly.
1. A Windows computer or virtual machine of some sort. This is required to purchase the music and convert it for use on your Mac.
2. The Windows Media Audio Lossless to Wave Converter from Microsoft.
3. A SuperHD download from MusicGiants without DRM
Here we go
Initially I wrote up somewhat long instructions with several commands that needed to be run from the Windows command line. Then I came to my senses and decided to create a single file for readers to double-click on that will do the whole conversion for them. If you want the instructions for converting this music manually send me an email and we'll work something out.
Download my zip file. Install the Lossless to Wave converter. Buy SuperHD album. Copy new tracks to C:Music. Run the script file in my download and your done.
Step by Step
1. Download this Zip file containing the conversion tool and my automated conversion script.
2. Unzip the downloaded file and install the Windows Media Audio Lossless to Wave Converter by running the file named wmal2pcm_setup.exe
3. Purchase a SuperHD DRM-Free download from MusicGiants.
4. Create a folder on your C: drive called Music. To do this open My Computer, double-click on your C: drive and create the folder right there. (On Windows XP you can select File >> New >> Folder, once you are in My Computer.)
5. Copy your freshly downloaded SuperHD wma files into this new folder called Music. Don't move a complete folder in here, just copy the wma files to the Music folder.
6. Double-click the other file you downloaded from here named wma-to-wav.bat. This will convert all the music for you and output the new WAVE files into a new folder named music-wav right on your C: drive. As the files are converting you will see the progress of each conversion. When the whole album has been converted the new folder containing all the WAVE files will automatically open up for you to see.
Optional: Once this is done the files will work great on your Mac in iTunes. if you want to take it one step further, I always do, use the Max application to convert the WAVE files to AIFF files. The AIFF files have much better support for meta data and cover art. If you need assistance converting the WAVE files into AIFF files using the Max application please read the following article http://www.computeraudiophile.com/node/519.
