To make sure I wasn't just imagining things, I tried it again. I doubt it
would be the file I was encoding, I tried "When I Grow Up" by Garbage. I
used the following command line lame -h -b 160, that's it. It makes no
difference whether I use -h or not, I tried it with and without. Here is the
exact command line output.
C:\audiograbber>lamei -b 160 3.wav 3.mp3
LAME version 3.68 (alpha 1) (www.sulaco.org/mp3)
GPSYCHO: GPL psycho-acoustic and noise shaping model version 0.77.
Using polyphase lowpass filter, transition band: 17960 Hz - 18494 Hz
Encoding 3.wav to 3.mp3
Encoding as 44.1 kHz 160 kbps j-stereo MPEG1 LayerIII ( 8.8x) qval=5
Frame | CPU/estimated | time/estimated | play/CPU | ETA
7829/ 7829(100%)| 0:03:01/ 0:03:01| 0:03:02/ 0:03:02| 1.1270| 0:00:00

Lamei was compiled with the Intel Compiler, lamem with MSVC 5. I swear I
haven't changed anything. I just copied and pasted. Don't ask me why it's
doing that, I am no programmer, but I was just letting you know that I
encountered a difference. If there is anything you want me to, hey I'll try
to help though.
