SBA PLC Decoder: Big diffs between Float and BASOP
# Basic info <!--- Add commit SHA used to reproduce--> - Float reference: - Encoder (float): 957cd45f4d6e88fb0f52d5b1df258c1668a9c61e - Decoder (float): 957cd45f4d6e88fb0f52d5b1df258c1668a9c61e - Fixed point: - Encoder (fixed): n/a - Decoder (fixed): ca3146eb9de8185ed0247945c643267826a32a94 # Bug description For decoding the attached bitstream, there are very big differences between IVAS float and BASOP decoder. I suspect this happens during PLC and I'm not sure whether it's audible, but it makes the comparison between float and BASOP really difficult. **Diff BASOP - Float:** ![Bildschirmfoto_2025-08-25_um_21.03.13](/uploads/f62a2931f887765954d5a2b5806548a8/Bildschirmfoto_2025-08-25_um_21.03.13.png) # Ways to reproduce <!--Commandline or script--> ```bash IVAS_dec FOA 48 ltv48_FOA_ivasbr96k_DTX0_Gain0_PLperc42mblen2.192.fer out.wav ``` Bitstreams: [ltv48_FOA_ivasbr96k_DTX0_Gain0_PLperc42mblen2.zip](/uploads/fd8a7f2f8e0739ddb84812237b926c8e/ltv48_FOA_ivasbr96k_DTX0_Gain0_PLperc42mblen2.zip) <!--- Below are labels that will be added but are not shown in description.
