Hi,
I am working with somebody who reported that there was a great boost in signal when the GEQBand module
was changed from bypassed to active. The settings are in the bass range.
I am attaching a picture of the module, the inspector and the variables (properties). Under the Arguments the order is 8.
In the attached picture it says it was set to -3.3 but when the bass boost event happened, it was set to 1.
The AW version that is running is AWE 5.16. B04.
Is this related to the a different query regarding a SOF filter when set too low, it will not compute properly?
The target is running at 192k and somebody mentioned about there is a lower limit to setting filter too low.
If you think it is related to the high sampling rate, can this be circumvented by decimation/interpolation?
OR
Can this issue occur more likely because of the state transition (BYPASSED to ACTIVE)?
Thanks.

Sorry I forgot to mention that when it changed to active, a very hot signal came across the system measuring around +20 dB.

Hi eenrique_dsp,
I suspect that you are experiencing quantization errors due to the high sampling rate and low cutoff frequencies. You may be able to use the precise graphic eq module (GraphicEQBandHP) to achieve these cutoff frequencies without audio artifacts.
If the high precision module doesn't work, see this discussion with another user who was experiencing the same issue: https://dspconcepts.com/forums/feature-requests-and-bug-reports/199-freq...
After properly decimating/interpolating the signal, he was able to achieve his desired frequency response even with a high Fs and very low cutoff frequencies.
Good luck, I hope this helps you
