This calculator allows you to enter the running time of digital audio, and it will give you the resultant hard drive storage requirements in many bit/sample rate combinations: 16bit/44.1k, 16bit/48k, 24bit/44.1k, 24bit/48k. Also gives estimates for how many CD-Rs or DVD-Rs it will take to back it all up. (Microsoft Excel required.)

Drag this over your Mac's System Folder (OS 9) and it will be put it in the right place. Then you can search silentway.com from your desktop. Or, see the search page.
