I'am using Cdex with the Lame decoder and use an average bit rate of 175kbps (variable bit rate).

655850 2008-04-04 01:37:00 I have encoded a song to 128kbps and also 320kbps (originally from CD) and I can tell the difference instantly, If at home where it is quiet, on the train where it is loud etc makes no difference. The_End_Of_Reality (334)
655851 2008-04-04 02:53:00 I've been using MP3s for some time, now. Trust me, you'll be happier with a slightly higher bitrate than not.

I first encoded my entire music collection to 128 & on a reasonable car stereo -let alone my Denon & Polk Hi-Fi gear- the songs sounded c.r.a.p.

I then went to 160 & 224 bps. The only way to go is, as mentioned, with a variable bitrate. I use CDex. http://cdexos.sourceforge.net/

Here is a screenshot of my settings which give excellent compromise between quality & filesize (they aren't my own design. I simply copied them off a forum thread & found they give sound reproduction. If I can find out how to attack I will include, otherwise, I'll manually enter them.

Okay, here are the settings:

Bitrate min. =224
Bitrate max. =224
mode. =stereo
Quality. =High [Q=2]
VBR Method. =VBR-New
VBR Quality. =VBR 2
Output Sample Rate. =44100

655852 2008-04-04 03:25:00 Try WMA Lossless theortically they are. Only veterans of the sound world can tell quality we newbies don't know a thing. We only turn up the BASS which is useless as it compromises sound balance. JUST INSANE (6682)

655854 2008-04-04 10:44:00 I'm converting wav files to MP3 that have been created from vinyl LP's .
The wav conversion programme (Groove Mechanic) doesn't allow me to add title, album etc . I can't find a way to add this info when my Sony Media Manager software converts the files to MP3 and installs them on my Sony Walkman .

Is there a free converter out there that will encode this information as it converts the file from wav to MP3?

655855 2008-04-04 19:01:00 CDex allows something like this. You can add all album information from a databank by one klick. Crow1985 (6683)
655856 2008-04-04 23:48:00 I use the free audio grabber from freeware (http:) snapfiles, which you can add titles, etc. Also connects a database on the internet, which can sometimes auto add titles, etc for popular CD's. Maybe a mp3 tagger (www.mp3tag.de) might help, if you have hundreds of mp3's to rename, if they have their tags embedded...

If you want to know how mp3 works, then this good article - Behind The Mask, explains the theory of mp3's (www.soundonsound.com), and gives some tips to make the most out of mp3...
