Tonight, I discovered "ultimate analog"; that's what I call it, because it was too compelling to quit listening to, and I never found words to describe it.
Never do I record CD's or LP's at 15 IPS because it's too expensive. Tonight, I found a box of tape on 10 inch plastic reels, it was tape that had been recorded over and erased, therefore can be purchased very cheaply. I had made recordings on this tape at 15 IPS and forgotten about it. While the music came through, the first reel was noisy, but the music came through over the noise. There were 10, 10 inch reels, so I still had a lot of tape to go.
The second reel wasn't noisy, and from the audio, I deduced that I had recorded LP's because of the way the music drew me in, but there was no record noise or "tell tale clicks" that are a dead give away for LP's.
The music was so compelling, that I quit all analytical listening and just went with the flow. First, let us define what music is, it's a part of you; you're inner being, that most personal of selves. It is the most important record of your life, because it celebrates the high times and the low times. When you experience instant recall of those times and places, that is invoked or excited by the music, to the extent that you can visualize the experiences, and even re-live the emotions; that is because the music has resonated your subconscious memory. This was the first time I had heard music that compelling. I listened to one reel after another; going back 50 years in time, seeing the people, events, and experiencing the emotions that made those times.
I played one reel after another till almost day; that is when I began to analyze what had transpired. The terms we use to separate CD's and LP's by calling one digital, and the other analog, had been fused to create one compelling "super audio"; music with the emotion of analog, but minus the pops, clicks, and noise; that was music from CD's that had been recorded to magnetic tape at 15 IPS, and played back; you do the analyzing.
