MP3 bit rates, downsample software

A friend claims he's done numerous tests, and using the same encoder (and a decent one), can't tell the difference between 128kbps and anything higher. Must you have a high end system to notice by ear? Also he said CD's are 1140 kbps. Where did he get that? I've never heard that.

Also what's a good software that will downsample mp3's quickly and easily. Even better, something that will do it as your copying them to your hardware mp3 player?

He's deaf, has awful speakers, or started with a low quality file.

No. I can tell with some normal cheap computer speakers, or headphones.

74 minutes, 650mb -> 8.78mb/min -> ~1400kilobytes per second (quick verification: .15mb/sec * 60sec/min * 74min/CD -> ~650 mb). Winamp also shows 1440 (I think) on CDs.

edit: I don't disagree with anything EeyoreX said in his reply to this post.

Or he simply can't hear a difference. Not everyone can.

Just because you can tell the difference doesn't mean everyone else can. Your post makes the OPs friend sound "wrong" when he is, in fact, not wrong at all. "Audiophiles" "hear better" than the majority of people, yay for them. Personally I don't hear all that much difference myself. I am not "wrong" I am just not all that impressed with the difference between 128kb/s and bitrates that are higher.

The bottom line: listen with your ears and ignore the number. If 128kb/s sounds good to you, what difference does it make if 320kb/s is "better"?

dbPowerAMP Music Converter is easy. I don't think it can do your "on the fly" copying while moving to a player.

Can dbPowerAMP Music Converter can convert MP3 to WMA? Or Easy audio file converter or Goldwave?

Anyone else know any that convert and/or downsample on the fly?
 
I am 99% sure that WMA is supported via codec install. I am not sure about the others. Check here for a list of codecs dBPowerAMP can use.
