Time to follow up to myself and put my money where my mouth is.

If you go to www.wayga.org/transocde, you will find three MP3 files.

One of them is a straight WAV->MP3(128kb)
One of them is WAV->MP3(256kb)->WAV->MP3(128kb)
One of them is WAV->OGG(192kb)->WAV->MP3(128kb)

I ripped the track myself a few minutes ago using cdex and aside from editing
for time and a few second fadein/fadeout, it is unaltered.  It's a standard
rip from a CD at 44khz.

MP3 encoding was using lame with the only options being -b <bitrate>.
OGG encoding was using oggenc, also with the only option being -b <bitrate).
OGG/MP3 to WAV used ogg123/mpg123 respectively.  Only options were to have
each spit out WAV files instead of using the sound card.

In case you think I'm picking a stupid track, this is one of my standard
tracks for hearing music, as it has both bass and higher end sounds.
It's pretty complicated.  Track 2 of Enigma's second CD.

You may think I'm cheating by going from a higher bitrate to a lower one,
but this only proves the point if successful.

So...which is which?  I'd build a PHP site to collect votes, but I'm tired
as my daughter kept me up all last night.  Drop me a note and I'll send the
answers out sometime later.
