Presented below are versions of both the double and single hit Millennium drums. You can read more about their origin in this news article from 2001. You can download them in standard Windows .wav format and also in three differnet bitrate versions of MP3 format, depending upon your the requirements of your application. For example, you may wish to use the MP3 format as an SMS Text Message alert, but the highest quality (224kbps) may not be supported on all makes and models of mobile (cell) phone, so you may require the 160kbps version.
