Thanks chas_m,
I think you're right about Audacity being overkill for what I'm trying to do. Instructions for using it are full of technical terms I know nothing about.
I just want to send audio from my stereo amplifier (playing turntable, reel-to-reel, CD, or cassette players) into my computer, separate the songs, and save them to a file in digital format (preferably mp3) where I can change the names from Track 1, Track 2, etc. to the actual names and artists. Then draw from the music to create CDs. With my old Musicmatch Jukebox, I could also post a picture of the artist or album to the file but that's not a major deal. Feeding the music in, separating the songs, and storing them in a file (I don't think I'm ready for the icloud thing yet) so I can use that file as my music library for creating CDs is what I'm trying for. From this explanation, do you think that Piezo or Audio Hijack Pro you mentioned might be the answer?
Thanks again for your interest in helping.
