LTV assertion: Issue #1348 regression in +10dB decoder test
Basic info
LTV test job ivas-pytest-compare_ref-long-dec-lev+10 (#490206) · Jobs · SA4 / Audio / IVAS BASOP · GitLab reported an assertion for +10dB test case.
Test case: test_param_file_tests[ltv-stereo at 32 kbps, 48kHz in, 48kHz out, random FER at 18% with long bursts]
Error:
