# Basic info <!--- Add commit SHA used to reproduce --> - Encoder (float): d18cbee34 - Decoder: 4e6c6d714 # Bug description With a somewhat specific combination, switching seem to be a bit worse in BASOP than they are in float reference. The combination is: - MASA 2TC - Output BINAURAL - Bitrate switching (attached profile) - DTX - FER - max_band == WB - Output FS 16 kHz Here is a diff figure to float ref. Best example is marked at 94 seconds.  # Ways to reproduce Using existing files (LTV and delay error profile) and attached rate switching pattern, replicate with following commands [generic_start_13k2_20frames.bin](/uploads/f937003dbaf6415362c7c22d0c777ded/generic_start_13k2_20frames.bin) ``` IVAS_cod_flt_ref -masa 2 ltv48_MASA2TC.met -max_band wb -dtx generic_start_13k2_20frames.bin 48 ltv48_MASA2TC.wav test.bs eid-xor -fer -vbr -bs g192 -ep g192 test.bs ep_10pct.g192 test.bs_eid IVAS_dec BINAURAL 16 test.bs_eid out.wav ``` <!--- Below are labels that will be added but are not shown in description.
