how does LP 4 sound for mp3s.. i usually use lp2 but was wondering how LP4 sounds.. my mp3s are usually 190kb so sound quality isnt the most important thing.. all the stuff i love i have on cd so these are albums i jus want but dont neccesarily love.

I tried Lp4 one time on my deck and didnt like it too much, everything sounded quite compressed, and well, boring (a hell of a lot of artifacts flying around).

I think it compares to 66kb mp3's (or is 64kb...can't remember).

Those 190kb mp3's will sound...eh...very bad once compressed to Lp4, imho.

LP4 is usually used if you've got cheapo earbuds (the free ones that come with your portable device) and are on the move in noisy environments, but most people I know use LP4 for voice recordings.
I only use LP2 when I want to sqeeze a double CD album onto one disc. LP2 is suited more to rock/rap/techno IMO, but I have a disc with some Matchbox 20 and Vertical Horizon on it and it sound good to me.

SP=292kbps
LP2=~140kbps
LP4=~96kbps

Usually, I don't record any MP3s to MD if they have a bit rate less than 192kbps. Some 160kbps and 128kbps might find their way to a disc if they are really good.

I've found standard ATRAC to be as good or better than any 320k MP3. I equate LP2 to 192-256k MP3. LP4 is really only good for mono or speech, and is approximately equal to 96 MP3 or poor-quality 128k MP3.

Um, i got this info from www.minidisc.org:

"Standard ATRAC ("SP") is 292kbps, LP2 is ~132kbps, LP4 is ~66kbps. The LP mode bitrates are not simply 146kbps (292/2) and 73kbps (292/4) for this reason: In LP2 and LP4 modes 20 bytes of dummy data per 212 byte soundgroup are used to keep compatibility with SP mode, making them appear as normal ATRAC soundgroups containing silence. This allows LP2/4 tracks to play as silence on non-MDLP equipment. The intention is that older MD units should not produce random digital noise when playing LP tracks."

Gloco, those are what the different ATRAC levels actually are in terms of data rates. However, my post was regarding what the compare to in terms of MP3

Actually, i was directing that towards Mystyler, but your point is well taken

Cheers for pointing that out, gloco!
I can't explain why I typed 96k...

That's cool dude, the 6 is right below the 9 on the keypad anyway
