"Improve DTX testing coverage in SBA"
Reason why this change is needed
Improve the SBA DTX mode testing using genuine noisy SBA test vectors
Description of the change
New noisy SBA test vector is added to the scripts\testv folder
Affected operating points
All test cases in test_param_file.py involving SBA DTX use the newly generated test vector stv3OA48n.wav and its variants instead of stv3OA48c_cut_.004.wav.
