[ltv-regression] Significant MLD increase for ltv_basop_encoder-MASA 2TC at 128 kbps, 48kHz in, 48kHz out, FOA out
# Basic info <!--- Add commit SHA used to reproduce --> ## Old version - Float: - Encoder (float): 24152d66f - Decoder (float): 24152d66f - Fixed point: - Encoder (fixed): 26ae1a669 ## New version - Float: - Encoder (float): aa956cc5e - Decoder (float): aa956cc5e - Fixed point: - Encoder (fixed): 060726532 # Bug description Daily LTV run shows MLD increase from 6.3 to 31.2 for one MASA test case, namely `ltv_basop_encoder-MASA 2TC at 128 kbps, 48kHz in, 48kHz out, FOA out`. Further inspection confirms that this comes from the switch `FIX_BASOP_2529_MASA_RATIO_SCALINGS` in MR !2942. As the fix itself is necessary, it is possible that the change in parameter values has caused issues further in the flow. This needs to be inspected. # Ways to reproduce <!-- Commandline or script --> Use this with various encoder and decoder versions. ```bash ./IVAS_cod -masa 2 ltv48_MASA2TC.met 128000 48 ltv48_MASA2TC.wav debug.bit ./IVAS_dec FOA 48 debug.bit out.wav ``` <!--- 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. -->
