When observing the difference signal, especially for the FER condition, differences in the higher bands are apparent:  MLD is around 1.7 for both clean and FER conditions, but the differences in the signal seem like a bug. # Ways to reproduce Clean condition ```bash ./IVAS_cod_flt_ref -mc 5_1 -max_band FB 80000 48 experiments/basop-verification/MC-5_1/proc_input/bm2aa1s12.wav out/mc-5_1--bm2aa1s12--80000.192 ./IVAS_dec_fx 5_1 48 out/mc-5_1--bm2aa1s12--80000.192 out/mc-5_1--bm2aa1s12--80000.clean.dec.5_1.fx.wav ./IVAS_dec_flt_ref 5_1 48 out/mc-5_1--bm2aa1s12--80000.192 out/mc-5_1--bm2aa1s12--80000.clean.dec.5_1.flt.wav ``` FER condition ```bash ./IVAS_cod_flt_ref -mc 5_1 -max_band FB 80000 48 experiments/basop-verification/MC-5_1/proc_input/bm2aa1s12.wav out/mc-5_1--bm2aa1s12--80000.192 eid-xor -vbr -fer out/mc-5_1--bm2aa1s12--80000.192 error_patterns/mc-5_1--bm2aa1s12--80000_ep.192 out/mc-5_1--bm2aa1s12--80000.fer.192 ./IVAS_dec_fx 5_1 48 out/mc-5_1--bm2aa1s12--80000.fer.192 out/mc-5_1--bm2aa1s12--80000.fer.dec.5_1.fx.wav ./IVAS_dec_flt_ref 5_1 48 out/mc-5_1--bm2aa1s12--80000.fer.192 out/mc-5_1--bm2aa1s12--80000.fer.dec.5_1.flt.wav ``` <!--- Below are labels that will be added but are not shown in description.
