MP3 Sound Quality Problems!

Ok, I did a little experiment today because I thought there was something fishy about the bass coming from some mp3s:
I listened to the same song on both my real CD and the burned MP3 CD I had of the same song that I downloaded from the net. Beign the same song, the bass produced on the purchased CD was much higher than on the burned CD. Is it because I downloaded the song or is it simply because the file is an MP3? I thought I read something about the compression of MP3 files resulted in a loss of certain frequencies. Is this true? If it is just the fact that it was downloaded and was a bad source, I will just rip the songs from my own CDs at a high bit rate. If all MP3s are like this, I will just get a regular CD player because I it is a waste to buy nice speakers when the source is bad quality. Thanks for any help you can provide.

Rip them from your own CD's and encode them at a higher quality. Right now I am encoding all of my mp3's at 256kbps, 44kHz, stereo, HQ. I use the LAME codec. That should do the trick. You never know how the mp3's were encoded that you download. Let me know if you have any other questions.

ya it's better to rip them yourself off of cd's otherwise you'll take a lot of time trying to get them at a good listenable frequency UncleB is right

I'm guessing that you were probably listening to a low bitrate MP3. Majority of my MP3s are 192kbps, and they sound pretty good.
160 is borderline, 128 is definitely yuck. So you might want to rip your own (fairly easy) or download 192+ mp3s.

To rip 'em, I recomment the LAME codec (for compressing mp3s) that uncleb mentioned and use EAC to rip the tracks.

Go here for more info and where to get these programs:

mp3s are compressed so you lose a lot of the music frequencies where as a cd plays more

I second using the lame codec at either 256 or vbr R3mix settings . (vbr works well with lame)
CDex is a really good ripper/encoder for mp3's. Check out R3mix.net for info on mp3 sound quality.

no reason to get MP3's at more than 192 kbps because that is what REAL CD's are at? You can't rip a CD any higher than what is at at. It's like trying to get 400HP out of our engines, can't do it. Anyway, you will lose some frequencies because that is how MP3's work. It eliminates sounds that you cannot hear or that speakers do not reproduce well. If you have a nice system, you might lose some of the REALLY low frequencies that you FEEL! I never notice that to be the case when I burn MP3 cd's though. Hope this helps.
