The level is significantly higher than in float, and is also higher compared to decoding to 7_1 and using the (fixed-point) IVAS_rend renderer which renders it to binaural. **BASOP (decoding to binaural)** {width="1203" height="912"} **Float (decoding to binaural)** {width="1203" height="912"} **BASOP (decoding to 7_1 + subsequent rendering to binaural using IVAS_rend)** {width="1203" height="912"} # Ways to reproduce Box folder: ...\\Box_EXTERNAL_IVAS_BASOP_VERIFICATION\\issues\\issue-1801 **Decoding to binaural:** <!--Commandline or script--> ```bash IVAS_dec binaural 48 am3aa1s03_WB_128kbps.192 out_binaural.wav ``` **Decoding to 7_1 + rendering to binaural:** ```bash IVAS_dec 7_1 48 am3aa1s03_WB_128kbps.192 out_7_1.wav IVAS_rend -i out_7_1.wav -if 7_1 -of binaural -o out_7_1_binaural.wav ``` <!--- Below are labels that will be added but are not shown in description.
