# Basic info <!--- Add commit SHA used to reproduce--> - Float reference: - Encoder (float): - Decoder (float): - Fixed point: - Encoder (fixed): a0a3fc642 - Decoder (fixed): # Bug description The switch NONBE_FIX_ISSUE_2518 introduces a regression for the -10dB stereo LTV with DTX and bandwidth switching The figure below shows an example of problem at around 142s. In order : * Synthesis float * Synthesis fix with switch deactivate * Synthesis fix with switch activate {width="900" height="213"} # Ways to reproduce <!--Commandline or script--> ```bash test_param_file.py::test_param_file_tests[ltv_basop_encoder-stereo at 32 kbps, 48kHz in, 48kHz out, DTX on, bandwidth switching] or : IVAS_cod -max_band testv\bwidth_cntl.txt -dtx -stereo 32000 48 \m10dB_testv\ltv48_STEREO.wav encoded.fxd.test.bin ``` If you use the command line above with and with the switch activated, you can find issues at least at around 127s, 132s and 142s <!--- Below are labels that will be added but are not shown in description. This is a template to help fill them. Add further information to the first row and remove and add labels as necessary.-->
