Default My CDs are Less Dynamic Than My MP3 Downloads

According to this tool(image is representative of interface):

http://blog.son-video.com/wp-content...ns-titre-1.jpg


In nearly 9/10 cases, the above tool returns a LOWER 'DR' value for the CD vs the old MP3 download I'm replacing with tracks from the CD.

I.E. Some old MP3 of a Paul Davis song I bought off Amazon returns a DR value of 12 in Foobar, but both a WAV and MP3 ripped from a 1991 Cool Night CD shows DR-11!

What is going on here?

Musical waveform content missing out of the MP3 ?

** Does the window continuously give the peak and "rms" value of each channel as it plays - then the magic number DR pops up at the end ?

DR cannot be so easily computed from a data stream like the first two as it extends over a period of time plus is partly a matter of judgement.

Not worth worrying about.

Was the source the same for both MP3 download and CD? I do know Amazon offers both CD and MP3 download, but download has been modified/enhanced, because the earlier CD was never remastered.

I like Paul Davis!! Good choice.

Rambling: You MAY remember The Little River Band. I THINK it's their Great Hits CD. But during an Amazon review, someone yelled, the MP3 downloads do not match the CD!! It awakened my curiosity, so I downloaded a few of the MP3s. What had changed, Capitol, LLC (multi-track) remixed the tunes to new stereo. I won't claim they did an excellent job, but the songs SOUND way different. Why I say you must be cautious what you are listening to.

So, after someone was ****ed (in usenet)that I never tell what I do to enhance audio, I wanted to dedicate a song to this person. What do I receive? Something like, "you dumb f'k, it should be Joint Stereo, not Stereo"! Always believed Stereo setting offered more than Joint Stereo, though Joint Stereo offers a smaller file, not better sound. True/False?

MP3 encode decode can lead to overshoots up to 2 dB. Empirically
determined. Always leave 2.5 dB unused.

Kind regards

Ahh, the dreaded 'ISP's(inter-sample peaks).
Thought discussion of those was forebidden
in this group, LOL.


Well, using my EARS, a lot of the old MP3s
do sound more open and snappy than the
same track off the CD. That kinda jibes with
what the DR snapshots are telling me.

Remember all those times when you've boasted that you can't understand
numbers, and you can't even add 1 + 1? You've hammered away at that point
for years. You hate numbers, and you have no understanding what they mean.
You have no idea what the DR value means; you dont know how it's
calculated, and you dont know how to interpret it. In your desperate and
pathetic attempt to evaluate music by staring at your computer screen,
you've failed yet again. The root cause is that you're a retarded dumb ****.
Stay away from numbers, l'il buddy. The aren't telling you anything about
the music. They're just confusing and upsetting you, and we all know that
you can't handle much more confusion without reaching a breaking point.

Some of it, but likely a lot of it has to do with overshoot from the MP3
encode/decode process. That is likely to increase the peak measurement by
a couple decibels. Which is why, as I keep pointing out, relying entirely
on a peak vs. average ratio is so misleading.
