Causes and symptoms of the malfunction
There is an error in the low-frequency loudness value correction for ISO 532B loudness (100-200 Hz band), which may result in incorrect ISO 532B loudness calculation results.
The non-stationary loudness, sharpness, roughness, fluctuation intensity, tonality (optional), and fluctuation sound analysis (optional) functions work without any problems.
