The audio on legacy formats like records and tapes is far from permanent. Heat, humidity, chemical reactions and even gravity are all working to make priceless memories fade away.
Technology is also working against you. Record players are difficult to find as are reel to reel decks. Even relatively recent DAT machines are more uncommon.
We can convert about every format of audio to CD. (Sorry, we don't have a wire-recorder or an 8 track deck.) Popular music isn't really a candidate for this service. The record companies have already done that. We save those personal recordings that can't be replaced. Among the valuable archives we've been entrusted to covert to CD include the personal record collection of President Kennedy for the Florida International Museum, Vietnam era letter tapes for the Smithsonian, personal 78rpm records, cassettes, reel to reel tapes from as far back as 1949 (Paper tape from Germany!) and garage band recordings from the 60s and 70s.
It's always interesting work that takes expertise and digital processing to make voices from the past heard again.
