look out in LAME's sources for a line like:
gfc->ATH_lower = (4-gfp->VBR_q)*4.0;
here you can see that the ATH is lowered

FS = Full Scale = maximum SPL possible for a sine wave.
Average Level is usually 10...14 dB below FS for modern music.
For any ATH calculation you must assign FS a SPL (Sound Pressure Level).
The ATH is different for different assignme
Hi Frank!
