Causes and symptoms of the malfunction
When performing an analysis with the time weight set to Impulse, there was a bug in the processing of the remaining levels when switching from a falling time constant of 1500ms to a rising time constant of 35ms.
When time weighting is set to Impulse during octave analysis, the values for each band and the Allpass may become larger than the correct values.
