As this is EXT output, the difference is in the transports. Based on listening, there are at least two clear parts with difference. - At 4-5 s, the BASOP one seems to contain "something more" - At 7-9 s, the noise envelope is different - At 16-18 s, the BASOP one is missing something (this shows in plot as well) Here is time domain plot of full float vs. BASOP enc to float dec.  # Ways to reproduce Box folder: ...\Box_EXTERNAL_IVAS_BASOP_VERIFICATION\issues\issue-1775 <!-- Commandline or script --> Inputs are in Box ```bash IVAS_cod -masa 2 BASOP_Selection_MUSHRA-7ad_s04.met -max_band wb -dtx 32000 48 BASOP_Selection_MUSHRA-7ad_s04.wav test_1000.bs IVAS_dec EXT 48 test_1000.bs 1000_BASOP_Selection_MUSHRA-7ad_s04.wav_32k_48-48___EXT.wav ``` <!--- Below are labels that will be added but are not shown in description.
