For reference see below the spectrum for the left channel for 3 consecutive frames starting from timestamp 0.240 ms, red represents BASOP and green is float: 0.240 ms  0.260 ms  0.280 ms  The input signal is of higher loudness (approx -13 LFKS), so I also tested with normalizing the input to -26 LKFS and the issue is still present. # Ways to reproduce Box folder: ...\Box_EXTERNAL_IVAS_BASOP_VERIFICATION\issues\issue-1308 <!-- Commandline or script --> ```bash IVAS_cod -stereo -max_band fb 96000 48 emese_48_STEREO.pcm emese_stereo_b96_fb_cbr.192 IVAS_dec STEREO 48 emese_stereo_b96_fb_cbr.192 emese_stereo_b96_fb_cbr.dec.STEREO.wav ``` <!--- Below are labels that will be added but are not shown in description.
