iTunes (and others) let you choose how much compression you want up to none (lossless).

You can choose in iTunes settings, but IIRC lossless files are about 10X the size of the most common mp3/AAC compression files.

The tv guide magazine. Who would ever need that now? The guide is on directv, cable, and on smartphones/tablets.

Close, some lossless formats (Like the open source FLAC, or Apple's ALAC/ALE) reduce the file size by ~ 1/2, w/o any losing data. So closer to ~ 5x the size of a 128Kbs mp3.

1411 kbps for raw CD format, ~ 1/2 for lossless, around 700kbps.

So by the time you get to the higher quality mp3, say 192 or 320 kbps, you haven't saved that much from lossless.

But even if one thinks they can't hear the difference, it's good to keep an original lossless file- you can recreate any bit rate or format from that 'master' later, for whatever purpose.

Can you tell me how to do this inverting and subtraction? Can it be done on iTunes or Audacity? I've already converted my audio files but am curious about what was lost.

When I did convert my music collection, I did a test where I'd take the uncompressed song and compare it with the compressed mp3 file using headphones. I determined that, when I was using headphones and listening closely, I could tell a difference, but it was very minor. On some songs, I could not make out any difference, though.

I determined that, when I was using headphones and listening closely, I could tell a difference, but it was very minor. On some songs, I could not make out any difference, though.

I used Audacity, so it looks like you are set.

1) Load the original WAV or FLAC in one set of stereo tracks

2) Load the compressed file in a 2nd set of stereo tracks.

3) Invert one set.

4) Mix and Render. Play the result.

I just did a test on Jeff Beck's Goodbye Pork Pie Hat, but just used a high quality compression versus low quality (the original FLAC is on another drive in the other room, and I am lazy). I got mostly weird cymbal crash sounds and some other drum hit sounding things.

As I said earlier, it's actually tough for me to hear the difference in an A-B, but it does seem to become noticeable to me over time. Apparently, all that stuff missing from the sound just makes it kind of life-less. Some kinda spooky echo-y sounds too.

I've heard some people say this is just phase-shift, that you wouldn't hear it as a difference w/o that reference. Maybe, but when I zoom in bit-by-bit, the phase relationships look extremely close. And some of these difference amplitude are about half scale. That would take a full 90 degree phase shift.

It could be in my mind, it's pretty hard to really test this thoroughly. I suppose I could have a random playlist selection, note my impression after 20 minutes, and repeat that a bunch of times and see if I guessed right. But that would be work, and the extra disk space really isn't an issue for me, and I'd want to keep the raw original anyhow if I had to re-encode. So I just listen to FLAC normally, except when I move something to a portable player for causal use.

I still have mine from 1997. Works fine. Almost never watch it, except for Olympics and such. It's in the spare room, where it doesn't take up valuable space in the living room.

He says "zapped you 3 times, 160, 140 and 110" (all in KPH). He says "license and registration please", she hands it over. He says "you're an RCMP sargeant?" She says "huh?". He says "slow down". At the time she was a civilian employee of the RCMP. Says she may have had too many pieces of paper with the license and registration, DW says "did he get a date?".

DD's name is Mary. Her friends call her Andretti.
There's a hill in Saskatchewan? Who knew! LOL

Windows Fax and Scan software is includes in all of the windows 7 versions. As long as you have supported hardware, here is a link to set it up.

Set up your computer to send and receive faxes

Eliminating wear & tear comes close, but we've always taken better than average care of our vinyl, and offhand I can't think of one that we've had to replace for wear & tear (other reasons, yes, but not w&t).

+1 We just bought a new refrigerator, and DW insisted on saving the $200 for an automatic icemaker + added energy cost.

We would if the phone company hadn't changed the dialtone to digital-only. We held out until we had to make an outgoing call one day...

Don't have a wind-up clock, but I have & use a wind-up pocket watch. (Does that kill 2?)

I'm with ya on everything else except maybe the typewriter. We have one, but haven't used it, and I admit I have been seduced by the dark side of MS Office...

I, also, still use ice cube trays and the yellow pages along with my LPs and CDs. I don't think I will ever be willing to store anything important in the cloud.

Since everything I've ripped to iTunes is from CD's I own, I'll always have a lossless source, don't need another taking up filespace on my HD, iPad, iPods...what am I missing?

Thanks. My computer does not have a FAX modem. Maybe one more thing to add to the list.
