Preserving old cassette tape recordings

Recently while cleaning my office (an adventure that deserves its own post) I ran across a tub of old cassette tapes that my mom gave me.  Most of them had belonged to my grandmother.   What a variety of tapes there were - my favorites were of my then three-year-old son singing nursery rhymes and telling stories, and another of my older son, who used to babble into a tape recorder instead of cleaning his room - he hated to write letters, and this is how he communicated with his great-grandparents.  There were also our kids' band concerts, a tape my grandmother made of children's songs in which she played on the piano and sang, as well as her funeral service and a recording she'd made of my husband's band from 30+ years ago, among others.  These cassettes are so old, and anyone who has ever dealt with this sight knows why I've been so uneasy about them.






My promise to myself when cleaning the office was that I'd start at the door and work my way around the mess - one item at a time, skipping nothing.  Many things were piled up in the office because I didn't know what to do with them, or I knew what I wanted to do but didn't know how to go about it.  I was about halfway through the room when I came upon the box of cassettes, which fell into the latter category.  I decided it was time for a learning experience.

It actually went easier and faster than I expected.  Typically, the motto "Anything That Can Go Wrong Will Go Wrong" applies to me!  But it was an impressively smooth process.

First, I needed software.  I downloaded the free Audacity program (http://audacity.sourceforge.net/) and installed it.  There were a couple of settings I needed to tweak for recording - first, I needed to set a Recording Device - I clicked the drop down arrow and chose "Line In."


Second, I selected a Recording Level.  I used the slider to set the level at about 75% first - and adjusted after doing a test recording.  I found mine worked best at 100%.


Next, I got my hardware ready - a computer, a Walkman, and a plug.   The whole setup, unimpressive as it is, looks like this:




I used a stereo plug (3.5mm) with two male ends.  I plugged one end into the headphone jack of the Walkman, and the other end into the computer, using the Line-In port with the "sound waves" icon - caution!  Do NOT use the headphone or microphone jack for this - I understand you can damage your computer by doing so.  Because this was new to me, I decided to use my old Vista computer rather than my newer one with all my genealogy files on it.


Next, I selected a cassette tape and put it in the Walkman.  On the Audacity screen, I hit the "record" button, and pushed "play" on the Walkman.  I recorded about 10-15 seconds, then hit "stop" on Audacity and on the Walkman, and played back the digitized file by hitting "Play" on Audacity.   My initial recording was hard to hear, so I adjusted the Recording Level on Audacity, and turned up the volume on the Walkman as well, and made a few more test recordings until I was pleased with the results.

When I was ready to being recording in earnest, I created a new file by going to File --> New in Audacity.  I got a new window.  I noted whether or not the cassette was a 60 minute or 90 minute, and planned to be sitting there when the tape stopped so I could stop Audacity as well - it will keep right on going if you don't, resulting in file sizes way bigger than you might want.  I hit "play" on the Walkman and "Record" in Audacity.  

When the file was done recording and I had hit "stop" in Audacity, I saved the digitized file by going to File-->Export Audio.  Using "Save Project" results in saving as an Audacity format rather than a sound file, which is great if you need to further tweak your results before exporting as a sound file.  But if you want just the sound file, go with Export Audio.



A dialog box comes up which allows adding additional information such as artist and track, which is optional.  Then "Ok."  The file then saves the recording as a .WAV sound file with whatever name you give it, and in the directory of the user's choice.

Audacity does a lot more than this - I found several tutorials on YouTube that showed what could be done with the program.  Someday I'll learn more, but for now, this does just what I need it to do to preserve those old cassettes in a better format.
