All of them &#8211; so far as I know &#8211; are so old that they are in the public domain.  Of course, if it turns out that isn&#8217;t the case, drop me a line and I&#8217;ll take the files down.  As far as the actual records go, most of them are in good condition, with some notable exceptions.  I&#8217;ll be doing some audio patching and noise reduction to make them listenable, while preserving as much of the original sound and tone as possible.<\/p>\n<ul>Here&#8217;s a rundown of the hardware and software that I&#8217;m using:<\/p>\n<li>AudioTechnica AT-LP2D USB turntable<\/li>\n<li>Apple MacBook Pro (Intel CoreDuo)\n<li>Amadeus Pro from <a href=\"http:\/\/www.hairersoft.com\/AmadeusPro\/AmadeusPro.html\">Hairer Soft<\/a>\n<li>A digital camera to take photos of the record labels.<\/li>\n<\/ul>\n<p>There are some limitations to the system.  The turntable can play back at 33 and 45 RPM, but not 78.  I get around this by recording the discs at 45 and then I use the pitch\/speed adjustment within the recording software to speed up the playback by 173.3 percent.  I generally do two passes of noise reduction, once before changing playback speed, the other after.<\/p>\n<p>If you&#8217;re <a href=\"https:\/\/www.quirkspace.com\/quirkblog\/?tag=78-rpm\">browsing through these files<\/a>, be aware that some of these songs exhibit the casual racism of the early 20th century.  I&#8217;m including these for the sake of a more complete collection, as well as for their anthropological value, but I&#8217;ll try to flag them so that you won&#8217;t get caught by surprise.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In 2009, I&#8217;m going to be posting a bunch of old records from my family&#8217;s collection.
