So now I have Audacity installed on my Linux boxes and I can do my audio editing again. I have nothing against running Audacity on my Macs, but it works better on my Linux boxes.
I had a whole bunch of files to edit. Several weeks ago, I attached my Technics turntable to my old RadioShack mixer, pushed that through a USB device I got from ThinkGeek.com a few years ago that doesn't appear to be on sale any more, and then fed that into my MacBook. I used the Audio Record program included with Roxio Toast, and I played my LPs and singles and created AIFF files.
These are LPs that did not make it to CD, otherwise I would have just bought the CD. Australian music from Ignatius Jones - Like a Ghost single and maxi-single, Pardon Me Boys LP, and Peter Scriven's Original Tintookies Soundtrack from the 1960s. Gaye Bykers On Acid's first LP Drill Your Own Hole. Leather Nun's single Prime Mover, so I get the foul B side F.F.A. The double LP An Evening With Groucho. And Jethro Tull's Living In The Past. This did appear on CD, but the original 2CD set is unavailable except for huge amounts of money on eBay, and all that's left is the single CD version that has some tracks chopped out.
I transferred the AIFF files to my Linux desktop and used Audacity to chop them into tracks and save them as WAV files. Then they were folded into my music collection, stored permanently as flacs, and the mp3 versions loaded onto my devices for playing.
And now I can enjoy the music again.
