We sincerely apologize for bothering you during this busy time, but we would appreciate your understanding and cooperation.
If you have any questions or concerns, please contact our customer service department listed below.
Causes and symptoms of the malfunction
Time constant: In the case of Impulse, the rising time constant should be 35ms and the falling time constant should be 1500ms, but the processing was being performed with a falling time constant of 35ms.
When performing an analysis using the 1/N octave analysis function with the time constant set to Impulse, the decay of AllPass and A-characteristic AllPass in the trend graph appears faster than it actually is, and the AllPass and A-characteristic AllPass values in the calculation results panel are displayed as smaller.
*The display of each band level, both in graphs and values, is correct.
