I would encourage anyone who wants to download the networks broadband pink noise CD to read the instructions on how to download the CD in the proper format for an ipod.  http://www.websitetoolbox.com/tool/post/danmalcore/vpost?id=1087874&trail=50&highlight=ipod

Part of Rob's comments say:

The file which contains the pink noise has an associated track identifier, as Dan requested, so it can be downloaded to an iPod.  If you plan to download the pink noise to an iPod, pay particular attention to the following.
 
For technical reasons, no hyperacusic should ever work with pink noise which has been converted to an MP3 file.  Why?  When it is converted to this format, all frequencies above 13,000 Hz will be lost.  Far more important, to compensate for the loss of high-end frequencies, those frequencies around 8000 Hz will be significantly louder in the MP3 format.  This is known as emphasis.  Working with pink noise that was converted to an MP3 file will enhance the very frequencies most hyperacusics find so problematic.  Don't do it.  Instead, make sure to convert the pink noise to the WAV or AIFF audio formats.  The iPod supports both formats.

 


Any further questions about this would have to be addressed to Rob.  He is the expert.

vingard,
 
Because the Internet is unregulated, you could download a file which claims to be pink noise and you could end up with who knows what.  Or you could end up with poorly made pink noise.  Or you could be downloading an MP3 file of pink noise to your computer, in which case the kinds of things you might want to avoid would be in play.  The pink noise offered by the Network was made with hyperacusic patients in mind, so if you want to be sure you're working with true pink noise and not "pot luck" pink noise, I'd recommend you order the CD from the Network and then download it to an iPod in either the .wav or .aiff formats.  By doing so, all the digital information on the CD will walk up and shake hands with your iPod.  As an exercise, a couple of us from the studio who worked on the pink noise project for the Network examined several examples of Internet pink noise.  The results were predictable in that what Dr. Jastreboff refers to as "so-called pink noise" was either very poorly made or not even pink noise.  Anyway, you're asking a real good question here and I hope this answer helps.

vingard,
 
The Hyperacusis Network is not set up to offer access to a downloadable version of the file over the Internet.  You've raised an excellent point, however.
