Basic info

Bug description

For decoding of the attached 96 kbps Stereo bitstream, I can observe a relatively large max. abs. diff, likely to come from the IGF.

Diff BASOP - Float:

For the neighboring stereo bitrates, this difference is much smaller:

	Max. abs. diff
Stereo_48kbps	294
Stereo_64kbps	189
Stereo_96kbps	1524
Stereo_160kbps	182
Stereo_256kbps	33
