Kompression

Is life losing fidelity ? I mean fidelity in a audio terminology .. as in Hi Fidelity.
MP3s are compressed audio files, and audiophiles assure us after conducting double blind listening tests that a well encoded mp3 file sounds identical (to most people) to the original CD. And they are the experts - who am I to question a study conducted using the scientific method ! But then, anyone who has ever heard a live concert can tell you that no CD can reproduce it. I guess the live concert is more than just the music. There are those vibes you get from the people around you, the memories of the last time you heard the song which you share, the inevitable joint which is passed around. You look up at the sky (when was the last time you did that ?) and try to imagine what this concert is in context of the universe. Or maybe the concert is the whole universe at that instant.
Coming back to the mp3 file. It loses something. I have tons of music as mp3s. They are convenient, you can easily find what you need to play by doing a simple file search. What it takes away is the randomness of browsing a CD tower (hey .. i have owned LPs, but only in very limited quantities. and any LP fellow will tell you that Cds suck too. but, just as a baseline, lets go with CDs) looking for the next song to play. And discovering that Allman Brothers recording that you had not heard for years.
Are we consciously trading fidelity for convenience? It may be a natural progression - we want to experience so much in life that the only way is to compress those sensations, in terms of time as well as quality. Think about it .. 10 years ago, would i have had access to so many different genres, so many different artists ? So we trade in quality for variety. And maybe our lives are richer because of that.
Same with images. Instead of film, we have jpegs. Which allow us to capture 200 pictures in the time we took to shoot 20. We still sacrifice fidelity. Even with the so called RAW. Its bits after all .. and whatever the resolution, there is no digital format which can accurately reproduce analog. It will be almost similar .. with no discernible loss in quality. Discernible. What a concept. When we move towards low-fi, thats the first one that comes up. No perceptible difference. We train ourselves to ignore it. Our perceptions become coarser and coarser. Part of evolution !
My life today can be encapsulated within the 0.5"x3"x 5" confines of a 120 Gb portable hard drive. That will be more than enough to store all relics of my existence. And most of that will be the images that i have generated using increasingly sophisticated digital cameras, 99% of which count for nothing. I realized this when i was trying to catalog my belongings, as a prelude to moving out of my residence of the last 5 years. I tend to be attached to paper (magazines, old letters - the paper versions, receipts), but the bulk of that is more than 5 yrs old. All the recent stuff is mostly digital.
Makes you realize how fragile all these memories are. I can stomp on this hard drive and make my life vanish. I will then remain as bits (and bytes) in other peoples mind. Or their hard drives.
