Stereo decoding with JBM: energy difference in right channel despite similar TSM
# Basic info <!--- Add commit SHA used to reproduce --> - Encoder (float): d18cbee3417bc331630e6dcf214908deacdc8167 - Decoder: 8f97e97c0121cc13d69a9ac096f88d148f89e39c # Bug description In JBM decoding where same TSM between float and fixed-point decdoer seems to be applied, there is a signal section with high MLD. The right channel is attenuated wrt the float reference: Float ref: ![Screenshot_2024-10-28_at_16.20.52](/uploads/2d19c718702299b866d0568d3c0ef1cf/Screenshot_2024-10-28_at_16.20.52.png) Fixed-point: ![Screenshot_2024-10-28_at_16.20.47](/uploads/a25d211d7fb778a6bb10f81a212c8f7e/Screenshot_2024-10-28_at_16.20.47.png) Tracefile outputs for both decoders are identical, so same TSM is applied. # Ways to reproduce ``` ./IVAS_dec_fx -voip -Tracefile out/stereo-mixed-music--am1aa1s12--80000.jbm-dly_error_profile_8.dectrace.fx stereo 48 out/stereo-mixed-music--am1aa1s12--80000.netsimout-dly_error_profile_8.192 out/stereo-mixed-music--am1aa1s12--80000.jbm-dly_error_profile_8.dec.fx.wav ./IVAS_dec_flt_ref -voip -Tracefile out/stereo-mixed-music--am1aa1s12--80000.jbm-dly_error_profile_8.dectrace.flt stereo 48 out/stereo-mixed-music--am1aa1s12--80000.netsimout-dly_error_profile_8.192 out/stereo-mixed-music--am1aa1s12--80000.jbm-dly_error_profile_8.dec.flt.wav ``` Bitstream will be shared separately as usual. <!--- Below are labels that will be added but are not shown in description.
