My new Lenovo laptop came equipped with AVRack Media Player. Evil looking dude. I want to use this program, but I am either in advanced middle age or the early stages of crusty old farhood and my learning curve ain't what it useta was.   If I point my browser at something and wait, a little box pops up to explain what I'm pointing at, but most of the time I don't understand the explanation.

I somehow managed to record my 78 of Frank Sinatra and the Charioteers singing "I've Got a Home in that Rock" as something called a ".wav" file, but:
          1) It has all the snap, crackle and pop of the 78.
          2) I don't know what to do with a ".wav" file.

So: Any help with tutorials or such on using AVRack would be greatly appreciated.   And advice on cleaning up (to the extent possible) the sound on old recordings would be good too. (I've already washed all my 78s carefully with dish detergent and water; maybe that was a bad idea, but it was the best advice I had at the time. And it didn't help much.)

Joe Offer? I'm working on it.
