As we are using the term, audio restoration is the process of copying audio (speech or music) from the original media (disc or tape) to a computer’s hard drive, removing clicks, pops, hiss and other noise using appropriate software and then writing the “cleaned up” audio to a CD or DVD. If the original media is a shellac or vinyl record, the first step is washing the disc.
In this revision, I’m separating the text into chapters to make updating easier. I’m also making the chapters available as downloadable Adobe Acrobat (pdf) files so you can easily print the ones you need for later reference. Each chapter will also contain a “last updated” date in the heading so you easily see if you need print or download it.
