 MP3 questions

I ripped all of my CD's to 128 bit per second MP3 files.
Is 192 or 256 bit per second a big difference? Does the music sound much better? If took me a whole fucking week to rip all of my cd's. I might be willing to do it again with a higher bit rate if the sound is a lot better. If it is only a little better then it is not worth it.

the 296 is usually better, but keep in mind that bitrates are only part of the equation; what encoder you used (and how it was used) plays a major role in the quality of the rip. what encoder did you use? what ripper?
I can definitely tell the difference between a 128 and a 256. The 128 has alot of data missing which makes highhats sound swishy and the lowend sound flat - this is unacceptable to my ears. Avoid "constant" bitrate and use a variable encoder. I highly recommend using a LAME encoder (3.96.1 is good) @ alt preset standard or extreme with a quality ripper like EAC or CDex. This is the best mp3 you can get. download
And if you have the harddrive space, I highly recommend forgetting about lossy compression and go with lossless. Lossless is an exact rip of a cd - they can be preserved and played on your computer. If you wish to put them onto an mp3 player, you can easily compress the file (saving the original file, of course) into a low-bitrate mp3 so to save space on your player. Once you have a lossless copy, you'll never have to rip again. I like .flac for lossless.

if those 128's sound fine to you then don't waste your time re-ripping all those CDs again... but if you REALLY want to know, then try taking one of your most dynamic CDs and one of your most "average" CDs and ripping them both at 128 and 192 and 256 and note the differences for yourself...
"And if you have the harddrive space, I highly recommend forgetting about lossy compression and go with lossless . . ." that is great advice...I personally ripped about 100 CDs to .ape and saved them all on to DVDs. I used to just listen to them in ape off my computer, but it inevitably takes up too much space when you keep adding CDs... now for just playing them off my computer I use high quality ogg compression which gives me about a 3:1 compression and still sounds great.

I used CDex. I ripped all of my CD songs to 128 bit MP3's. Do you think I should re-rip them in 256? ...Then I could alter the 256 bit MP3's to 128's or whatever if I needed room on my MP3 player. I have plenty of room on my laptop, so I can do whatever I want to on it.

How do I go about doing that?
I guess I want it so that I have very high quality copies of songs on my laptop, and I can easily convert those songs to 128 bit MP3's if I don't have much space on my MP3 player.

Keep in mind that this will compress the data only to ~50% of its original size, thus a cd will take up ~400 mb of space on your harddrive.

id think its a big differance. it kinda depends on how good your speakers are. but id advise staying away from codecs like mp3 and encodeing in open source codecs like ogg vorbis and FLAC. if you want best quality look into lossless codec, they give you an exact copy

what encoder did you use?

I didn't use one. I loaded up CDex and my CD songs popped up. I selected the songs with my mouse and clicked on the "make compressed audio files" icon. CDex then proceeded to make the MP3's.

well, you always will use encoder if you are compressing a .wav to .mp3 - the encoder you used was just the default one for CDex (not sure which that is)
. If you open CDex and go to options>settings>encoder you can see what your settings are. I recommend downloading LAME from the link in my first post (the LAME that CDex comes with is slightly out of date - you want 3.96.1). Put the file (lame_enc.dll usually or just lame.exe) into your CDex folder - perhaps even put it into its own folder so the default lame_enc.dll is not erased. Under the encoder tab, select "external encoder" and browse to the location of your new LAME encoder. Under parameter, type in:
--alt-preset standard %s %d
Dont worry about what bittrate is selected in CDex. The parameter string above will encode the mp3s at alt preset standard (a damn good mp3 rip) which is a variable bitrate from 0 to 192 or so.
This is the mp3 encoding that I recommend. LAME @ aps is excellent.
