I appologize in advance if this message doesnt fit in here!
Here is my problem: (please read it)
I have a bet going on with someone. He claims he can hear difference between mp3 and CD. I dissagree. So here's what I plan to do: He will provide a CD with 5 or 6 tracks. It will be sort of "audiophile" CD. I have to encode it to mp3 and then make 4 or 5 CDs from that, with mixed CD and mp3 tracks. Some tracks will be from CD directly and some will be decoded from mp3 to audio.  I plan to use LAME encoder, because I heard it's the best one. I don't know what exact parametrs to use, so any help would be appreciated. I suppose if I use high bitrate it shouldn't be possible to hear difference between mp3 and direcd digital copy.
My opponent in this bet has sort of "good" equipment in his house and he claims he can hear above 20000 Hz, which I doubt. Please help me, I would surely like to show him he's wrong.
Thank you in advance,

I think you can add -Z for even higher quality, but that might be only on --ap standard and extreme.

We didn't specify bitrate at all, so I'm going to use highest bitrate possible. I suppose he really thinks I will do a 128kbit mp3s.

It is very likely that he can hear the difference. It is not likely that he can hear it on any audio sample if a high quality commandline was used with LAME; though it is possible that he can hear a difference no matter what commandline was used if he finds a good killer sample.

I doubt it too but it's not impossible.
He might be able to hear a 20000Hz signal but if he can pick if it's missing the music I can't believe.

Please help me win this bet. 

Or even the old 320 kbps  setting (cbr)

You better hope he doesn't bring you CD that is gapless, if he does no setting will help you.

    --nogap <file1> <file2> <...>
                    gapless encoding for a set of contiguous files
    --nogapout <dir>
                    output dir for gapless encoding (must precede --nogap)

Hmm... would it be cheating to use a "freeformat" stream?

Thanx to everyone.

Case: Can you be more specific? Why is that?

This is silly. He claims he can hear the difference between MP3 and CD and he's absolutely right. What's the point of using API other than to realize that you are on the wrong side of the bet and that you're trying to find someway around MP3's very real limitations?

What are you trying to say? It's not possible to get MP3's that are indistuinguishable from CD for the great majority of music you throw at it?

I think it is.

And I think it's rather silly to conjure some super LAME API-modified command line to somehow make up for MP3's limitations because who in the real world uses 320kbps 2 channel lossy files anyway?

Why not?  It's nearly 4.4:1 compression over the original .wav file, and if it's *really* transparent then that's certainly better than can be achieved by any lossless compression algorithm.

he couldn't even distinguish blade@128 from the original
